Breakdown of Multipole Expansion in Emergent Electromagnetism
Tom Ben-Ami, Markus Heyl, Roderich Moessner
We find a striking departure from simple electrostatics in a family of two-dimensional lattice models whose effective description takes the form of an emergent electromagnetism: a…
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…
Many-body cages: disorder-free glassiness from flat bands in Fock space, and many-body Rabi oscillations
Tom Ben-Ami, Markus Heyl, Roderich Moessner
We introduce many-body caging as a novel mechanism for nonthermal behaviour in quantum matter. We define many-body cages as eigenstates that, through quantum interference, become l…
Fractional diffusion without disorder in two dimensions
Nilotpal Chakraborty, Markus Heyl, Roderich Moessner
We analyse how simple local constraints in two dimensions lead a defect to exhibit robust, non-transient, and tunable, subdiffusion. We uncover a rich dynamical phenomenology reali…
Convolutional transformer wave functions
Ao Chen, Vighnesh Dattatraya Naik, Markus Heyl
Deep neural quantum states have recently achieved remarkable performance in solving challenging quantum many-body problems. While transformer networks appear particularly promising…
Learning effective Hamiltonians for adaptive time-evolution quantum algorithms
Hongzheng Zhao, Ao Chen, Shu-Wei Liu +3
Digital quantum simulation of many-body dynamics relies on Trotterization to decompose the target time evolution into elementary quantum gates operating at a fixed equidistant time…
Spectrum and low-temperature bulk properties of triangular quantum spin liquid candidate NaYbSe
A. O. Scheie, Minseong Lee, Kevin Wang +18
We report neutron scattering, pressure-dependent AC calorimetry, and AC magnetic susceptibility measurements of triangular lattice NaYbSe. We observe a continuum of scattering,…
Adaptive Trotterization for time-dependent Hamiltonian quantum dynamics using piecewise conservation laws
Hongzheng Zhao, Marin Bukov, Markus Heyl +1
Digital quantum simulation relies on Trotterization to discretize time evolution into elementary quantum gates. On current quantum processors with notable gate imperfections, there…
Finite-temperature critical behavior of long-range quantum Ising models
E. Gonzalez-Lazo, M. Heyl, M. Dalmonte +1
We study the phase diagram and critical properties of quantum Ising chains with long-range ferromagnetic interactions decaying in a power-law fashion with exponent , in regimes…
