Gradient corrections to the local density approximation in the one-dimensional Bose gas
François Riggio, Yannis Brun, Dragi Karevski +2
The local density approximation (LDA) is the central technical tool in the modeling of quantum gases in trapping potentials. It consists in treating the gas as an assembly of indep…
Conformal field theory on top of a breathing one-dimensional gas of hard core bosons
Paola Ruggiero, Yannis Brun, Jérome Dubail
The recent results of [J. Dubail, J.-M. Stéphan, J. Viti, P. Calabrese, Scipost Phys. 2, 002 (2017)], which aim at providing access to large scale correlation functions of inhomoge…
The Inhomogeneous Gaussian Free Field, with application to ground state correlations of trapped 1d Bose gases
Yannis Brun, Jérôme Dubail
Motivated by the calculation of correlation functions in inhomogeneous one-dimensional (1d) quantum systems, the 2d Inhomogeneous Gaussian Free Field (IGFF) is studied and solved.…
One-particle density matrix of trapped one-dimensional impenetrable bosons from conformal invariance
Yannis Brun, Jérôme Dubail
The one-particle density matrix of the one-dimensional Tonks-Girardeau gas with inhomogeneous density profile is calculated, thanks to a recent observation that relates this system…
