Decoupling band topology from criticality in bosonic systems
Mariam Ughrelidze, Lorenza Viola, Emilio Cobanera
A new understanding of criticality in systems described by quadratic bosonic Hamiltonians (QBHs) ties the emergence of long-range correlations to boundaries of dynamical, not therm…
Quantum criticality beyond thermodynamic stability
Mariam Ughrelidze, Vincent P. Flynn, Emilio Cobanera +1
For a many-body system in equilibrium, described by a thermodynamically stable Hamiltonian, quantum criticality is associated with structural changes of the many-body ground state.…
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-…
