Dephasing Dynamics in a Non-Equilibrium Fluctuating Environment
Entropy, 2023 We performed a theoretical study of the dephasing dynamics of a quantum two-state system under the influences of a non-equilibrium fluctuating environment. The effect of the environmental non-equilibrium fluctuations on the quantum system is described by

Advanced Electronic Materials, EarlyView.Resistive memory devices are explored for operation at extremely low temperatures relevant to quantum computing. The study reveals how transistor behavior strongly influences memory performance under cryogenic conditions and introduces an optimized programming strategy.

Some Trends in the Philosophy of Physics
Theoria, 2011 A short review of some recent developments in the philosophy of physics is presented. I focus on themes which illustrate relations and points of common interest between philosophy of physics and three of its `neighboring' elds: Physics, metaphysics and ...

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range
Advanced Electronic Materials, EarlyView.A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Advanced Intelligent Discovery, EarlyView.In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...

Discerning the Nature of Neutrinos: Decoherence and Geometric Phases
Universe, 2020 We present new approaches to distinguish between Dirac and Majorana neutrinos. The first is based on the analysis of the geometric phases associated to neutrinos in matter, the second on the effects of decoherence on neutrino oscillations.

Unintegrated Gluon Distributions as Probability Densities for QCD Dynamical Entropy
Astronomische Nachrichten, EarlyView.ABSTRACT We present a systematic procedure for constructing normalized transverse momentum probability distributions from phenomenological unintegrated gluon distributions (UGDs). These distributions provide the probabilistic foundation of the QCD dynamical entropy formalism and can be employed in the evaluation of other statistical observables.

Quantum Chaos and Quantum Randomness—Paradigms of Entropy Production on the Smallest Scales
Entropy, 2019 Quantum chaos is presented as a paradigm of information processing by dynamical systems at the bottom of the range of phase-space scales. Starting with a brief review of classical chaos as entropy flow from micro- to macro-scales, I argue that quantum ...
