A momentum dependent optical lattice induced by artificial gauge potential
Zekai Chen, Hepeng Yao, Elisha Haber +1
We propose an experimentally feasible method to generate a one-dimensional optical lattice potential in an ultracold Bose gas system that depends on the transverse momentum of the…
Strongly-Interacting Bosons in a Two-Dimensional Quasicrystal Lattice
Ronan Gautier, Hepeng Yao, Laurent Sanchez-Palencia
Quasicrystals exhibit exotic properties inherited from the self-similarity of their long-range ordered, yet aperiodic, structure. The recent realization of optical quasicrystal lat…
One dimensional quasiperiodic mosaic lattice with exact mobility edges
Yucheng Wang, Xu Xia, Long Zhang +5
The mobility edges (MEs) in energy which separate extended and localized states are a central concept in understanding the localization physics. In one-dimensional (1D) quasiperiod…
Lieb-Liniger Bosons in a Shallow Quasiperiodic Potential: Bose Glass Phase and Fractal Mott Lobes
Hepeng Yao, Thierry Giamarchi, Laurent Sanchez-Palencia
The emergence of a compressible insulator phase, known as the Bose glass, is characteristic of the interplay of interactions and disorder in correlated Bose fluids. While widely st…
Tan's Contact for Trapped Lieb-Liniger Bosons at Finite Temperature
Hepeng Yao, David Clément, Anna Minguzzi +2
The universal Tan relations connect a variety of microscopic features of many-body quantum systems with two-body contact interactions to a single quantity, called the contact. The…
