Description:

I am a theoretical physicist working on a wide range of topics:particle physics beyond the standard model, quantum field theory,collider physics, dark matter, dark energy, inflation, grandunification, neutrino physics. More recently I work on condensed matterphysics and lead a collaboration on astronomycalled SuMIRe(video). I worked on KamLANDneutrino experiment underground (seethe evidence).For further information, seethe listof publications. My CV is here in PDF.My students have done very well. Nima Arkani-Hamed (Faculty, IAS) wasthe first student I worked with, even though he was officially astudent of Lawrence Hall. I officialy supervised Andr deGouv a (Faculty, Northwestern), Alexander Friedland (SeniorStaff, SLAC National Laboratory), Aaron Pierce (Faculty,Michigan), Daniel Larson (Lecturer, Harvard), Roni Harnik (SeniorStaff, Fermilab), Matt Buckley (Faculty, Rutgers), SouravMandal (Institute for Defense Analyses), Vikram Rentala (faculty,ITT Bombay), Willie Klemm (postdoc, Uppsala), Brian Henning (postdoc, Yale), Xiaochuan Lu (postdoc, UC Davis).Quantum UniverseHintze Lecture at Oxford 2015Where do we come from? Science is making progress on this age-old question of humankind. The Universe was once much smaller than the size of an atom. Small things mattered in the small Universe, where quantum physics dominated the scene. To understand the way the Universe is today, we have to solve remaining major puzzles. The Higgs boson that was discovered recently is holding our body together from evaporating in a nanosecond. But we still do not know what exactly it is. The mysterious dark matter is holding the galaxy together, and we would not have been born without it. But nobody has seen it directly. And what is the very beginning of the Universe?Dark MattersTalk at TEDxTokyo 2010Promotion video for Coursera MOOCNearly 50,000 students signed up for this online course from more than 140 countriesE=mc2A talk at Lawrence Berkeley National Laboratory on Einstein's famous equationMysteries of the Quantum UniverseA public talk at an IMAX theater at Science World in VancouverWhen a Symmetry Breaks (video)What is common among a magnet, a flounder, a rack of laundry, your heart on the left of your body, and the Higgs boson? The concept of spontaneous symmetry breaking is ubiquitous among many natural phenomena. I’ll describe the basic concept and its applications. In particular, the original concepts from Anderson, Nambu, Goldstone, and Higgs do not quite work in many systems that include a magnet on your fridge. I generalize the concept so that it is applicable to all known natural phenomena around us.Colloquium at Cornell on Oct. 19, 2015What's wrong with Goldstone? (PDF)Spontaneous Symmetry Breaking is a very universal concept applicablefor a wide range of subjects: crystal, superfluid, neutron stars,Higgs boson, magnets, and many others. Yet there is a variety in thespectrum of gapless excitations even when the symmetry breakingpatterns are the same. We unified all known examples in a single-lineLagrangian of the low-energy effective theory. In addition, we nowhave a better understanding of what happens with spacetime symmetries,and predict gaps for certain states exactly based on symmetries alone.Seminar at CERN on Dec 11, 2013
