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 ...

Self‐Poled Halide Perovskite Ruddlesden‐Popper Ferroelectric‐Photovoltaic Semiconductor Thin Films and Their Energy Harvesting Properties

Advanced Functional Materials, EarlyView.
Low‐dimensional halide perovskite thin films, (BA)2(MA)n‐1PbnBr3n+1 (n = 1, 2), exhibit both semiconducting and ferroelectric properties, enabling mechanical and light energy harvesting. Using Cr/Cr₂O₃ or PCBM as barrier layers ensures reproducible ferroelectricity.

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

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 ...

Black holes and thermogeometric optimization

European Physical Journal C: Particles and Fields
We suggest a finite-time geometric optimization framework to analyze thermal fluctuations and optimal processes in black holes. Our approach implement geodesics in thermodynamic space to define optimal pathways between equilibrium and non-equilibrium ...

Dynamic Networks via Polymerizable Deep Eutectic Monomers for Uniform Li+ Transport at Interfaces in Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
The PDEM‐based SIGPE provides a dynamic nanophase from Li+‐bridged molecular self‐association, enhancing electrochemical stability and facilitating uniform Li+ ion flux at the interface. This unique solvation structure results in a hetero species‐driven inorganic‐rich SEI and long‐term cycle stability, suggesting that a PFAS‐free Li+‐containing monomer

Unified representation of homogeneous and quasi-homogenous systems in geometrothermodynamics

Physics Letters B, 2023
We analyze homogeneous and quasi-homogeneous thermodynamic systems within the formalism of geometrothermodynamics (GTD). A generalized Euler identity is used to obtain the explicit form of the three Legendre invariant metrics that are known in GTD for ...
