Reversible and Irreversible Spacetime Thermodynamics for General Brans-Dicke Theories
Reversible Irreversible Spacetime Thermodynamics General Brans-Dicke Theories
2010/12/20
We derive the equations of motion for Palatini F(R) gravity by applying an entropy balance law
TdS = Q + N to the local Rindler wedge that can be constructed at each point of spacetime.
Unlike pre...
Thermodynamic Potential for Superfluid 3He in Aerogel
Superfluid 3He Aerogel Gapless Superfluid Thermodynamics
2010/11/19
We present a free energy functional for superfluid 3He in the presence of homogeneously distributed impurity disorder which extends the Ginzburg-Landau free energy functional to all temperatures. We u...

Thermodynamics of third order Lovelock anti-de Sitter black holes revisited
2010/12/20
We compute the mass and the temperature of third order Lovelock black holes with negative Gauss-Bonnet coefficient 2 < 0 in anti-de Sitter space and perform the stability analysis of topological blac...
Yang-Yang method for the thermodynamics of one-dimensional multi-component interacting fermions
Yang-Yang method for the thermodynamics one-dimensional multi-component interacting fermions
2010/11/17
Using Yang and Yang’s particle-hole description, we present a thorough derivation of the ther-
modynamic Bethe ansatz equations for a general SU() fermionic system in one-dimension for
both the rep...
Nonequilibrium Phase Diagram of a Driven-Dissipative Many-Body System
Nonequilibrium Phase Diagram Driven-Dissipative Many-Body System
2010/11/22
We study the nonequilibrium dynamics of a many-body bosonic system on a lattice, subject to
driving and dissipation. The time-evolution is described by a master equation, which we treat within a gene...
Thermal Enhancement of Interference Effects in Quantum Point Contacts
Thermal Enhancement Interference Effects Quantum Point Contacts
2010/11/24
We study an electron interferometer formed with a quantum point contact and a scanning probe
tip in a two-dimensional electron gas. The images giving the conductance as a function of the tip position...
Thermodynamics of the HMF model with a magnetic field
ermodynamics of the HMF model magnetic field
2010/11/19
We study the thermodynamics of the Hamiltonian Mean Field (HMF) model with an external
potential playing the role of a “magnetic field”. If we consider only fully stable states, this system does not ...
Thermally induced coherence in a Mott insulator of bosonic atoms
Thermally induced coherence Mott insulator of bosonic atoms
2010/11/24
Conventional wisdom is that increasing temperature causes quantum coherence to decrease. Using finite temperature perturbation theory and exact calculations for the strongly correlated bosonic Mott in...
Dynamics and Thermodynamics of (2+1)-Dimensional Evolving Lorentzian Wormhole
Wormhole Thermodynamics Entropy Horizons
2010/12/20
In this paper we study the relationship between the Einstein field
equations for the (2+1)-dimensional evolving wormhole and the first law of thermodynamics.
It has been shown that the Einstein fiel...
Nonequilibrium Response from the dissipative Liouville Equation
Nonequilibrium Response dissipative Liouville Equation
2010/11/22
The problem of response of nonequilibrium systems is currently under intense investigation. We propose a general method of solution of the Liouville Equation for thermostatted particle systems subject...
Thermodynamical insight on the role of additives in shifting the equilibrium between white and grey tin
white tin grey tin Debye temperature equilibrium transition
2010/11/19
In this study methods of statistical thermodynamics were applied to white tin –grey tin equilibrium to find if there is any correlation between Debye temperature of an additive and its effect on the e...
We use molecular dynamics with a first-principles based shell model potential to study pyroelec-tricity in lithium niobate. We find that the primary pyroelectric effect is dominant, and pyroelec-trici...

Thermodynamics of Third Order Phase Transition Euler-Lagrange Equations
2010/11/22
The thermodynamics expected of systems undergoing third order phase transition has been investigated by identifying the orders through the analytic continuation of the functional of the free energy, u...
Modulation of the thermodynamic, kinetic and magnetic properties of the hydrogen monomer on graphene by charge doping
Modulation of the thermodynamic kinetic magnetic properties graphene by charge doping
2010/11/23
The thermodynamic, kinetic and magnetic properties of the hydrogen monomer on doped graphene layers were studied by ab initio simulations. Electron doping was found to heighten the diffusion potential...
Naively resummed perturbative approximations to the thermodynamic functions of QCD do not converge at phenomenologically relevant temperatures. Here we review recent results of a three-loop hard-therm...
