Entanglement and Fidelity: Statics and Dynamics

PD Sacramento - Symmetry, 2023 - mdpi.com
Herein, aspects of entanglement and fidelity and their use in condensed matter systems are
briefly reviewed. Both static and time-dependent situations are considered. Different …

Defining a universal sign to strictly probe a phase transition

N Ma, JS Sun, G Pan, C Cheng, Z Yan - Physical Review B, 2024 - APS
The mystery of the infamous sign problem in quantum Monte Carlo simulations mightily
restricts applications of the method in fermionic and frustrated systems. A recent work …

Real-space parallel density matrix renormalization group with adaptive boundaries

FZ Chen, C Cheng, HG Luo - Chinese Physics B, 2021 - iopscience.iop.org
We propose an improved real-space parallel strategy for the density matrix renormalization
group (DMRG) method, where boundaries of separate regions are adaptively distributed …

Edge parafermions in fermionic lattices

RLRC Teixeira, LGGV Dias da Silva - Physical Review B, 2022 - APS
Parafermion modes are non-Abelian anyons which were introduced as ZN generalizations
of Z 2 Majorana states. In particular, Z 3 parafermions can be used to produce Fibonacci …

Enhanced superconductivity and various edge modes in modulated chains

YF Yang, J Chen, C Cheng, HG Luo - Physical Review B, 2022 - APS
We numerically investigate the ground state of the extended tJ Hamiltonian with periodic
local modulations in one dimension by using the density-matrix renormalization group …

[HTML][HTML] SPT extension of Z2 quantum Ising model's ferromagnetic phase

H Topchyan - Physics Letters A, 2024 - Elsevier
This paper focuses on the creation of a model with explicitly defined symmetry-protected
topological (SPT) phases on a triangular lattice as an extension of Z 2 Ising model's …

Parafermionic modes in correlated electron systems

RLRC Teixeira - 2023 - teses.usp.br
Obtaining non-abelian anyons is one of the primary goals within the field of topological
states of matter. The simplest of these anyons, Majorana bound states (MBSs), have been …

Generic Technique for Explicit Definition of Models with SPT Phases.

H Topchyan - Armenian Journal of Physics, 2023 - search.ebscohost.com
This paper focuses on creation of a technique to derive systems with explicitly defined
symmetry protected topological (SPT) phases on a triangular lattice, based on models …
