Exact solution of corner-modified banded block-Toeplitz eigensystems
Emilio Cobanera, Abhijeet Alase, Gerardo Ortiz +1
Motivated by the challenge of seeking a rigorous foundation for the bulk-boundary correspondence for free fermions, we introduce an algorithm for determining exactly the spectrum a…
Quantum Brownian motion in a Landau level
Emilio Cobanera, Peter Kristel, Cristiane Morais Smith
Motivated by questions about the open-system dynamics of topological quantum matter, we investigated the quantum Brownian motion of an electron in a homogeneous magnetic field. Whe…
What is a particle-conserving Topological Superfluid?
Gerardo Ortiz, Emilio Cobanera
We establish a criterion for characterizing superfluidity in interacting, particle-number conserving systems of fermions as topologically trivial or non-trivial. Because our criter…
Exact Solution of Quadratic Fermionic Hamiltonians for Arbitrary Boundary Conditions
Abhijeet Alase, Emilio Cobanera, Gerardo Ortiz +1
We present a procedure for exactly diagonalizing finite-range quadratic fermionic Hamiltonians with arbitrary boundary conditions in one of D dimensions, and periodic in the remain…
Thermodynamic signatures of edge states in topological insulators
Anton Quelle, Emilio Cobanera, Cristiane Morais Smith
Topological insulators are states of matter distinguished by the presence of symmetry protected metallic boundary states. These edge modes have been characterised in terms of trans…
