: An open-source quantum impurity solver package based on the natural orbitals renormalization group
Jia-Ming Wang, Yi-Heng Tian, Yin Chen +3
In the context of dynamical mean-field theory (DMFT) calculations for strongly correlated electron systems, quantum impurity solvers play a central computational role in treating c…
bands driven high-temperature superconductivity in hydrogenated hexagonal BC monolayer
Guo Chen, Ru Zheng, Jin-Hua Sun +5
Material with metallic -bonding bands is expected to be a high-temperature superconductor, due to the sensitivity of electrons to lattice vibration. Based on the first-princ…
Natural orbitals renormalization group approach to a spin-1/2 impurity interacting with two helical liquids
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
Using the natural orbitals renormalization group, we studied the problem of a localized spin- 1/2 impurity coupled to two helical liquids via the Kondo interaction in a quantum spi…
Magnetic correlation between two local spins in a quantum spin Hall insulator
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
Two spins located at the edge of a quantum spin Hall insulator may interact with each other via indirect spin-exchange interaction mediated by the helical edge states, namely the R…
An Anderson impurity interacting with the helical edge states in a quantum spin Hall insulator
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
Using the natural orbitals renormalization group (NORG) method, we have investigated the screening of the local spin of an Anderson impurity interacting with the helical edge state…
Order parameter for the multichannel Kondo model at quantum criticality
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
A multichannel Kondo model, where two or more equivalent but independent channels of electrons compete to screen a spin-1/2 impurity, shows overcompensation of the impurity spin, l…
Strain-mediated Symmetry Breaking Switch with Perpendicular Magnetic Anisotropy
Ruoda Zheng, Jin-Zhao Hu, Qianchang Wang +3
Magnetic switch with perpendicular magnetic anisotropy (PMA) is a promising method for controlling magnetization in several applications like magnetic tunnel junction and magnetic…
Natural orbitals renormalization group approach to a Kondo singlet
Ru Zheng, Rong-Qiang He, Zhong-Yi Lu
A magnetic impurity embedded in a metal host is collectively screened by a cloud of conduction electrons to form a Kondo singlet below a characteristic energy scale , the Kond…
Accurate expansions of internal energy and specific heat of critical two-dimensional Ising model with free boundaries
Xintian Wu, Ru Zheng, Nickolay Izmailian +1
The bond-propagation (BP) algorithm for the specific heat of the two dimensional Ising model is developed and that for the internal energy is completed. Using these algorithms, we…
