A semiclassical Hilbert space for random matrix theory
Abhirup Bhattacharya, Onkar Parrikar, Vivek Singh
We study the one-sided time evolution of thermofield double (TFD) states in random matrix theory, where the Hamiltonian is taken to be a random matrix drawn from a unit…
Stabilizer complexity and the Python's lunch
Abhirup Bhattacharya, Jatin Narde, Onkar Parrikar +1
In this note, we study the stabilizer complexity of the reduced density matrix corresponding to one side of a partially entangled thermal (PET) state with fixed energy boundary con…
Wigner negativity in Krylov space and emergent semiclassicality
Vijay Balasubramanian, Pawel Caputa, Onkar Parrikar +1
We propose that the Krylov basis gives a semiclassical representation of dynamics in general large-, complex, many-body systems. As a probe of this semiclassicality, we study th…
Fortuity and Complexity in a Simple Quark Model
Jackson R. Fliss, Vishnu Jejjala, Onkar Parrikar
We observe and elaborate on a structural similarity between the categorization of monotone and fortuitous BPS operators in supersymmetric theories and gauge invariant quark operato…
