Anderson localization: A view from Krylov space
J. Clayton Peacock, Vadim Oganesyan, Dries Sels
The Krylov subspace expansion is a workhorse method for sparse numerics that has been increasingly explored as source of physical insight into many-body dynamics in recent years. I…

Effects of non-integrability in a non-Hermitian time crystal
Weihua Xie, Michael Kolodrubetz, Vadim Oganesyan +1
Time crystals are systems that spontaneously break time-translation symmetry, exhibiting repeating patterns in time. Recent work has shown that non-Hermitian Floquet systems can ho…

Effect of noise on quantum circuit realization of non-Hermitian time crystals
Weihua Xie, Michael Kolodrubetz, Vadim Oganesyan
Non-Hermitian quantum dynamics lie in an intermediate regime between unitary Hamiltonian dynamics and trace-preserving non-unitary open quantum system dynamics. Given differences i…
