Frank Anthony Wilczek (; born May 15, 1951) is an American theoretical physicist, mathematician and a Nobel laureate. He is currently the Herman Feshbach Professor of Physics at the Massachusetts Institute of Technology (MIT), Founding Director of T. D. Lee Institute and Chief Scientist at the Wilczek Quantum Center, Shanghai Jiao Tong University (SJTU), Distinguished Professor at Arizona State University (ASU) and full Professor at Stockholm University.
Born in Mineola, New York, Wilczek is of Polish and Italian origin. His grandparents were immigrants, who "really did work with their hands," according to Wilczek, but Frank's father took night school classes to educate himself, working as a repairman to support his family. Wilczek's father became a "self-taught engineer," whose interests in technology and science inspired his son.
Wilczek was educated in the public schools of Queens, attending Martin Van Buren High School. It was around this time Wilczek's parents realized that he was exceptional--in part as a result of Frank Wilczek having been administered an IQ test.
After skipping two grades, Wilczek started high school in the 10th grade, when he was 13 years old. He was particularly inspired by two of his high school physics teachers, one of whom taught a course that helped students with the national Westinghouse Science Talent Search. Wilczek was a finalist in 1967 and ultimately won fourth place, based on a mathematical project involving group theory.
He received his Bachelor of Science in Mathematics and membership in Phi Beta Kappa at the University of Chicago in 1970. During his last year at Chicago, he attended a group theory course taught by Peter Freund, which discussed many of the then-exciting ideas about particle physics.
Wilczek met Betsy Devine at Princeton, when both watched the televised 1972 Fisher-Spassky chess matches. They married on July 3, 1973, and together they have two daughters, Amity (Academic Dean at Deep Springs College) and Mira (senior partner at Link Ventures.)
Wilczek is a member of the Scientific Advisory Board for the Future of Life Institute, an organization that works to mitigate existential risks facing humanity, particularly existential risk from advanced artificial intelligence.
In 2014, Wilczek penned a letter, along with Stephen Hawking and two other scholars, warning that "Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks."
Wilczek is also a supporter of the Campaign for the Establishment of a United Nations Parliamentary Assembly, an organization which advocates for democratic reform in the United Nations, and the creation of a more accountable international political system.
Wilczek became a foreign member of the Royal Netherlands Academy of Arts and Sciences in 2000. He was awarded the Lorentz Medal in 2002. Wilczek won the Lilienfeld Prize of the American Physical Society in 2003. In the same year he was awarded the Faculty of Mathematics and Physics Commemorative Medal from Charles University in Prague. He was the co-recipient of the 2003 High Energy and Particle Physics Prize of the European Physical Society. The Nobel Prize in Physics 2004 was awarded jointly to David J. Gross, H. David Politzer and Frank Wilczek "for the discovery of asymptotic freedom in the theory of the strong interaction." Wilczek was also the co-recipient of the 2005 King Faisal International Prize for Science. In that same year, he received the Golden Plate Award of the American Academy of Achievement. On January 25, 2013, Wilczek received an honorary doctorate from the Faculty of Science and Technology at Uppsala University, Sweden.
Wilczek holds the Herman Feshbach Professorship of Physics at MIT Center for Theoretical Physics. He has also worked at the Institute for Advanced Study in Princeton and the Institute for Theoretical Physics at the University of California, Santa Barbara and was also a visiting professor at NORDITA.
Wilczek's 2004 Nobel Prize was for asymptotic freedom, but he has helped reveal and develop axions, anyons, asymptotic freedom, the color superconducting phases of quark matter, and other aspects of quantum field theory. He has worked on condensed matter physics, astrophysics, and particle physics.
In 1973, while a graduate student working with David Gross at Princeton University, Wilczek (together with Gross) discovered asymptotic freedom, which holds that the closer quarks are to each other, the less the strong interaction (or color charge) between them; when quarks are in extreme proximity, the nuclear force between them is so weak that they behave almost as free particles. The theory, which was independently discovered by H. David Politzer, was important for the development of quantum chromodynamics. According to the Royal Netherlands Academy of Arts and Sciences when awarding Wilczek its Lorentz Medal in 2002,
This [asymptotic freedom] is a phenomenon whereby the building blocks which make up the nucleus of an atom - 'quarks' - behave as free particles when they are close together, but become more strongly attracted to each other as the distance between them increases. This theory forms the key to the interpretation of almost all experimental studies involving modern particle accelerators.
In 1977, Roberto Peccei and Helen Quinn postulated a solution to the strong CP problem, the Peccei-Quinn mechanism. This is accomplished by adding a new global symmetry (called a Peccei-Quinn symmetry.) When that symmetry is spontaneously broken, a new particle results, as shown independently by Wilczek and by Steven Weinberg. Wilczek named this new hypothetical particle the "axion" after a brand of laundry detergent, while Weinberg called it "Higglet." Weinberg later agreed to adopt Wilczek's name for the particle.
