Multispinon excitations in the spin S=1/2 antiferromagnetic Heisenberg model
Yu-Liang Liu
With the commutation relations of the spin operators, we first write out the equations of motion of the spin susceptibility and related correlation functions that have a hierarchic…
The analytical description of a doped Mott insulator
Yu-Liang Liu
With the hierarchical Green's function approach, we study a doped Mott insulator described with the Hubbard model by analytically solving the equations of motion of an one-particle…
The hierarchical Green function approach to the two-dimensional Hubbard model
Yu-Liang Liu
By introducing multipe-site correlation functions, we propose a hierarchical Green function approach, and apply it to study the characteristic properties of a 2D square lattice Hub…
Pure spin current and perfect valley filter by designed separation of the chiral states in two-dimensional honeycomb lattices
Da-Ping Liu, Zhi-Ming Yu, Yu-Liang Liu
We propose a realization of pure spin currents and perfect valley filter based on a quantum anomalous Hall insulator, around which edge states with up-spin and down-spin circulate.…
Comment on "Exact Classification of Landau-Majorana-Stuckelberg-Zener Resonances by Floquet Determinants"
Qing-Wei Wang, Yu-Liang Liu
In a recent Letter [S. Ganeshan, E. Barnes, and S. Das Sarma, Phys. Rev. Lett. 111, 130405 (2013)], Ganeshan et al. present a general framework to classify the resonance structure…
Comment on "Integrability of the Rabi Model"
Qing-Wei Wang, Yu-Liang Liu
Using Hill's determinant method we show that the set of Judd's solutions is only a subset of all the eigenvalues with the form in the spectrum of the Rabi model. The…
