Non-Hermitian Haldane-Hubbard model: Effective description of one- and two-body dissipation
Can Wang, Tian-Cheng Yi, Jian Li +1
Using numerically exact diagonalization, we study the correlated Haldane-Hubbard model in the presence of dissipation. Such dissipation can be modeled at short times by the dynamic…
Higher-order topological insulator in a modified Haldane-Hubbard model
Tian-Cheng Yi, Hai-Qing Lin, Rubem Mondaini
We investigate the ground-state phase diagram of a modified spinless Haldane-Hubbard model with broken threefold rotational symmetry, employing exact diagonalization calculations.…
Hamming Distance and the onset of quantum criticality
Tian-Cheng Yi, Richard T. Scalettar, Rubem Mondaini
Simulating models for quantum correlated matter unveils the inherent limitations of deterministic classical computations. In particular, in the case of quantum Monte Carlo methods,…
Interplay of interactions, disorder and topology in the Haldane-Hubbard model
Tian-Cheng Yi, Shijie Hu, Eduardo V. Castro +1
We investigate the ground-state phase diagram of the spinless Haldane-Hubbard model in the presence of quenched disorder, contrasting results obtained from both exact diagonalizati…
Lifshitz phase transitions in one-dimensional Gamma model
Zi-An Liu, Tian-Cheng Yi, Jin-Hua Sun +2
In this paper, we study quantum phase transitions and magnetic properties of a one-dimensional spin-1/2 Gamma model, which describes the off-diagonal exchange interactions between…
Criticality and factorization in the Heisenberg chain with Dzyaloshinskii-Moriya interaction
Tian-Cheng Yi, Wen-Long You, Ning Wu +1
In this work, we address the ground state properties of the anisotropic spin-1/2 Heisenberg XYZ chain under the interplay of magnetic fields and the Dzyaloshinskii-Moriya (DM) inte…
Quantum coherence in a compass chain under an alternating magnetic field
Wen-Long You, Yimin Wang, Tian-Cheng Yi +2
We investigate quantum phase transitions and quantum coherence in a quantum compass chain under an alternating transverse magnetic field. The model can be analytically solved by th…
Dynamical patterns of phase transformations from self-trapping of quantum excitons
Tianyou Yi, Natasha Kirova, Serguei Brazovskii
Phase transitions induced by short optical pulses is a new mainstream in studies of cooperative electronic states. Its special realization in systems with neutral-ionic transformat…
Modeling of dislocations in a CDW junction: interference of the CDW and the normal carriers
Alvaro Rojo Bravo, Tianyou Yi, Natasha Kirova +1
We derive and study equations for dissipative transient processes in a constraint incommensurate charge density wave (CDW) with remnant pockets or a thermal population of normal ca…
Multi-vortex dynamics in junctions of charge density waves
T. Yi, A. Rojo-Bravo, N. Kirova +1
Ground state reconstruction by creation of topological defects in junctions of CDWs is a convenient playground for modern efforts of field-effect transformations in strongly correl…