Although most experimental searches for dark matter candidates have targeted WIMPs, there have also been many attempts to detect axions. In June, 2020, a team of Italian physicists detected a signal that appeared to be axions.
In physics, an anyon is a type of quasiparticle that occurs only in two-dimensional systems, with properties much less restricted than fermions and bosons. In particular, anyons can have properties intermediate between fermions and bosons, including fractional electric charge. This anything-goes behavior inspired Wilczek in 1982 to name them "anyons."
In 1977, a group of theoretical physicists working at the University of Oslo, led by Jon Leinaas and Jan Myrheim, calculated that the traditional division between fermions and bosons would not apply to theoretical particles existing in two dimensions. When Daniel Tsui and Horst Störmer discovered the fractional quantum Hall effect in 1982, Bertrand Halperin (1984) expanded the math Wilczek proposed in 1982 for fractional statistics in two dimensions to help explain it.
In 2012 he proposed the idea of a time crystal. In 2018, several research teams reported the existence of time crystals. In 2018 he and Qing-Dong Jiang calculated that the so-called "quantum atmosphere" of materials should theoretically be capable of being probed using existing technology such as diamond probes with nitrogen-vacancy centers.
Somewhere between working class and lower middle class. Yeah, lower middle class, I guess I would say. Unlike my grandparents, who really did work with their hands, my father, as I said, was kind of a technician and repairman. He actually got very good at the job and was rising through the ranks.
Frank Wilczek's story starts in Queens, New York, where he grew up in a working-class family with roots in Europe. They were children of the Great Depression from Long Island and had limited access to resources, but that didn't stop them from working to educate themselves. Frank's father was a self-taught engineer and passed his interest in technology and science on to his son.
As a high school senior, Wilczek was a finalist in the national Science Talent Search. He says his premise about mathematical structures called groups was the best part of his project, posing 'a sensible question for someone to ask at that stage.'
'I noticed that whatever moves Frank called out, the players would do what he said. They'd make the moves he predicted. This happened even when what he called out was different from what others called out,' recalled Devine.
A team of physicists has made what might be the first-ever detection of an axion. Axions are unconfirmed, hypothetical ultralight particles from beyond the Standard Model of particle physics, which describes the behavior of subatomic particles. Theoretical physicists first proposed the existence of axions in the 1970s in order to resolve problems in the math governing the strong force, which binds particles called quarks together. But axions have since become a popular explanation for dark matter, the mysterious substance that makes up 85% of the mass of the universe, yet emits no light.
Then, in 1977 Helen Quinn and the late Roberto Peccei, both then at Stanford University, proposed a solution: perhaps there is a hitherto unknown field that pervades all of space and suppresses the neutron's asymmetries. Later, theoretical physicists Frank Wilczek and Steven Weinberg deduced that if the Standard Model were tweaked to allow such a field, it would imply the existence of a new particle, dubbed the axion. (Wilczek got the idea for the name from a brand of laundry detergent.)
In 1982 physicist Frank Wilczek gave these interstitial particles the name anyon...'Any anyon can be anything between a boson or a fermion,' Keilmann says. 'Wilczek is a funny guy.'
In the early 1980s I named the hypothetical new particles 'anyons,' the idea being that anything goes - but I did not lose much sleep anticipating their discovery. Very soon afterwards, however, Bert Halperin at Harvard University found the concept of anyons useful in understanding certain aspects of the fractional quantum Hall effect, which describes the modifications that take place in electronics at low temperatures in strong magnetic fields.CS1 maint: date and year (link)
The appearance of fractional statistics in the present context is strongly reminiscent of the fractional statistics introduced by Wilczek to describe charged particles tied to "magnetic flux tubes" in two dimensions.
In the early 1980s, physicists first used these conditions to observe the 'fractional quantum Hall effect,' in which electrons come together to create so-called quasiparticles that have a fraction of the charge of a single electron. (If it seems strange to call the collective behavior of electrons a particle, think of the proton, which is itself made up of three quarks.) In 1984, a seminal two-page paper by Wilczek, Daniel Arovas and John Robert Schrieffer showed that these quasiparticles had to be anyons.
The existence of anyons - which get their name from the fact that their behaviour is neither fermion-like or boson-like - was predicted in the early 1980s by the theoretical physicist Frank Wilczek. Soon afterwards, another physicist, Bert Halperin, found that anyons could explain certain aspects of the fractional quantum Hall effect, which describes the changes that take place in electronics at low temperatures in strong magnetic fields. Then, in 1984, Dan Arovas, Bob Schrieffer and Wilczek proved that a successful theory of the fractional quantum Hall effect does indeed require particles that are neither bosons or fermions.
