Physics of higher orbital bands in optical lattices: a review
Xiaopeng Li, W. Vincent Liu
Orbital degree of freedom plays a fundamental role in understanding the unconventional properties in solid state materials. Experimental progress in quantum atomic gases has demons…
Exponential Orthogonality Catastrophe in Single-Particle and Many-Body Localized Systems
Dong-Ling Deng, J. H. Pixley, Xiaopeng Li +1
We investigate the statistical orthogonality catastrophe (StOC) in single-particle and many-body localized systems by studying the response of the many-body ground state to a local…
Detecting -phase superfluids with -wave symmetry in a quasi-1D optical lattice
Bo Liu, Xiaopeng Li, Randall G. Hulet +1
We propose an experimental protocol to study -wave superfluidity in a spin-polarized cold Fermi gas tuned by an -wave Feshbach resonance. A crucial ingredient is to add a qua…
Orbital hybridized topological Fulde-Ferrel superfluidity in a noncentrosymmetric optical lattice
Bo Liu, Xiaopeng Li, W. Vincent Liu
Topological phases like topological insulators or superconductors are fascinating quantum states of matter, featuring novel properties such as emergent chiral edge states or Majora…
Many body localization and quantum non-ergodicity in a model with a single-particle mobility edge
Xiaopeng Li, Sriram Ganeshan, J. H. Pixley +1
We investigate many body localization in the presence of a single particle mobility edge. By considering an interacting deterministic model with an incommensurate potential in one…
Exotic topological density waves in cold atomic Rydberg fermions
Xiaopeng Li, S. Das Sarma
Versatile controllability of interactions in ultracold atomic and molecular gases has now reached an unprecedented era where quantum correlations and unconventional many-body phase…
