Speaker: Dragana Popovic (Florida State University)Host: Ar. AbanovUnderstanding the dynamics of isolated disordered systems and its dependence on the range of interactions has been attracting a lot of research attention in recent years, but many questions remain open, especially in two spatial dimensions. At the same time, experiments have been limited mostly to those on synthetic quantum [...]
Speaker: Henning Samtleben (Ecole Normale Supérieure de Lyon)I review new tools for the computation of Kaluza-Klein mass spectra associated with compactifications around various background geometries. Applications include the identification of non-supersymmetric AdS4 vacua which are perturbatively stable at all Kaluza-Klein levels.
Speaker: Noah A. Rubin (Harvard University)Metasurfaces are an emergent class of subwavelength diffractive optics. The individual elements comprising a metasurface may be designed with polarization sensitivity [1, 2] – in this way, metasurfaces can enable optical elements whose far-fields exhibit custom polarization-dependence. Using relatively simple design heuristics based on the Jones calculus, a variety of [...]
Speaker: Guido Pagano (Rice University)Host: Ar. AbanovLaser cooled trapped ions offer unprecedented control over both internal and external degrees of freedom at the single-particle level. They are considered among the foremost candidates for realizing quantum simulation and computation platforms that can outperform classical computers in specific tasks. In this talk I will show how linear arrays [...]
Speaker: Itamar Kimchi (Georgia Tech)Host: Ar. AbanovStudying quantum entanglement over the past decade has allowed us to make remarkable theoretical progress in understanding correlated many-body quantum systems. However in real materials electrons experience spatially random heterogeneities ("dirt") whose theoretical treatment, including strong correlations, has been a challenge. I will describe how synthesizing ideas from quantum information theory, statistical mechanics, and quantum field theory gives [...]
