Thermodynamics of continuous media with intrinsic rotation and magnetoelectric coupling

The thermodynamics of an electrically charged, multicomponent continuous medium with intrinsic rotation is analysed in the presence of electromagnetic fields with a weak linear magnetoelectric coupling in the non-relativistic limit. Taking into account the ...

Flexoelectric effect in finite samples

Alexander Tagantsev

Static flexoelectric effect in a finite sample of a solid is addressed in terms of phenomenological theory for the case of a thin plate subjected to bending. It has been shown that despite an explicit asymmetry inherent to the bulk constitutive electromech ...

Thermodynamics of continuous media with electromagnetic fields

Jean-Philippe Ansermet, Sylvain Bréchet, François Reuse

The thermodynamics of an electrically charged, multicomponent continuous medium with electromagnetic fields is analysed in the non-relativistic limit. Applying locally the first and second law of thermodynamics and Maxwell’s equations for a linear theory o ...

Raman study of the Verwey transition in magnetite at high-pressure and low-temperature: Effect of Al doping

Helmuth Berger

We employed Raman spectroscopy to investigate how the hydrostatic pressure affects the temperature of the Verwey transition in pure (Fe3O4) and Al-doped (Fe2.8Al0.2O4) magnetite. In both samples, pressure suppresses the transition. The Al-doped sample disp ...

Entropy in the Coil-to-Globule Transition of Macromolecules

Carlo Maffi

The coil to globule transition is a fundamental phenomenon in the physics of macro-molecules by reason of the multiplicity of arrangements of their conformation. Such conformational freedom is the main source of entropy in the molecule and is the main oppo ...

Search for Time-Dependent CPT Violation in Hadronic and Semileptonic B Decays

Olivier Schneider, Yiming Li, Aurelio Bay, Chao Wang, Tagir Aushev, Jun Yong Kim, Remi Léandre Albert Louvot, Ji Hyun Kim, Xiao Wang, Jing Li

We report a new sensitive search for C P T violation, which includes improved measurements of the C P T-violating parameter z and the total decay-width difference normalized to the averaged width delta(d) delta(d) of the two B-d mass eigenstates . The resu ...

Multi-domain Fourier-continuation/WENO hybrid solver for conservation laws

Jan Sickmann Hesthaven

We introduce a multi-domain Fourier-continuation/WENO hybrid method (FC-WENO) that enables high-order and non-oscillatory solution of systems of nonlinear conservation laws, and which enjoys essentially dispersionless, spectral character away from disconti ...

Experimental charge density of LiBD4 from maximum entropy method

Philippe Mauron

We report on maximum entropy method study of the experimental atomic and ionic charges of LiBD4 in its low-temperature orthorhombic phase. Synchrotron radiation x-ray powder diffraction data, neutron powder diffraction data, and density functional calculat ...

Direct comparison of phase-sensitive vibrational sum frequency generation with maximum entropy method: Case study of water

Sylvie Roke

We present a direct comparison of phase sensitive sum-frequency generation experiments with phase reconstruction obtained by the maximum entropy method. We show that both methods lead to the same complex spectrum. Furthermore, we discuss the strengths and ...

Lagrange Equations Coupled to a Thermal Equation: Mechanics as Consequence of Thermodynamics

Sylvain Bréchet, Christian Gruber

Following the analytic approach to thermodynamics developed by Stuckelberg, we study the evolution equations of a closed thermodynamic system consisting of point particles in a fluid. We obtain a system of coupled differential equations describing the mech ...
