Dynamic susceptibility and dynamic correlations in spin ice

, 2013
Here we calculate the dynamic susceptibility and dynamic correlation function in spin ice using the model of emergent magnetic monopoles. Calculations are based on a method originally suggested for the description of dynamic processes in water ice (non ...

Solutions to the Multi-Component 1/R Hubbard Model

, 1993
In this work we introduce one dimensional multi-component Hubbard model of 1/r hopping and U on-site energy. The wavefunctions, the spectrum and the thermodynamics are studied for this model in the strong interaction limit $U=\infty$.

The holographic interpretation of J T ¯ $$ J\overline{T} $$ -deformed CFTs

Journal of High Energy Physics, 2019
Recently, a non-local yet possibly UV-complete quantum field theory has been constructed by deforming a two-dimensional CFT by the composite operator J T ¯ $$ J\overline{T} $$ , where J is a chiral U(1) current and T ¯ $$ \overline{T} $$ is a component ...

Yang-Yang method for the thermodynamics of one-dimensional multi-component interacting fermions

, 2011
Using Yang and Yang's particle-hole description, we present a thorough derivation of the thermodynamic Bethe ansatz equations for a general $SU(\kappa)$ fermionic system in one-dimension for both the repulsive and attractive regimes under the presence of

Cellular automaton simulation of peritectic solidification of a C-Mn steel [PDF]

China Foundry, 2012
A cellular automaton model has been developed to simulate the microstructure evolution of a C-Mn steel during the peritectic solidification. In the model, the thermodynamics and solute diffusion of multi-component systems were taken into account by using

On large deviation properties of Erdos-Renyi random graphs

, 2004
We show that large deviation properties of Erd\"os-R\'enyi random graphs can be derived from the free energy of the $q$-state Potts model of statistical mechanics.

THERMODYNAMIC QUANTITIES FOR MELTING OF TWO COMPONENT COPOLYMERS

Sen'i Gakkaishi, 1973
On the basis of the theoretical expressions on the melting of two component copolymers reported in our preceding papers, the related thermodynamic quantities were investigated for two kinds of copolyamides. In particular, the heat and the entropy of transition in the amorphous regions for these copolymers were compared quantitatively with those for the

Irreversible thermodynamics of creep in crystalline solids

, 2013
We develop an irreversible thermodynamics framework for the description of creep deformation in crystalline solids by mechanisms that involve vacancy diffusion and lattice site generation and annihilation. The material undergoing the creep deformation is

Surface Charge Effects for the Hydrogen Evolution Reaction on Pt(111) Using a Modified Grand-Canonical Potential Kinetics Method

Molecules
Surface charges of catalysts have important influences on the thermodynamics and kinetics of electrochemical reactions. Herein, we develop a modified version of the grand-canonical potential kinetics (GCP-K) method based on density functional theory (DFT)

Thermodynamic Stability of Wormholes [PDF]

arXiv, 2016
In the context of GR, we study the thermodynamic stability of evolving Lorentzian wormholes at the apparent horizon. The average pressure of the anisotrropic components is considered as the pressure of the wormhole. According to the requirements of stable equilibrium in conventional thermodynamics, we calculate the heat capacity at constant pressure ...
