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…
Restoring number conservation in quadratic bosonic Hamiltonians with dualities
Vincent P. Flynn, Emilio Cobanera, Lorenza Viola
Number-non-conserving terms in quadratic bosonic Hamiltonians can induce unwanted dynamical instabilities. By exploiting the pseudo-Hermitian structure built in to these Hamiltonia…
Deconstructing effective non-Hermitian dynamics in quadratic bosonic Hamiltonians
Vincent P. Flynn, Emilio Cobanera, Lorenza Viola
Unlike their fermionic counterparts, the dynamics of Hermitian quadratic bosonic Hamiltonians are governed by a generally non-Hermitian Bogoliubov-de Gennes effective Hamiltonian.…
