Anderson localization of Bogoliubov excitations on quasi-1D strips
Christopher Gaul, Pierre Lugan, Cord A. Müller
Anderson localization of Bogoliubov excitations is studied for disordered lattice Bose gases in planar quasi-one-dimensional geometries. The inverse localization length is computed…
Extracting partial decay rates of helium from complex rotation: autoionizing resonances of the one-dimensional configurations
Klaus Zimmermann, Pierre Lugan, Felix Jörder +5
Partial autoionization rates of doubly excited one-dimensional helium in the collinear Zee and eZe configuration are obtained by means of the complex rotation method. The approach…
Superfluid-insulator transition of two-dimensional disordered Bose gases
Joseph Saliba, Pierre Lugan, Vincenzo Savona
We study the two-dimensional weakly repulsive Bose gas at zero temperature in the presence of correlated disorder. Using large-scale simulations, we show that the low-energy Bogoli…
Superfluid-insulator transition in weakly interacting disordered Bose gases: a kernel polynomial approach
Joseph Saliba, Pierre Lugan, Vincenzo Savona
An iterative scheme based on the kernel polynomial method is devised for the efficient computation of the one-body density matrix of weakly interacting Bose gases within Bogoliubov…
Localization of Bogoliubov quasiparticles in interacting Bose gases with correlated disorder
Pierre Lugan, Laurent Sanchez-Palencia
We study the Anderson localization of Bogoliubov quasiparticles (elementary many-body excitations) in a weakly interacting Bose gas of chemical potential subjected to a disorde…
Localization of a matter wave packet in a disordered potential
Marie Piraud, Pierre Lugan, Philippe Bouyer +2
We theoretically study the Anderson localization of a matter wave packet in a one-dimensional disordered potential. We develop an analytical model which includes the initial phase-…
