Chiral gapped states are universally non-topological
Xiang Li, Ting-Chun Lin, Yahya Alavirad +1
We propose an operator generalization of the Li-Haldane conjecture regarding the entanglement Hamiltonian of a disk in a 2+1D chiral gapped groundstate. The logic applies to region…
Irreducible multi-partite correlations as an order parameter for k-local nontrivial states
Yahya Alavirad, Ali Lavasani
Geometrically nontrivial quantum states can be defined as states that cannot be prepared by a constant depth geometrically local unitary circuit starting from a product state. Howe…
Topological order and criticality in (2+1)D monitored random quantum circuits
Ali Lavasani, Yahya Alavirad, Maissam Barkeshli
It has recently been discovered that random quantum circuits provide an avenue to realize rich entanglement phase diagrams, which are hidden to standard expectation values of opera…
Measurement-induced topological entanglement transitions in symmetric random quantum circuits
Ali Lavasani, Yahya Alavirad, Maissam Barkeshli
We study a class of (1+1)D symmetric random quantum circuits with two competing types of measurements in addition to random unitary dynamics. The circuit exhibits a rich phase diag…
Anomalies and unnatural stability of multi-component Luttinger liquids in spin chains
Yahya Alavirad, Maissam Barkeshli
We study translationally invariant spin chains where each unit cell contains an -state projective representation of a internal symmetry, general…
Ferromagnetism and its stability from the one-magnon spectrum in twisted bilayer graphene
Yahya Alavirad, Jay D. Sau
We study ferromagnetism and its stability in twisted bilayer graphene. We work with a Hubbard-like interaction that corresponds to the screened Coulomb interaction in a well-define…
Almost linear Haldane pseudopotentials and emergent conformal block wave-functions in a Landau level
Yahya Alavirad
We consider a two dimensional (2D) model of particles interacting in a Landau level. We work in a finite disk geometry and take the particles to interact with a linearly decreasing…
Scrambling in the Dicke model
Yahya Alavirad, Ali Lavasani
The scrambling rate associated with the exponential growth of out-of-time-ordered correlators can be used to characterize quantum chaos. Here we use the Majorana Fermion repr…
Chiral supercurrent through a quantum Hall weak link
Yahya Alavirad, Junhyun Lee, Ze-Xun Lin +1
We use a microscopic model to calculate properties of the supercurrent carried by chiral edge states of a quantum Hall weak link. This "chiral" supercurrent is qualitatively distin…
Spin-orbit coupled bosons in one dimension: emergent gauge field and Lifshitz transition
William S. Cole, Junhyun Lee, Khan W. Mahmud +3
In the presence of strong spin-independent interactions and spin-orbit coupling, we show that the spinor Bose liquid confined to one spatial dimension undergoes an interaction- or…
parafermionic zero modes without Andreev backscattering from the fractional quantum Hall state
Yahya Alavirad, David Clarke, Amit Nag +1
Parafermionic zero modes are a novel set of excitations displaying non-Abelian statistics somewhat richer than that of Majorana modes. These modes are predicted to occur when nearb…
Global phase diagram of a three dimensional dirty topological superconductor
Bitan Roy, Yahya Alavirad, Jay D. Sau
We investigate the phase diagram of a three-dimensional, time-reversal symmetric topological superconductor in the presence of charge impurities and random -wave pairing. Combin…
Role of boundary conditions, topology and disorder in the chiral magnetic effect in Weyl semimetals
Yahya Alavirad, Jay D. Sau
Quantum field theory predicts Weyl semimetals to possess a peculiar response of the longitudinal current density to the application of a DC magnetic field. Such a response function…
