Anomalous transport in long-ranged open quantum systems

A Dhawan, K Ganguly, M Kulkarni, BK Agarwalla - Physical Review B, 2024 - APS
We consider a one-dimensional fermionic lattice system with long-ranged power-law
decaying hopping with exponent α. The system is further subjected to dephasing noise in …

Generalized Hydrodynamic Description of the Page Curve–like Dynamics of a Freely Expanding Fermionic Gas

M Saha, M Kulkarni, A Dhar - Physical Review Letters, 2024 - APS
We consider an analytically tractable model that exhibits the main features of the Page curve
characterizing the evolution of entanglement entropy during evaporation of a black hole. Our …

Non-Markovian Gravitational Decoherence and the Black Hole Information Paradox

Y Li - International Journal of Theoretical Physics, 2024 - Springer
An isolated system always evolves according to unitary evolution and maintain coherence.
However the system inevitably interacts with the environment, information about the relative …

Quantum Thermodynamics Close to the Absolute Zero

J Glatthard - 2024 - ore.exeter.ac.uk
Quantum effects often become most pronounced close to the absolute zero. The prospect of
quantum technologies therefore calls for theoretical understanding and experimental control …

Generalized Loschmidt echo and information scrambling in open systems

YN Zhou, C Liu - arXiv preprint arXiv:2412.01851, 2024 - arxiv.org
Quantum information scrambling, typically explored in closed quantum systems, describes
the spread of initially localized information throughout a system and can be quantified by …
