Integrability of the fractional quantum Hall edge states
Yichen Hu, Biao Lian
We investigate the homogeneous chiral edge theory of the filling fractional quantum Hall state, which is parameterized by a Luttinger liquid velocity matrix and an electron…
Chiral Sachdev-Ye model: Integrability and chaos of anyons in 1+1d
Yichen Hu, Biao Lian
We construct and study a chiral Sachdev-Ye (SY) model consisting of chiral SU Wess-Zumino-Witten (WZW) models with current-current interactions among each other, which g…
Conserved Quantities from Entanglement Hamiltonian
Biao Lian
We show that the subregion entanglement Hamiltonians of excited eigenstates of a quantum many-body system are approximately linear combinations of subregionally (quasi)local approx…
TSTG I: Single-Particle and Many-Body Hamiltonians and Hidden Non-local Symmetries of Trilayer Moiré Systems with and without Displacement Field
Dumitru Călugăru, Fang Xie, Zhi-Da Song +3
We derive the Hamiltonian for trilayer moiré systems with the Coulomb interaction projected onto the bands near the charge neutrality point. Motivated by the latest experimental re…
