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, Jarosław Pawłowski, 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…
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…
Supercharging exceptional points: Full-spectrum pairwise coalescence in non-Hermitian systems
Yusuf H. Erdogan, Masudul Haque
We consider non-Hermitian tight-binding one-dimensional Hamiltonians and show that imposing a certain symmetry causes all eigenvalues to pair up and the corresponding eigenstates t…
Quantum Origin of Limit Cycles, Fixed Points, and Critical Slowing Down
Shovan Dutta, Shu Zhang, Masudul Haque
Among the most iconic features of classical dissipative dynamics are persistent limit-cycle oscillations and critical slowing down at the onset of such oscillations, where the syst…
Structure of the Hamiltonian of mean force
Phillip C. Burke, Goran Nakerst, Masudul Haque
The Hamiltonian of mean force is an effective Hamiltonian that allows a quantum system, non-weakly coupled to an environment, to be written in an effective Gibbs state. We present…
