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…
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…
