Exact solution of a anisotropic spin chain with antiperiodic boundary condition
Yi Qiao, Jian Wang, Junpeng Cao +1
The exact solution of an integrable anisotropic Heisenberg spin chain with nearest-neighbour, next-nearest-neighbour and scalar chirality couplings is studied, where the boundary c…
Spectra of the Dissipative Spin Chain
Jian Wang, Sudip Chakravarty
This paper generalizes the (0+1)-dimensional spin-boson problem to the corresponding (1+1)-dimensional version. Monte Carlo simulation is used to find the phase diagram and imagina…
Rational function regression method for numerical analytic continuation
Jian Wang, Sudip Chakravarty
A simple method for numerical analytic continuation is developed. It is designed to analytically continue the imaginary time (Matsubara frequency) quantum Monte Carlo simulation re…
Binary disorder in quantum Ising chains and induced Majorana zero modes
Jian Wang, Sudip Chakravarty
Dynamical structure factor (S(k,)) is calculated for the one-dimensional (1D) transverse field Ising model, and its recent extension to include a three spin term, with quenched…
