Model States for a Class of Chiral Topological Order Interfaces

V. Crépel, N. Claussen, B. Estienne +1

Interfaces between topologically distinct phases of matter reveal a remarkably rich phenomenology. To go beyond effective field theories, we study the prototypical example of such…

Entanglement entropy and Berezin-Toeplitz operators

L. Charles, B. Estienne

We consider Berezin-Toeplitz operators on compact Kahler manifolds whose symbols are characteristic functions. When the support of the characteristic function has a smooth boundary…

Fractional Quantum Hall Matrix Product States For Interacting Conformal Field Theories

B. Estienne, N. Regnault, B. A. Bernevig

Using truncated conformal field theory (CFT), we present the formalism necessary to obtain exact matrix product state (MPS) representations for any fractional quantum hall model st…

Ideal Chern bands are Landau levels in curved space

B. Estienne, N. Regnault, V. Crépel

We prove that all the criteria proposed in the literature to identify a Chern band hosting exact fractional Chern insulating ground states, in fact, describe an equivalence with a…

On the particle entanglement spectrum of the Laughlin states

B. Majidzadeh Garjani, B. Estienne, E. Ardonne

The study of the entanglement entropy and entanglement spectrum has proven to be very fruitful in identifying topological phases of matter. Typically, one performs numerical studie…

Matrix product state representation of non-Abelian quasiholes

Yang-Le Wu, B. Estienne, N. Regnault +1

We provide a detailed explanation of the formalism necessary to construct matrix product states for non-Abelian quasiholes in fractional quantum Hall model states. Our construction…
