Solving multiorbital dynamical mean-field theory using natural orbitals renormalization group
Jia-Ming Wang, Yin Chen, Yi-Heng Tian +2
The natural orbitals renormalization group (NORG) has previously been proposed as an efficient numerical method for solving zero-temperature properties of multisite and multiorbita…
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…
Quantum Many-Body Calculations using Body-Centered Cubic Lattices
Young-Ho Song, Youngman Kim, Ning Li +3
It is often computationally advantageous to model space as a discrete set of points forming a lattice grid. This technique is particularly useful for computationally difficult prob…
Superfluid Condensate Fraction and Pairing Wave Function of the Unitary Fermi Gas
Rongzheng He, Ning Li, Bing-Nan Lu +1
The unitary Fermi gas is a many-body system of two-component fermions with zero-range interactions tuned to infinite scattering length. Despite much activity and interest in unitar…
