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…
