Coherent forward scattering in 2D disordered systems
S. Ghosh, N. Cherroret, B. Grémaud +2
We present a detailed numerical and theoretical analysis of the recently discovered phenomenon of coherent forward scattering. This effect manifests itself as a macroscopic interfe…
Half-skyrmion and meron pair in spinor condensates
Yu-Xin Hu, Christian Miniatura, Benoît Grémaud
We propose a simple experimental scheme to generate spin textures in the ground state of interacting ultracold bosonic atoms loaded in a two-dimensional harmonic trap. Our scheme i…
Competing phases, phase separation and co-existence in the extended one-dimensional bosonic Hubbard model
G. G. Batrouni, V. G. Rousseau, R. T. Scalettar +1
We study the phase diagram of the one-dimensional bosonic Hubbard model with contact () and near neighbor () interactions focusing on the gapped Haldane insulating (HI) phase…
Dynamics of localized waves in 1D random potentials: statistical theory of the coherent forward scattering peak
Kean Loon Lee, Benoît Grémaud, Christian Miniatura
As recently discovered [PRL 190601(2012)], Anderson localization in a bulk disordered system triggers the emergence of a coherent forward scattering (CFS) peak in momen…
Superconducting Transitions in Flat Band Systems
V. I. Iglovikov, F. Hébert, B. Grémaud +2
The physics of strongly correlated quantum particles within a flat band was originally explored as a route to itinerant ferromagnetism and, indeed, a celebrated theorem by Lieb rig…
U(3) artificial gauge fields for cold atoms
Yu-Xin Hu, Christian Miniatura, David Wilkowski +1
We propose to generate an artificial non-Abelian gauge field by using a 2-tripod scheme, namely two tripod configurations sharing a common ground state level and driven by r…
