Single-particle eigenstate thermalization in quantum-chaotic quadratic Hamiltonians
Patrycja Łydżba, Yicheng Zhang, Marcos Rigol +1
We study the matrix elements of local and nonlocal operators in the single-particle eigenstates of two paradigmatic quantum-chaotic quadratic Hamiltonians; the quadratic Sachdev-Ye…

Emergent eigenstate solution for generalized thermalization
Yicheng Zhang, Lev Vidmar, Marcos Rigol
Generalized thermalization is a process that occurs in integrable systems in which unitary dynamics, e.g., following a quantum quench, results in states in which observables after…
