The response to dynamical modulation of the optical lattice for fermions in the Hubbard model
Zhaoxin Xu, Simone Chiesa, Shuxiang Yang +5
Fermionic atoms in a periodic optical lattice provide a realization of the single-band Hubbard model. Using Quantum Monte Carlo simulations along with the Maximum Entropy Method, w…
Dynamical structure factor of random antiferromagnetic Heisenberg spin chains
Zhaoxin Xu, Heping Ying, Xin Wan
Combining quantum Monte Carlo simulations with the maximum entropy method, we study the dynamical structure factor of spin-1/2 antiferromagnetic Heisenberg chains with var…
Entanglement and quantum phase transition in quantum mixed spin chains
Shang-Bin Li, Zhao-Xing Xu, Jian-Hui Dai +1
The ground entanglement and thermal entanglement in quantum mixed spin chains consisting of two integer spins 1 and two half integer spins 1/2 arrayed as in a uni…
On effects of regular S=1 dilution of S=1/2 antiferromagnetic Heisenberg chains by a quantum Monte Carlo simulation
Fengping Jin, Zhaoxin Xu, Heping Ying +1
The effects of regular S=1 dilution of S=1/2 isotropic antiferromagnetic chain are investigated by the quantum Monte Carlo loop/cluster algorithm. Our numerical results show that t…
Quantum Monte Carlo Simulations on S=1/2 antiferromagnetic-Ferromagnetic Random Alternating spin chain
Peng Zhang, Zhaoxin Xu, Heping Ying +1
The S=1/2 Heisenberg chain with bond alternation and randomness of antiferromagnetic (AFM) and ferromagnetic (FM) interactions is investigated by quantum Monte Carlo simulations of…
