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…
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…
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…
Trapping Hard-Core Bosons in Flatband Lattices
Sanghoon Lee, Alexei Andreanov, Tigran Sedrakyan +1
We investigate 1D and 2D cross-stitch lattices with hard-core bosons and analytically construct exact groundstates that feature macroscopic degeneracy. The construction relies on t…
