SUMMARY:Fermionic Entanglement Entropy from Nonequilibrium Work (Jonathan D’Emidio/ LPT / Seminar). - 10/05/2022\, 14H
DESCRIPTION:Jonathan D’Emidio (DIPC\, Saint-Sébastien) \nAbstract : Computing entanglement entropies in strongly interacting many-body systems in two or more dimensions is a notoriously difficult task. Recently\, however\, a Monte Carlo method based on Jarzynski’s nonequilibrium work equality has enabled highly efficient calculations in quantum spin systems [1]. I will show how this concept can be extended to determinental quantum Monte Carlo (DQMC) simulations of fermions\, based on the decomposition introduced by T. Grover [2]. Here the nonequilibrium method entirely avoids the severe limitations faced by existing DQMC techniques\, which manifest themselves quite differently from the spin case. As a benchmark study I will provide data from T=0 projector simulations of the honeycomb Hubbard model. \n\n[1] J. D’Emidio\, Entanglement Entropy from Nonequilibrium Work\, Phys. Rev.

SUMMARY:Electrolyte transport through Carbon Nanotubes : a theoretical study (Théo Hennequin / LPT / Seminar). - 17/05/2022\, 14H
DESCRIPTION:Théo Hennequin  (LPT) \nAbstract : \n\nElectrolyte transport through single nanopore is an active field of research since it can be applied to technologies as nanofiltration\, or osmotic energies. Carbon Nanotubes (CNT) are among the most promising types of nanopores due to their properties : very clean and hydrophobic surfaces\, interesting electrical properties\, and a large aspect ratio. \nIndeed\, recent experiments showed that the ionic conductivity through CNT was 3 or 4 order of magnitude higher than through other nanopores. This is currently explained by a large fluid slippage\, and a high surface charge. But the physical properties of water and ions confined in CNT are not well understood\, and I will present two phenomena that we expect to have a great impact on these properties : Dielectric and Born effects and the role of the electronic density of states in the charging of the CNT. \n\n\n
