Joseph David Lykken ({{IPAc-en|ˈ|l|ɪ|k|ən}} {{respell|LIK|ən}}) is an American theoretical physicist at the Fermi National Accelerator Laboratory and, from July 1, 2014 to Sept 6, 2022, he was the Deputy Director of Fermilab.{{cite web|url=http://www.fnal.gov/pub/today/archive/archive_2014/today14-07-02.html|title=Fermilab Today}} He is currently Director of Fermilab's Quantum Division.{{cite web|url=http://www.fnal.gov/pub/about/joseph-lykken.html|title=Fermilab | About Fermilab}}

Background and education

Lykken was born in Minneapolis, Minnesota.

He is the son of David T. Lykken, noted psychologist, behavioral geneticist, and twin researcher.

Lykken received his Ph.D. in 1982 from M.I.T. He arrived at Fermilab in 1989, where he worked in the Fermilab Theory Division,{{cite web|title=Fermilab Theory Division|url=https://theory.fnal.gov/|accessdate=13 August 2024}} and as a collaborator of the Compact Muon Solenoid (CMS) experiment at the CERN Large Hadron Collider.Joseph D.

Research

In 1983 Lykken's paper with Lawrence Hall and Steven Weinberg helped establish the minimal supersymmetric standard model as a leading paradigm for physics beyond the Standard Model.{{cite journal|title=Supergravity as the messenger of supersymmetry breaking|date=1983 |doi=10.1103/PhysRevD.27.2359 |url=https://journals.aps.org/prd/abstract/10.1103/PhysRevD.27.2359|accessdate=13 August 2024 |last1=Hall |first1=Lawrence |last2=Lykken |first2=Joe |last3=Weinberg |first3=Steven |journal=Physical Review D |volume=27 |issue=10 |pages=2359–2378 |bibcode=1983PhRvD..27.2359H |url-access=subscription }}

In 1996 Lykken proposed "weak scale superstrings," {{cite journal|title=Weak Scale Superstrings|date=1996 |doi=10.1103/PhysRevD.54.R3693 |url=https://journals.aps.org/prd/abstract/10.1103/PhysRevD.54.R3693|accessdate=13 August 2024 |last1=Lykken |first1=Joseph D. |journal=Physical Review D |volume=54 |issue=6 |pages=R3693–R3697 |pmid=10021103 |arxiv=hep-th/9603133 |bibcode=1996PhRvD..54.3693L }} which posited extra dimensions of space within the reach of particle colliders, such as the Fermilab Tevatron, and the CERN Large Hadron Collider. As a member of the

CMS collaboration, he was co-author of the Higgs boson

discovery paper,{{cite journal|url=https://www.sciencedirect.com/science/article/pii/S0370269312008581|title=Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC|date=2012 |doi=10.1016/j.physletb.2012.08.021 |bibcode=2012PhLB..716...30C |accessdate=13 August 2024 |last1=Chatrchyan |first1=S. |last2=Khachatryan |first2=V. |last3=Sirunyan |first3=A.M. |last4=Tumasyan |first4=A. |last5=Adam |first5=W. |last6=Aguilo |first6=E. |last7=Bergauer |first7=T. |last8=Dragicevic |first8=M. |last9=Erö |first9=J. |last10=Fabjan |first10=C. |last11=Friedl |first11=M. |last12=Frühwirth |first12=R. |last13=Ghete |first13=V.M. |last14=Hammer |first14=J. |last15=Hoch |first15=M. |last16=Hörmann |first16=N. |last17=Hrubec |first17=J. |last18=Jeitler |first18=M. |last19=Kiesenhofer |first19=W. |last20=Knünz |first20=V. |last21=Krammer |first21=M. |last22=Krätschmer |first22=I. |last23=Liko |first23=D. |last24=Majerotto |first24=W. |last25=Mikulec |first25=I. |last26=Pernicka |first26=M. |last27=Rahbaran |first27=B. |last28=Rohringer |first28=C. |last29=Rohringer |first29=H. |last30=Schöfbeck |first30=R. |journal=Physics Letters B |volume=716 |issue=1 |pages=30–61 |display-authors=1 |arxiv=1207.7235 }} and with Maurizio Pierini, Chris Rogan, and Maria Spiropulu, developed a new set of kinematic variables ("razor") targeting the discovery and characterization of new physics at the LHC.

Since 2018 he has been a member of the Quantum Communications Channels for Fundamental Physics (QCCFP) project, supported by the

QuantISED program of the U.S. Dept. of Energy Office of High Energy Physics.{{cite web|title=HEP Quantum Information Science|url=https://science.osti.gov/hep/Research/Quantum-Information-Science-QIS|accessdate=13 August 2024}} Accomplishments of this project include the first laboratory demonstration of traversable

wormhole teleportation, using a Google Sycamore quantum processor.{{cite journal|url=https://www.nature.com/articles/s41586-022-05424-3|title=Nature article: Traversable wormhole dynamics on a quantum processor|journal=Nature |date=December 2022 |volume=612 |issue=7938 |pages=51–55 |doi=10.1038/s41586-022-05424-3 |accessdate=13 August 2024 |last1=Jafferis |first1=Daniel |last2=Zlokapa |first2=Alexander |last3=Lykken |first3=Joseph D. |last4=Kolchmeyer |first4=David K. |last5=Davis |first5=Samantha I. |last6=Lauk |first6=Nikolai |last7=Neven |first7=Hartmut |last8=Spiropulu |first8=Maria |pmid=36450904 }}
