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…

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…
