Center-vortex condensation and monopole condensation in 4d gapped phases

Yui Hayashi (Tokyo U.)
Room 907 (16:00-18:00)

Abstract: Two famous scenarios for quark confinement are center-vortex proliferation and monopole condensation. We consider gauge-invariant criteria for center-vortex condensation and monopole condensation in terms of Z_N 1-form symmetry. The condensation of some soliton can be characterized by non-suppression of the partition function with a certain twisted boundary condition, and we utilize this idea for these criteria. With these definitions, we show that the center-vortex condensation requires the monopole condensation if the system is gapped and respects locality.

Studying (quasi-)hydrodynamics in holography: 

a simple application to Maxwell-Cattaneo model

Masataka Matsumoto (Chuo U.)
Room 907 (16:00-18:00)

Abstract: Holographic methods have historically provided powerful tools for describing the hydrodynamics of strongly correlated systems. In some situations, however, not only hydrodynamic modes but also non-hydrodynamic modes need to be carefully considered even in a low energy regime, and the framework for such situations is called quasi-hydrodynamics. In this talk, I will review the basic concepts for studying hydrodynamics via holography, and then discuss a simple application to the Maxwell-Cattaneo model based on our recent work.
