Reinforcement Learning to Harness Approximation Errors for Long-Time Quantum Simulation
Yu-Bo Shi, Markus Heyl, Roderich Moessner +2
Accurate digital quantum simulation at long times is limited by the accumulation of errors inherent to approximate simulation. Here we introduce RL-Trotter, a reinforcement-learnin…
Observation of far-from-equilibrium scaling in the transient dynamics of 2D quantum magnets
Fabio Bensch, Umberto Borla, Federico Balducci +7
The transient regime of far-from-equilibrium quantum many-body dynamics lacks the established organizing principles that universality and scaling provide in equilibrium. It is leas…
Fractal deconfinement and confinement in Sierpinski ice
James Walkling, Roderich Moessner
We study the six-vertex model on the Sierpinski gasket, a four-coordinated hierarchical fractal with Hausdorff dimension . Given the importance of dimensionality for t…
Validation and calibration of quantum hardware through the many-body quantum Mpemba effect
Francesco Campaioli, Marco Avesani, Oren Raz +2
We introduce a validation process that harnesses engineered many-body relaxation to control and calibrate quantum hardware. On two independently developed neutral-atom processors,…
Hydrodynamic Memory and Long-Time Tails in Clean Frustrated Magnets
Yufei Pei, Claudio Castelnovo, Roderich Moessner
In a simple, clean but constrained magnet, we identify a self-interacting random walk with memory. For the motion of a single monopole -- a fractionalized quasiparticle in spin ice…
Universal Dynamic Scaling of 2D Quantum Ising Transition on the Fuzzy Sphere
Meng Zeng, Shuai Yin, Roderich Moessner
We revisit the problem of \textit{real-time} quantum dynamics of the paradigmatic two dimensional transverse-field Ising model using the recently developed fuzzy sphere regularizat…
