Quantum simulation using noisy unitary circuits and measurements
Oliver Lunt, Jonas Richter, Arijeet Pal
Many-body quantum systems are notoriously hard to study theoretically due to the exponential growth of their Hilbert space. It is also challenging to probe the quantum correlations…
Eigenstate thermalization hypothesis and its deviations from random-matrix theory beyond the thermalization time
Jiaozi Wang, Mats H. Lamann, Jonas Richter +3
The Eigenstate Thermalization Hypothesis (ETH) explains emergence of the thermodynamic equilibrium by assuming a particular structure of observable's matrix elements in the energy…
Anomalous hydrodynamics in a class of scarred frustration-free Hamiltonians
Jonas Richter, Arijeet Pal
Atypical eigenstates in the form of quantum scars and fragmentation of Hilbert space due to conservation laws provide obstructions to thermalization in the absence of disorder. In…
Quantum versus Classical Dynamics in Spin Models: Chains, Ladders, and Square Lattices
Dennis Schubert, Jonas Richter, Fengping Jin +3
We present a comprehensive comparison of spin and energy dynamics in quantum and classical spin models on different geometries, ranging from one-dimensional chains, over quasi-one-…
Quantum scars and bulk coherence in a symmetry-protected topological phase
Jared Jeyaretnam, Jonas Richter, Arijeet Pal
Formation of quantum scars in many-body systems provides a novel mechanism for enhancing coherence of weakly entangled states. At the same time, coherence of edge modes in certain…
Nontrivial damping of quantum many-body dynamics
Tjark Heitmann, Jonas Richter, Jochen Gemmer +1
Understanding how the dynamics of a given quantum system with many degrees of freedom is altered by the presence of a generic perturbation is a notoriously difficult question. Rece…
