Quantum criticality in interacting bosonic Kitaev-Hubbard models
Ya-Nan Wang, Wen-Long You, Gaoyong Sun
Motivated by recent work on the non-Hermitian skin effect in the bosonic Kitaev-Majorana model, we study the quantum criticality of interacting bosonic Kitaev-Hubbard models on a c…
Topological phases of spinless -orbital fermions in zigzag optical lattices
Gaoyong Sun, Wen-Long You, Tao Zhou
Motivated by the experiment [St-Jean {\it et al}., Nature Photon. {\bf 11}, 651 (2017)] on topological phases with collective photon modes in a zigzag chain of polariton micropilla…
Fidelity and criticality of quantum Ising chain with long-range interactions
Zhangqi Zhu, Gaoyong Sun, Wen-Long You +1
We study the criticality of long-range quantum ferromagnetic Ising chain with algebraically decaying interactions via the fidelity susceptibility based on the exact diagona…
The optimal frequency window for Floquet engineering in optical lattices
Gaoyong Sun, André Eckardt
The concept of Floquet engineering is to subject a quantum system to time-periodic driving in such a way that it acquires interesting novel properties. It has been employed, for in…
Topological Phases of Fermionic Ladders with Periodic Magnetic Fields
Gaoyong Sun
In recent experiments bosonic [Atala et al., Nat. Phys. 10, 588 (2014), B. K. Stuhl et al., Science 349, 1514 (2015)] as well as fermionic ladders [M. Mancini et al., Science 349,…
Density-dependent synthetic magnetism for ultracold atoms in optical lattices
Sebastian Greschner, Daniel Huerga, Gaoyong Sun +2
Raman-assisted hopping can allow for the creation of density-dependent synthetic magnetism for cold neutral gases in optical lattices. We show that the density-dependent fields lea…
Topological order-by-disorder in orbitally degenerate dipolar bosons in zig-zag lattice
G. Sun, T. Vekua
Spinor bosons offer conceptually simple picture of macroscopic quantum behavior of topological order-by-disorder: Paramagnetic state of two-component dipolar bosons in orbitally de…
Density-Dependent Synthetic Gauge Fields Using Periodically Modulated Interactions
S. Greschner, G. Sun, D. Poletti +1
We show that density-dependent synthetic gauge fields may be engineered by combining periodically modu- lated interactions and Raman-assisted hopping in spin-dependent optical latt…
Spin-orbit coupled fermions in ladder-like optical lattices at half-filling
G. Sun, J. Jaramillo, L. Santos +1
We study the ground-state phase diagram of two-component fermions loaded in a ladder-like lattice at half filling in the presence of spin-orbit coupling. For repulsive fermions wit…
