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…
Spin high-harmonic generation through terahertz laser-driven phonons
Negin Moharrami Allafi, Michael H. Kolodrubetz, Marin Bukov +2
In the realm of open quantum systems, steady states and high-harmonic generation (HHG) existing far from equilibrium have become core pillars of ultrafast science. Most solid-state…
Zeno physics of the Ising chain with symmetry-breaking boundary dephasing
Umar Javed, Riccardo J. Valencia-Tortora, Jamir Marino +2
In few-qubit systems, the quantum Zeno effect arises when measurement occurs sufficiently frequently that the spins are unable to relax between measurements. This can compete with…
Two entanglement conditions and their connection to negativity
Mark Hillery, Camilla Polvara, Vadim Oganesyan +1
We examine two conditions that can be used to detect bipartite entanglement, and show that they can be used to provide lower bounds on the negativity of states. We begin with two-q…
