Paraparticles intrinsically exhibit Hardy-space breakdown
Kejun Liu
The paper shows that particles with non‑unitary exchange statistics (paraparticles) inherently violate the Hardy‑space analyticity required for Kramers–Kronig relations in the memo…
Unique temporal scaling dimension for quantum criticality in open systems weakly coupled to environment
Fan Zhong
The paper introduces a distinct temporal renormalization‑group eigenvalue for quantum criticality in open systems weakly coupled to a finite‑temperature environment, showing that t…
Optimal Control of thermally noisy quantum gates in a multilevel system
Aviv Aroch, Shimshon Kallush, Ronnie Kosloff
The paper applies optimal control theory within a thermodynamically consistent Markovian framework to design high‑fidelity quantum gates that mitigate thermal noise, comparing dire…
Variational Multi-Gaussian Phase-Space Dynamics via Automatic Differentiation
Jacopo Tosca, Francesco Carnazza, Luca Giacomelli +1
The paper presents a variational multi-Gaussian approach for simulating the dynamics of interacting open quantum bosonic systems, using a Wigner phase-space representation and auto…
Geometric Quantum Thermodynamic Engine under an Isothermal Operation: An Application of a Thouless Pumping
Ryosuke Yoshii, Hisao Hayakawa
The paper demonstrates that a cyclically driven open quantum system can act as an isothermal engine by extracting work from the geometry of its steady-state manifold, rather than f…
On light cone bounds for Markov quantum open systems
Israel Michael Sigal, Xiaoxu Wu
The paper investigates the space‑time propagation of solutions to von Neumann‑Lindblad equations for Markov quantum open systems and proves that their influence is confined within…
