Detecting a long lived false vacuum with quantum quenches
Gianluca Lagnese, Federica Maria Surace, Sid Morampudi +1
Distinguishing whether a system supports alternate low-energy (locally stable) states -- stable (true vacuum) versus metastable (false vacuum) -- by direct observation can be diffi…
Hamiltonian Dynamics of a Sum of Interacting Random Matrices
Matteo Bellitti, Siddhardh Morampudi, Chris R. Laumann
In ergodic quantum systems, physical observables have a non-relaxing component if they "overlap" with a conserved quantity. In interacting microscopic models, how to isolate the no…
Many-body systems with random spatially local interactions
Siddhardh C. Morampudi, Chris R. Laumann
We extend random matrix theory to consider randomly interacting spin systems with spatial locality. We develop several methods by which arbitrary correlators may be systematically…
