Tuesday, March 1, 2016 - 2:00pm
Physics 278
Speaker: Brian Tennyson, Yale University
Two-phase liquid noble element-based detectors are used in a variety of fundamental physics experiment applications. This seminar will focus on xenon-based detectors, specifically the Large Underground Xenon (LUX) experiment and the Particle Identification in Xenon at Yale (PIXeY) and Compton-... Read More »

Physics 298
Speaker: Adriana Moreo (University of Tennessee, ORNL)
The phase diagram of electron-doped pnictides as a function of temperature, electronic density, and isotropic quenched disorder strength obtained by means of computational techniques applied to a three-orbital (xz, yz, xy) spin-fermion model with lattice degrees of freedom will be presented. In... Read More »

Raleigh, NC 
Speaker: Shunsaku Horiuchi (Virginia Tech.)
Massive stars end their lives in a violent core collapse. While the expectation for the majority of them has been the formation of a protoneutron star and an optical supernova explosion, an alternate channel is the collapse to a black hole with only a limited optical transient. I will discuss... Read More »
Wednesday, February 17, 2016 - 3:30pm
Physics 130
Speaker: Jonathon Howard (Yale)
"Swimming Strokes of Microorganisms: Collective Motion by Molecular Motors" The beating patterns of sperm flagella and the breast-stroke like swimming strokes of ciliates are driven by the molecular motor dynein. This motor generates sliding forces between adjacent microtubule doublets within the... Read More »
Tuesday, February 16, 2016 - 3:30pm
Raleigh, NC 
Speaker: Mukund Rangamani (UC Davis)
I will describe how to arrive at an effective action for dissipative hydrodynamics starting from the microscopic Schwinger-Keldysh construction. The essential ingredients will the doubling of degrees of freedom, an emergent abelian symmetry that is associated with entropy, and a BRST supersymmetry... Read More »

Physics 298
Speaker: Arnab Banerjee (Oak Ridge National Laboratory)
In 2006, Alexei Kitaev proposed that certain 2D honeycomb magnets with a strong spin-orbit coupling in the low-spin (S=1/2) ground state and a high degree of bond anisotropy will form a quantum-spin-liquid (QSL). This QSL is special since its excitations can be solved exactly to predict the... Read More »
Tuesday, February 9, 2016 - 3:30pm
Physics 298
Speaker: Paul Romatschke (Univ. of Colorado)
In high energy collisions of heavy-ions, experimental findings of collective flow are customarily associated with the presence of a thermalized medium expanding according to the laws of hydrodynamics, which has been dubbed a 'quark-gluon plasma'. Just a few years ago, there was near consensus in... Read More »

Raleigh, NC 
Speaker: Mauricio Martinez (Ohio State)
TBA
Wednesday, January 27, 2016 - 3:30pm
Physics 130
Speaker: Laura Mersini-Houghton (UNC)
"Initial Conditions of the Universe" - I will describe my proposal for the wavefunction of the universe on the landscape multiverse which led to a theory of the selection of the initial conditions of the universe and a series of testable predictions. The series of anomalies derived from this... Read More »
Tuesday, January 26, 2016 - 3:30pm
Physics 298
Speaker: Francesco Scardina (Catania)
One of the primary aims of the ongoing nuclear collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies is to create a Quark Gluon Plasma (QGP). The heavy quarks (HQ), charm and bottom constitutes a unique probe of the QGP properties. Both at RHIC and LHC... Read More »
