SUMMARY:Quantum Coulomb glass on the Bethe lattice
DESCRIPTION:Featuring Izabella Lovas\, LMU\, Munich\n\nPart of the Biophysi
	cs/Condensed Matter Seminar Series.\n\nWe study the Coulomb glass emerging 
	from the interplay of strong interactions and disorder in a model of spinle
	ss fermions on the Bethe lattice\, in the limit of infinite coordination nu
	mber. By combining continuous time quantum Monte-Carlo simulations with sel
	f-consistent diagrammatic perturbation theory\, we find that strong interac
	tions induce a metallic Coulomb glass phase with a pseudogap structure at t
	he Fermi energy. Quantum and thermal fluctuations both melt this glass and 
	induce a disordered quantum liquid phase. We obtain the complete phase diag
	ram of the electron glass\, and characterize its dynamical properties in th
	e replica symmetric quantum liquid phase\, as well as in the glassy phase i
	n the presence of full replica symmetry breaking. The spectral function dis
	plays an Efros-Shklovskii pseudogap upon decreasing temperatures\, but the 
	density of states remains finite at the Fermi energy due to residual quantu
	m fluctuations. Our results bear relevance to the metallic glass phase obse
	rved in Si inversion layers.\n\nhttps://bostonu.zoom.us/j/98731662171?pwd=V
