Entanglement spectroscopy on a quantum computer
Sonika Johri, Damian S. Steiger, Matthias Troyer
We present a quantum algorithm to compute the entanglement spectrum of arbitrary quantum states. The interesting universal part of the entanglement spectrum is typically contained…
Probing the geometry of the Laughlin state
Sonika Johri, Z. Papic, P. Schmitteckert +2
It has recently been pointed out that phases of matter with intrinsic topological order, like the fractional quantum Hall states, have an extra dynamical degree of freedom that cor…
Quasiholes of 1/3 and 7/3 quantum Hall states: size estimates via exact diagonalization and density-matrix renormalization group
Sonika Johri, Zlatko Papić, R. N. Bhatt +1
We determine the size of the elementary quasihole in and quantum Hall states via exact-diagonalization and density-matrix renormalization group calculations on the…
Comparison of the density-matrix renormalization group method applied to fractional quantum Hall systems in different geometries
Zi-Xiang Hu, Z. Papic, S. Johri +2
We report a systematic study of the fractional quantum Hall effect (FQHE) using the density-matrix renormalization group (DMRG) method on two different geometries: the sphere and t…
