Demonstration of a Tunable Non-Hermitian Nonlinear Microwave Dimer
Juan S. Salcedo-Gallo, Michiel Burgelman, Vincent P. Flynn +6
Achieving and controlling non-reciprocity in engineered photonic structures is of fundamental interest in science and engineering. Here, we introduce a tunable, non-Hermitian, nonl…
The Interplay of Finite and Infinite Size Stability in Quadratic Bosonic Lindbladians
Mariam Ughrelidze, Vincent P Flynn, Emilio Cobanera +1
We provide a framework for understanding dynamical metastability in open many-body systems of free bosons, whereby the dynamical stability properties of the system in the infinite-…
Topological zero modes and edge symmetries of metastable Markovian bosonic systems
Vincent P. Flynn, Emilio Cobanera, Lorenza Viola
Tight bosonic analogs of free-fermionic symmetry-protected topological phases, and their associated edge-localized excitations, have long evaded the grasp of condensed-matter and A…
Topology by Dissipation: Majorana Bosons in Metastable Quadratic Markovian Dynamics
Vincent P. Flynn, Emilio Cobanera, Lorenza Viola
Majorana bosons, that is, tight bosonic analogs of the Majorana fermionic quasiparticles of condensed matter physics, are forbidden for gapped free bosonic matter within a standard…
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.…
Exploring itinerant states in divalent hexaborides using rare-earth edge resonant inelastic X-ray scattering
Donal Sheets, Vincent Flynn, Jungho Kim +10
We present a study of resonant inelastic X-ray scattering (RIXS) spectra collected at the rare-earth edges of divalent hexaborides YbB and EuB. In both systems, RIXS-ac…
