Entropy correction and phase transition of n-dimensional charged dilaton dS black holes

European Physical Journal C: Particles and Fields
The manifest disparity in Hawking radiation temperatures between black hole and cosmological horizons in de Sitter (dS) spacetime reveals a non-equilibrium thermal configuration, inherently violating thermodynamic stability criteria. This asymmetry poses

Why so many "Schools" of Thermodynamics?

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
A classification representing some main branches of phenomenological non-equilibrium thermodynamics is discussed. Differences and similarities of these selected branches are explained.

Optical Control of the Thermal Conductivity in BaTiO3

Advanced Functional Materials, EarlyView.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter

Thermodynamic theory of equilibrium fluctuations

Annals of Physics, 2015
The postulational basis of classical thermodynamics has been expanded to incorporate equilibrium fluctuations. The main additional elements of the proposed thermodynamic theory are the concept of quasi-equilibrium states, a definition of non-equilibrium entropy, a fundamental equation of state in the entropy representation, and a fluctuation postulate ...

Terahertz‐Driven Ultrafast Dynamics of Rare‐Earth Nickelates by Controlling Only the Charge Degree of Freedom

Advanced Functional Materials, EarlyView.
The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

Strain Partitioning at the Oxide Interface for the Isothermal Phase Transition in Freestanding Tri‐Layers

Advanced Functional Materials, EarlyView.
The metal–insulator transition temperature (TMI) is continuously tuned by the systematic change of relative thickness in VO2 and TiO2 films (tVO2/tTiO2${t_{{\mathrm{V}}{{\mathrm{O}}_2}}}/{t_{{\mathrm{Ti}}{{\mathrm{O}}_2}}}$) in freestanding TiO2/VO2/TiO2 tri‐layers.

Exploitation of a special-relativistic entropy identity for one component of a multi-component system

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
Non-equilibrium and equilibrium thermodynamics of an interacting component of a special-relativistic multi-component system is discussed by using an entropy identity. The special case of the corresponding free component is considered.

Relativistic Statistical Mechanics vs. Relativistic Thermodynamics

Entropy, 2011
Based on a covariant theory of equilibrium Thermodynamics, a Statistical Relativistic Mechanics is developed for the non-interacting case. Relativistic Thermodynamics and Jüttner Relativistic Distribution Function in a moving frame are obtained by using ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.
