The operational foundations of PT-symmetric and quasi-Hermitian quantum theory
Abhijeet Alase, Salini Karuvade, Carlo Maria Scandolo
PT-symmetric quantum theory was originally proposed with the aim of extending standard quantum theory by relaxing the Hermiticity constraint on Hamiltonians. However, no such exten…
Generating and detecting topological phases with higher Chern number
Abhijeet Alase, David L. Feder
Topological phases with broken time-reversal symmetry and Chern number |C|>=2 are of fundamental interest, but it remains unclear how to engineer the desired topological Hamiltonia…
Squaring the fermion: The threefold way and the fate of zero modes
Qiao-Ru Xu, Vincent P. Flynn, Abhijeet Alase +3
We investigate topological properties and classification of mean-field theories of stable bosonic systems. Of the three standard classifying symmetries, only time-reversal represen…
Generalization of Bloch's theorem for arbitrary boundary conditions: Interfaces and topological surface band structure
Emilio Cobanera, Abhijeet Alase, Gerardo Ortiz +1
We describe a method for exactly diagonalizing clean -dimensional lattice systems of independent fermions subject to arbitrary boundary conditions in one direction, as well as s…
A generalization of Bloch's theorem for arbitrary boundary conditions: Theory
Abhijeet Alase, Emilio Cobanera, Gerardo Ortiz +1
We present a generalization of Bloch's theorem to finite-range lattice systems of independent fermions, in which translation symmetry is broken only by arbitrary boundary condition…
