Exponential Speedup of Entanglement Generation by Quantum Mpemba Effects
Sara M. Benjadi, Reinhold Egger, Igor Gornyi +1
Entanglement is a key resource for quantum technologies. We show that protocols employing quantum Mpemba effects allow one to exponentially accelerate the generation of entanglemen…
Anisotropic magnetoresistance of 2D Rashba films with in-plane Zeeman field and short-range disorder
Igor Gornyi, Alexander Khaetskii
We study the dc conductivity of a continuum two-dimensional Rashba film with an in-plane Zeeman field and delta-correlated scalar disorder. Although the field deforms the two helic…
Interference of local-measurement histories
Parveen Kumar, Igor V. Gornyi, Yuval Gefen
The evolution of a quantum system comprises two fundamental processes--continuous unitary dynamics and stochastic measurement-induced jumps. The latter are often viewed as a source…
Universal cooling of quantum systems via randomized measurements
Josias Langbehn, George Mouloudakis, Emma King +5
Designing cooling protocols is believed to require knowledge of the system spectrum. In contrast, cooling in nature occurs whenever the system is coupled to a cold bath. How does n…
Generation of Volume-Law Entanglement by Local-Measurement-Only Quantum Dynamics
Surajit Bera, Igor V. Gornyi, Sumilan Banerjee +1
Repeated local measurements typically have adversarial effects on entangling unitary dynamics, as local measurements usually degrade entanglement. However, recent works on measurem…
Information transport and transport-induced entanglement in open fermion chains
Andrea Nava, Claudia Artiaco, Yuval Gefen +4
Understanding the entanglement dynamics in quantum many-body systems under steady-state transport conditions is an actively pursued challenging topic. Hydrodynamic equations, akin…
