Phases and Exotic Phase Transitions of a Two-Dimensional Su-Schrieffer-Heeger Model
Anika Götz, Martin Hohenadler, Fakher F. Assaad
We study a Su-Schrieffer-Heeger electron-phonon model on a square lattice by means of auxiliary-field quantum Monte Carlo simulations. The addition of a symmetry-allowed interactio…
Simulation of Fermionic and Bosonic Critical Points with Emergent SO(5) Symmetry
Toshihiro Sato, Zhenjiu Wang, Yuhai Liu +4
We introduce a model of Dirac fermions in 2+1 dimensions with a semimetallic, a quantum spin-Hall insulating (QSHI), and an s-wave superconducting (SSC) phase. The phase diagram fe…
Thermodynamic and Dynamical Signatures of a Quantum Spin-Hall Insulator to Superconductor Transition
Martin Hohenadler, Yuhai Liu, Toshihiro Sato +3
Thermodynamic and dynamical properties of a model of Dirac fermions with a deconfined quantum critical point (DQCP) separating an interaction-generated quantum spin-Hall insulator…
Valence-bond solid to antiferromagnet transition in the two-dimensional Su-Schrieffer-Heeger model by Langevin dynamics
Anika Götz, Stefan Beyl, Martin Hohenadler +1
The two-dimensional Su-Schrieffer-Heeger model of electrons coupled to quantum phonons is investigated using Langevin dynamics within the framework of auxiliary-field quantum Monte…
Doping-induced quantum spin Hall insulator to superconductor transition
Zhenjiu Wang, Yuhai Liu, Toshihiro Sato +4
A unique property of a dynamically generated quantum spin Hall state are Goldstone modes that correspond to the long-wavelength fluctuations of the spin-orbit coupling order parame…
Topological terms on topological defects: a quantum Monte Carlo study
Toshihiro Sato, Martin Hohenadler, Tarun Grover +2
Dirac fermions in dimensions with dynamically generated anticommuting SO(3) antiferromagnetic (AFM) and Z Kekulé valence-bond solid (KVBS) masses map onto a field theory…
