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…
Gradually opening Schrödinger's box reveals a cascade of sharp dynamical transitions
Barkay Guttel, Danielle Gov, Noam Netzer +9
Quantum mechanics predicts that unobserved systems may exist in a superposition of states, yet measurement produces definite outcomes, a tension at the heart of the quantum-to-clas…
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…
General theory of slow non-Hermitian evolution
Parveen Kumar, Yuval Gefen, Kyrylo Snizhko
Non-Hermitian systems are widespread in both classical and quantum physics. The dynamics of such systems has recently become a focal point of research, showcasing surprising behavi…
