In this work, we develop a new variational finite-temperature algorithm (VAFT), which combines ideas from minimally entangled typical thermal states (METTS), variational Monte Carlo (VMC) optimization, and path integral Monte Carlo (PIMC). This allows us to define an implicit variational density matrix to estimate finite-temperature properties in two and three dimensions. We benc ... 14:00 - 15:00 Weekly SeminarCondensed Matter and Statistical Physics Group Active fluid at circular interfaces: pressure and current density School PHYSICS Farmanieh Seminar Room ... 14:00 - 15:00 Weekly SeminarActive fluid at circular interfaces: pressure and current density School NANO SCIENCES Active fluid at circular interfaces: pressure and current density+6We study the pressure exerted by an active fluid composed of non-interacting, non-aligning, chiral active Brownian particles on circular interfaces with both concave and convex curvature. Physical realizations include circular (disk-shaped) colloidal inclusions immersed in an active fluid and circular containers confining an active fluid, respectively. We solve the Fokker-Planck-Smoluchowski equation for the probability density of active particles using both analytical and numerical methods to find the active pressure exerted on such interfaces. We determine ... 15:30 - 16:30 Weekly SeminarSearches for Production of Third Generation Squarks at CMS School PARTICLES AND ACCELERATORS A report on searches for the pair production of third-generation squarks in proton-proton collision events with two-body decays to bottom, top or charm quarks and a neutralino, which produces a significant imbalance in the transverse momentum. The searches are performed using a sample of proton-proton collision data at ?s = 13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb ? 1 .
