Physics 128
Speaker: Leong-Chuan Kwek
To circumvent the limitations of conventional computers in tackling complex physical processes, Richard Feynman proposed nearly thirty years ago a means of using well-understood quantum systems called quantum simulators (or quantum emulators) to emulate similar, but otherwise poorly understood,...

Physics 128
Speaker: Robin Canup (SouthWest Research Institute)
*CANCELLED** "Giant Impact Models of Lunar Origin" - Nearly all recent work on lunar origin has focused on the giant impact theory, which proposes that the collision of a planet-sized body with the forming Earth produced a disk of debris that later accumulated into the Moon. The impact theory is... Read More »

Physics 298
Speaker: Xiangdong Ji (U. of Maryland)
I introduce light-cone physics as a large momentum effective field theory (LMEF). This notion allows formulating Euclidean lattice calculations of parton physics which is otherwise considered impossible.
Monday, February 17, 2014 - 3:30pm
Physics 128
Speaker: Nick Ouellette (Yale)
** Please note this event is for Monday not Wednesday. ** "Collective Dynamics of Laboratory Insect Swarms" Self-organized collective animal behavior--in swarms, flocks, schools, herds, or crowds--is ubiquitous throughout the animal kingdom. In part because it is so generic, it has engaged and... Read More »

Physics 128
Speaker: Cenke Xu (USCB)
This event has been postponed due to the winter weather. It will be rescheduled later this semester. Spin liquid states are ground states of quantum spin systems that do not spontaneously break any global symmetry. In the last decade tremendous progresses have been made in searching for spin liquid... Read More »

Physics 298
Speaker: Krzysztof Redlich (Wroclaw U.)
We discuss results on the Polyakov loop susceptibilities in SU(3) lattice gauge theory. The longitudinal and transverse fluctuations of the Polyakov loop, as well as, that of its absolute value will be introduced in the context of the confinement-deconfinement phase transition. We will indicate... Read More »

Physics 278
Speaker: Pi-Jung Chang (Kansas State University)
In March 2012, the Double Chooz reactor neutrino experiment published its most precise result so far: sin22¿13 = 0.109 ± 0.030(stat.) ± 0.025(syst.). The statistical significance is 99.9% away from the no-oscillation hypothesis. The systematic uncertainties from background and detection efficiency... Read More »
Wednesday, February 5, 2014 - 3:30pm
Physics 128
Speaker: Mats A. Selen (University of IL)
"Tradition to Enlightenment The Evolution of Intro Physics at the University of Illinois" About 17 years ago we significantly changed the way we teach intro physics at UIUC. The innovation, which in hindsight seems almost trivial, was to define these courses in terms of their content and... Read More »
Monday, February 3, 2014 - 4:00pm
Physics 298
Speaker: Irakli Chakaberia (Kansas State University)
Particle physics, as it is known today, is a union of electroweak theory and quantum chronodynamics, collectively called the standard model (SM). Despite the tremendous success of the SM, it falls short of answering some of the fundamental questions of the nature, hence, cannot be considered the... Read More »
Tuesday, January 21, 2014 - 3:30pm
Physics 298
Speaker: Adrian Dumitru (Baruch CUNY)
I discuss the structure of longitudinal chromomagnetic fields which develop in heavy-ion collisions. Rather than being homogeneous, Bz is found to exhibit domain-like structures in the transverse plane. The expectation values of spatial Wilson loops exhibit area law scaling for radii larger than...
