Simulating hydrodynamics on noisy intermediate-scale quantum devices with random circuits
Jonas Richter, Arijeet Pal
In a recent milestone experiment, Google's processor Sycamore heralded the era of "quantum supremacy" by sampling from the output of (pseudo-)random circuits. We show that such ran…
Eigenstate thermalization hypothesis beyond standard indicators: Emergence of random-matrix behavior at small frequencies
Jonas Richter, Anatoly Dymarsky, Robin Steinigeweg +1
Using numerical exact diagonalization, we study matrix elements of a local spin operator in the eigenbasis of two different nonintegrable quantum spin chains. Our emphasis is on th…
Quantum quench dynamics in the transverse-field Ising model: A numerical expansion in linked rectangular clusters
Jonas Richter, Tjark Heitmann, Robin Steinigeweg
We study quantum quenches in the transverse-field Ising model defined on different lattice geometries such as chains, two- and three-leg ladders, and two-dimensional square lattice…
Density dynamics in the mass-imbalanced Hubbard chain
Tjark Heitmann, Jonas Richter, Thomas Dahm +1
We consider two mutually interacting fermionic particle species on a one-dimensional lattice and study how the mass ratio between the two species affects the (equilibration) dy…
Temporal relaxation of gapped many-body quantum systems
Peter Reimann, Ben N. Balz, Jonas Richter +1
Typicality of the orthogonal dynamics (TOD) is established as a generic feature of temporal relaxation processes in isolated many-body quantum systems. The basic idea in the simple…
Finite-size scaling of typicality-based estimates
J. Schnack, J. Richter, T. Heitmann +1
According to the concept of typicality, an ensemble average can be accurately approximated by an expectation value with respect to a single pure state drawn at random from a high-d…
Selected applications of typicality to real-time dynamics of quantum many-body systems
Tjark Heitmann, Jonas Richter, Dennis Schubert +1
Loosely speaking, the concept of quantum typicality refers to the fact that a single pure state can imitate the full statistical ensemble. This fact has given rise to a rather simp…
