Speaker: Gleb M. Akselrod
Gleb M. Akselrod (Duke University): Control of the radiative properties of emitters such as molecules, quantum dots, and color centers is central to nanophotonic and quantum optical devices, including lasers and single photon sources. Plasmonic cavities and nanoantennas can strongly modify the... Read More »

Chapel Hill N.C.
Speaker: Joaquin Drut (UNC Chapel Hill)
Location: UNC Chapel Hill, Phillips 277 The calculation of the entanglement properties of strongly coupled many-body systems, in particular Renyi and von Neumann entropies, continues to be an active research area with many open questions. In this talk, I will outline the challenges and describe... Read More »

Physics 298
Speaker: Jonathan Bares
The problems of solid fractures and granular media have occupied physicists and engineers for centuries. These phenomenons are classically addressed within the framework of continuum and discrete mechanics. Still, in both cases, stress concentration at the local scale along with intrinsic... Read More »

Physics Faculty Lounge
Speaker: K. T. Chao (Beijing)
Among the discovered new hadron XYZ states, the X(3872) might be the most elusive one. In this talk, I will briefly review the possible explanations of X(3872), and put stress on its production at hadron colliders. Based on the calculation in nonrelativistic QCD, we argue that a substantial $\chi_... Read More »

Physics 298
Speaker: Chung-Hou Chung (NCTU,Taiwan)
The resonant-level model is a paradigmatic quantum system which serves as a basis for many other quantum impurity models. We provide a comprehensive analysis of the non-equilibrium transport near a quantum phase transition in a spinless dissipative resonant-level model [1-4]. A detailed derivation... Read More »

Physics 298
Speaker: Jacques Soffer (Temple U.)
We will first recall why the nucleon spin sructure is such a difficult and subtle problem, not yet fully understood in QCD. We will then describe the quantum statistical approach to parton distributions and some recent results, in particular related to the nucleon spin structure. Future... Read More »

Raleigh N.C.
Speaker: Alain Coc (Paris)
Primordial nucleosynthesis (or BBN) is one of the three observational evidences for the Big¿Bang model. It is very special as it involves only a dozen main nuclear reactions and because, contrary to stellar models, within the standard BBN model, the thermodynamic con- ditions can be calculated from...

Physics 298
Speaker: Francois Amet (Stanford University)
The electronic properties of graphene are well described by a non-interacting Dirac Hamiltonian with a fourfold symmetry associated with spin and valley, an additional degree of freedom due to the hexagonal crystal lattice of graphene. As a result, graphene exhibits a variety of peculiar phenomena... Read More »
