Optimal compression of constrained quantum time evolution
Maurits S. J. Tepaske, David J. Luitz, Dominik Hahn
The time evolution of quantum many-body systems is one of the most promising applications for near-term quantum computers. However, the utility of current quantum devices is strong…
Eigenstate correlations, the eigenstate thermalization hypothesis, and quantum information dynamics in chaotic many-body quantum systems
Dominik Hahn, David J. Luitz, J. T. Chalker
We consider the statistical properties of eigenstates of the time-evolution operator in chaotic many-body quantum systems. Our focus is on correlations between eigenstates that are…
Beyond Fermi's golden rule with the statistical Jacobi approximation
David M. Long, Dominik Hahn, Marin Bukov +1
Many problems in quantum dynamics can be cast as the decay of a single quantum state into a continuum. The time-dependent overlap with the initial state, called the fidelity, chara…
Quantum many-body Jarzynski equality and dissipative noise on a digital quantum computer
Dominik Hahn, Maxime Dupont, Markus Schmitt +2
The quantum Jarzynski equality and the Crooks relation are fundamental laws connecting equilibrium processes with nonequilibrium fluctuations. They are promising tools to benchmark…
Optimal compression of quantum many-body time evolution operators into brickwall circuits
Maurits S. J. Tepaske, Dominik Hahn, David J. Luitz
Near term quantum computers suffer from a degree of decoherence which is prohibitive for high fidelity simulations with deep circuits. An economical use of circuit depth is therefo…
Information Dynamics in a Model with Hilbert Space Fragmentation
Dominik Hahn, Paul A. McClarty, David J. Luitz
The fully frustrated ladder - a quasi-1D geometrically frustrated spin one half Heisenberg model - is non-integrable with local conserved quantities on rungs of the ladder, inducin…
Ergodic and non-ergodic many-body dynamics in strongly nonlinear lattices
Dominik Hahn, Juan-Diego Urbina, Klaus Richter +2
The study of non-linear oscillator chains in classical many-body dynamics has a storied history going back to the seminal work of Fermi, Pasta, Ulam and Tsingou (FPUT). We introduc…
