A Generalized Landauer's Principle for Unitarily Transformed Thermal Reservoirs

Hao Xu

Landauer's principle, a cornerstone of quantum information and thermodynamics, appears to be violated when the thermal reservoir is replaced by a squeezed thermal state (STS), owin…

Effective dark matter component presents a robust signature of negative pressure by the DESI observations

Hao Xu, Xinhe Meng

Comprehensive cosmological analysis of an effective non-standard dark matter(NSDM) model, characterized by an equation of state , which allows for mild d…

Measurement-Induced Perturbations of Hausdorff Dimension in Quantum Paths

You-Wei Ding, Yen Chin Ong, Hao Xu

In a seminal paper, Abbott et al. analyzed the relationship between a particle's trajectory and the resolution of position measurements performed by an observer at fixed time inter…

Hessian spectrum at the global minimum of the spherical pure-like mixed p-spin glasses

Hao Xu, Haoran Yang

We study the large -dimensional limit of the Hessian spectrum at the global minimum of some subclasses of the spherical mixed -spin models. Specifically, we show that its emp…

Momentum-Resolved Probing of Lorentz-Violating Dispersion Relations via Unruh-DeWitt Detector

Hao Xu

Inspired by quantum gravity frameworks predicting Planck-scale deviations from Lorentz invariance, we probe Lorentz symmetry violation via modified dispersion relations $ω_{|\text…

Energy change and Landauer's principle in the interaction between qubit and quantum field theory

Hao Xu

We give a general description of the system evolution under the interaction between qubit and quantum field theory up to the second order perturbation, which is also referred to as…
