Félix Werner (ENS, LKB) Seminar LPT, 19/09/2023, 14H, 3R1, seminar room, 3rd floor Summary : In contrast to conventional QMC methods, expansions of intensive quantities in series of connected Feynman diagrams can be formulated directly in the thermodynamic limit. Over the last decade, diagrammatic Monte Carlo algorithms made it possible to reach large expansion orders… Read More »High-order diagrammatic expansion around BCS Hamiltonians : Polarized superfluid phase of the attractive Hubbard model – (Félix Werner / LPT / Seminar). – 19/09/2023, 14H

Ludovic Jaubert (LOMA, Bordeaux) Seminar LPT, 17/10/2023, 14H, 3R1, seminar room, 3rd floor Summary : What we colloquially know about frustration, is that it prevents magnetic order. But the interesting part is not so much the absence of something, but rather what happens in its place. Frustration usually stems from one of only two elementary… Read More »A glimpse of the 4th dimension in a spin liquid – (Ludovic Jaubert / LPT / Seminar). – 17/10/2023, 14H

Doron Grossman (LPT) Seminar LPT, 7/11/2023, 14H, 3R1, seminar room, 3rd floor Summary : We present a covariant continuum formulation of a generalized two-dimensional vertexlike model of epithelial tissues which describes tissues with different underlying geometries, and allows for an analytical macroscopic description. Using a geometrical approach and out-of-equilibrium statistical mechanics, we calculate both mechanical… Read More »Instabilities and Geometry of Growing Tissues. – (Doron Grossman / LPT / Seminar). – 07/11/2023, 14 H.
