Microcanonical Truncations of Observables in Quantum Chaotic Systems
Fernando Iniguez, Mark Srednicki
We consider the properties of an observable (such as a single spin component that squares to the identity) when expressed as a matrix in the basis of energy eigenstates, and then t…
Quantum Fisher Information for Different States and Processes in Quantum Chaotic Systems
Fernando Iniguez, Mark Srednicki
The quantum Fisher information (QFI) associated with a particular process applied to a many-body quantum system has been suggested as a diagnostic for the nature of the system's qu…
Entanglement Negativity Transitions in Chaotic Eigenstates
Sean McBride, Fernando Iniguez
It was recently noted that the entanglement entropy for a subsystem of a chaotic eigenstate exhibits an enhanced correction when the subsystem approaches a phase transition at half…
Non-Abelian eigenstate thermalization hypothesis
Chaitanya Murthy, Arman Babakhani, Fernando Iniguez +2
The eigenstate thermalization hypothesis (ETH) explains why chaotic quantum many-body systems thermalize internally if the Hamiltonian lacks symmetries. If the Hamiltonian conserve…
