Extracting the physical content of Liouvillian eigenmodes: Semiclassical quantization
Ashlin V Thomas, Felix Fritzsch, Masudul Haque +1
Unlike in closed quantum systems where individual energy eigenstates are understood as physical excitations, open quantum systems have distinct right and left eigenstates of the Li…
Information in Many-body Eigenstates: A Question of Learnability
Maksymilian Kliczkowski, JarosÅaw PawÅowski, Masudul Haque
To what extent do individual eigenstates encode information about their parent Hamiltonian, and how does this encoding vary across the spectrum? We introduce \emph{learnability} as…
Power-law banded random matrix ensemble as a model for quantum many-body Hamiltonians
Wouter Buijsman, Masudul Haque, Ivan M. Khaymovich
We explore interpretations of the power-law banded random matrix (PLBRM) ensemble as Hamiltonians of one-dimensional quantum many-body systems. We introduce and compare a number of…
Dissipation- versus Chaos-Induced Relaxation in Non-Markovian Quantum Many-Body Systems
Gabriel Almeida, Pedro Ribeiro, Masudul Haque +1
In interacting quantum many-body systems, relaxation toward equilibrium reflects a competition between internal chaotic dynamics and environmental dissipation. While conventional M…
Universality, Robustness, and Limits of the Eigenstate Thermalization Hypothesis in Open Quantum Systems
Gabriel Almeida, Pedro Ribeiro, Masudul Haque +1
The eigenstate thermalization hypothesis (ETH) underpins much of our modern understanding of the thermalization of closed quantum many-body systems. Here, we investigate the statis…
Localization and Delocalization of Quantum Trajectories in the Liouvillian Spectrum
Josef Richter, Masudul Haque, Lucas Sá
We develop an approach for understanding the dynamics of open quantum systems by analyzing individual quantum trajectories in the eigenbasis of the Liouvillian superoperator. From…
