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…
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…
The Sachdev-Ye-Kitaev model and free Majorana variational states
Daniel Ish, Mark Srednicki
Through a mixture of analytic and numerical techniques, we explore the optimal approximation by a free Majorana state to individual disorder realizations of the Sachdev-Ye-Kitaev m…
Bounds on chaos from the eigenstate thermalization hypothesis
Chaitanya Murthy, Mark Srednicki
We show that the known bound on the growth rate of the out-of-time-order four-point correlator in chaotic many-body quantum systems follows directly from the general structure of o…
Structure of chaotic eigenstates and their entanglement entropy
Chaitanya Murthy, Mark Srednicki
We consider a chaotic many-body system (i.e., one that satisfies the eigenstate thermalization hypothesis) that is split into two subsystems, with an interaction along their mutual…
