Molecules, 2022 Overhauser dynamic nuclear polarization (ODNP) can be used as a tool for NMR signal enhancement and happens on very short time scales. Therefore, ODNP is well suited for the measurement of fast-flowing samples, even in compact magnets, which is ...

Generalized Second Law of Thermodynamics for Non-canonical Scalar Field Model with Corrected-Entropy [PDF]
, 2015 In this work, we have considered a non-canonical scalar field dark energy model in the framework of flat FRW background. It has also been assumed that the dark matter sector interacts with the non-canonical dark energy sector through some interaction ...

Communications Engineering, 2023 During phase change, phase change materials absorb or release latent heat at a nearly constant temperature. Latent heat thus can be stored and integrated with evaporation/condensation systems such as steam generators within a relatively narrow range of ...

Thermodynamic holography [PDF]
Scientific Reports, 2015 AbstractThe holographic principle states that the information about a volume of a system is encoded on the boundary surface of the volume. Holography appears in many branches of physics, such as optics, electromagnetism, many-body physics, quantum gravity and string theory. Here we show that holography is also an underlying principle in thermodynamics,

Quantum Thermodynamics: A Nonequilibrium Green's Functions Approach [PDF]
, 2015 We establish the foundations of a nonequilibrium theory of quantum thermodynamics for noninteracting open quantum systems strongly coupled to their reservoirs within the framework of the nonequilibrium Green functions (NEGF). The energy of the system and

Gravitational thermodynamics [PDF]
Complexity, 1997 The gravitational N-body problem, for $N>2$, is the oldest unsolved problem in mathematical physics. Some of the most ideal examples that can be found in nature are globular star clusters, with $N \sim 10^6$. In this overview, I discuss six types of fundamental sources of unpredictability, each of which poses a different challenge to attempts to ...

Macroscopic thermodynamics of equilibrium characterized by power-law canonical distributions
, 2000 Macroscopic thermodynamics of equilibrium is constructed for systems obeying power-law canonical distributions. With this, the connection between macroscopic thermodynamics and microscopic statistical thermodynamics is generalized.

The postulates of gravitational thermodynamics [PDF]
, 1996 The general principles and logical structure of a thermodynamic formalism that incorporates strongly self-gravitating systems are presented. This framework generalizes and simplifies the formulation of thermodynamics developed by Callen.
