Topological edge states in two-dimensional Potts paramagnet protected by the symmetry
Hrant Topchyan, Tigran Hakobyan, Mkhitar Mirumyan +2
We construct a two-dimensional bosonic symmetry-protected topological (SPT) paramagnet protected by an on-site symmetry, starting from a three-component…
Spontaneous Symmetry Breaking in Chiral Current-Carrying High-Energy Eigenstates
Tigran A. Sedrakyan, Jun-Jun Pang, Chenan Wei +1
Typical finite-energy-density eigenstates of nonintegrable systems are expected to obey the eigenstate thermalization hypothesis and to reproduce thermal local observables. In inte…
Nucleation of Sachdev-Ye-Kitaev Clusters in One Spatial Dimension
Hrant Topchyan, Tigran A. Sedrakyan
We study how Sachdev-Ye-Kitaev (SYK) interactions can arise from localized single-particle states on a system that is effectively one dimensional. If a local interaction is project…
Nonequilibrium from Equilibrium: Chiral Current-Carrying States in the Spin-1 Babujian-Takhtajan Chain
Bahar Jafari-Zadeh, Chenan Wei, Hrachya M. Babujian +1
We study the spin- Babujian-Takhtajan chain deformed by its third conserved charge . We derive and show that it is a dimensionless energy current and that its local d…
Chiral vortex-line liquid of three-dimensional interacting Bose systems with moat dispersion
Bahar Jafari-Zadeh, Chenan Wei, Tigran A. Sedrakyan
We formulate and investigate a novel quantum state, the Chiral Vortex-Line Liquid (CVLL), emerging in three-dimensional interacting Bose systems exhibiting moat-band dispersions. S…
Two-dimensional topological paramagnets protected by symmetry: Properties of the boundary Hamiltonian
Hrant Topchyan, Vasilii Iugov, Mkhitar Mirumyan +3
We systematically study gapless edge modes corresponding to symmetry-protected topological (SPT) phases of two-dimensional three-state Potts paramagnets on a triangu…
