Dynamics Investigation of the quantum-control-assisted multipartite uncertainty relation in Heisenberg model with Dzyaloshinski-Moriya interaction
Jie Xu, Xiao Zheng, Ai-Ling Ji +1
Recently, Zheng constructs a quantum-control-assisted multipartite variance-based uncertainty relation, which successfully extends the conditional uncertainty relation to the multi…
-tensor gradient flow with quasi-entropy and discretizations preserving physical constraints
Yanli Wang, Jie Xu
We propose and analyze numerical schemes for the gradient flow of -tensor with the quasi-entropy. The quasi-entropy is a strictly convex, rotationally invariant elementary funct…
Quasi-entropy by log-determinant covariance matrix and application to liquid crystals
Jie Xu
A quasi-entropy is constructed for tensors averaged by a density function on using the log-determinant of a covariance matrix. It serves as a substitution of the entropy fo…
Symmetry-consistent expansion of interaction kernels between rigid molecules
Jie Xu
We discuss the expansion of interaction kernels between anisotropic rigid molecules. The expansion decouples the correlated orientational variables so that it can be utilized to de…
Classifying local anisotropy formed by rigid molecules: symmetries and tensors
Jie Xu
We consider an infinitesimal volume where there are many rigid molecules of the same kind, and discuss the description and classification of the local anisotropy in this volume by…
CPMC-Lab: A Matlab Package for Constrained Path Monte Carlo Calculations
Huy Nguyen, Hao Shi, Jie Xu +1
We describe CPMC-Lab, a Matlab program for the constrained-path and phaseless auxiliary-field Monte Carlo methods. These methods have allowed applications ranging from the study of…
Perturbation Methods for Non-Markovian Quantum State Diffusion Equation
Jie Xu, Xinyu Zhao, Jun Jing +2
Two perturbation methods for the non-Markovian quantum state diffusion (NMQSD) equation are investigated. The first perturbation method under investigation is based on a functional…
Magnetic order in the repulsive Fermi-Hubbard model in three-dimensions and the crossover to two-dimensions
Jie Xu, Simone Chiesa, Eric J. Walter +1
Systems of fermions described by the three-dimensional (3D) repulsive Hubbard model on a cubic lattice have recently attracted considerable attention due to their possible experime…
Spin- and charge-density waves in the Hartree-Fock ground state of the two-dimensional Hubbard model
Jie Xu, Chia-Chen Chang, Eric J. Walter +1
The ground states of the two-dimensional repulsive Hubbard model are studied within the unrestricted Hartree-Fock (UHF) theory. Magnetic and charge properties are determined by sys…
Qubit Entanglement Dephasing Dynamics Driven by a Bath of Spins
Jie Xu, Jun Jing, Ting Yu
We study the entanglement dynamics for a two-spin system coupled to a spin environment of different configurations by z-x type interaction. The models considered in this paper are…
