Real-time Dynamics in 3D for up to 1000 Qubits with Neural Quantum States: Quenches and the Quantum Kibble--Zurek Mechanism
Vighnesh Dattatraya Naik, Zheng-Hang Sun, Markus Heyl
Exponential complexity of many-body wave functions limits accurate numerical simulations of real-time dynamics, especially beyond 1D, where rapid entanglement growth poses severe c…

Probing prethermal nonergodicity through measurement outcomes of monitored quantum dynamics
Zheng-Hang Sun, Fabian Ballar Trigueros, Qicheng Tang +1
Projective measurements are a key element in quantum physics and enable rich phenomena in monitored quantum dynamics. Here, we show that the measurement outcomes, recorded during m…

Probing quantum many-body dynamics using subsystem Loschmidt echos
Simon Karch, Souvik Bandyopadhyay, Zheng-Hang Sun +9
The Loschmidt echo - the probability of a quantum many-body system to return to its initial state following a dynamical evolution - generally contains key information about a quant…
