The Dynamics of Thermodynamics
J. Kumicak, X. de Hemptinne
Thermodynamic relations are derived from first principles of mechanics for non-equilibrium processes. Since the key role herein is played by the law of increase of entropy, the lat…
N=2 Supergravity and Special Geometry
Antoine Van Proeyen
The essential elements in the construction of the couplings of vector multiplets to supergravity using the conformal approach are repeated. This approach leads automatically to the…
Target Space Supersymmetric Sigma Model Calculations
Jan de Boer, Kostas Skenderis
We briefly review the covariant formulation of the Green-Schwarz superstring by Berkovits, and describe how a detailed tree-level and one-loop analysis of this model leads, for the…
A Transfer Matrix study of the staggered BCSOS model
Enrico Carlon, Giorgio Mazzeo, Henk van Beijeren
The phase diagram of the staggered six vertex, or body centered solid on solid model, is investigated by transfer matrix and finite size scaling techniques. The phase diagram conta…
Pairing and Quantum Double of Multiplier Hopf Algebras
Bernhard Drabant, Alfons Van Daele
We define and investigate pairings of multiplier Hopf algebras. It is shown that two dually paired regular multiplier Hopf (-)algebras and yield a quantum double multipl…
Local BRST cohomology in minimal D=4, N=1 supergravity
Friedemann Brandt
The local BRST cohomology is computed in old and new minimal supergravity, including the coupling to Yang-Mills gauge multiplets. This covers the determination of all gauge invaria…
Laboratory Constraints on a 33.9 MeV/c^2 Isosinglet Neutrino: Status and Perspectives
Jan Govaerts, Jules Deutsch, Pierre M. Van Hove
An anomaly in the time behaviour of the signals observed by the KARMEN Collaboration may be interpreted as the possible decay signature of a 33.9 MeV/c mainly sterile neutrino.…
Bicovariant Differential Calculi and Cross Products on Braided Hopf Algebras
Yuri Bespalov, Bernhard Drabant
We consider Hopf bimodules and crossed modules over a Hopf algebra in a braided category. They are the key-stones for braided bicovariant differential calculi and their invaria…
Higher Loop Anomalies and their Consistency Conditions in Nonlocal Regularization
Jordi París, Walter Troost
An algebraic program of computation and characterization of higher loop BRST anomalies is presented. We propose a procedure for disentangling a genuine{\it local} higher loop anoma…
Generalized gradient approximations to density functional theory: comparison with exact results
Claudia Filippi, Xavier Gonze, C. J. Umrigar
In order to assess the accuracy of commonly used approximate exchange-correlation density functionals, we present a comparison of accurate exchange and correlation potentials, exch…
The Canonical Form of the Rabi Hamiltonian
Marek Szopa, Geert Mys, Arnout Ceulemans
The Rabi Hamiltonian, describing the coupling of a two-level system to a single quantized boson mode, is studied in the Bargmann-Fock representation. The corresponding system of di…
Global Symmetries in the Antifield-Formalism
Friedemann Brandt, Marc Henneaux, André Wilch
In this paper, two things are done. (i) First, it is shown that any global symmetry of a gauge-invariant theory can be extended to the ghosts and the antifields so as to leave inva…
The Definitions of Special Geometry
Ben Craps, Frederik Roose, Walter Troost +1
The scalars in vector multiplets of N=2 supersymmetric theories in 4 dimensions exhibit `special Kaehler geometry', related to duality symmetries, due to their coupling to the vect…
Projection Operator Approach to Constrained Systems
Jan Govaerts
Recently, within the context of the phase space coherent state path integral quantisation of constrained systems, John Klauder introduced a reproducing kernel for gauge invariant p…
On the determination of anomalies in supersymmetric theories
Friedemann Brandt, Jordi París
We develop an efficient technique to compute anomalies in supersymmetric theories by combining the so-called nonlocal regularization method and superspace techniques. To illustrate…
Long Wavelength Instability for Uniform Shear Flow
Mirim Lee, James W. Dufty, José M. Montanero +2
Uniform Shear Flow is a prototype nonequilibrium state admitting detailed study at both the macroscopic and microscopic levels via theory and computer simulation. It is shown that…
Local BRST cohomology and covariance
Friedemann Brandt
The paper provides a framework for a systematic analysis of the local BRST cohomology in a large class of gauge theories. The approach is based on the cohomology of s+d in the jet…
Giant Low Temperature Heat Capacity of GaAs Quantum Wells near Landau Level Filling =1
V. Bayot, E. Grivei, S. Melinte +2
We report low temperature () heat capacity () data on a multiple-quantum-well GaAs/AlGaAs sample in the quantum Hall regime. Relative to its low field magnitude, exhibits…
The BPHZ renormalised BV master equation and Two-loop Anomalies in Chiral Gravities
Frank De Jonghe, Jordi Paris, Walter Troost
Anomalies and BRST invariance are governed, in the context of Lagrangian Batalin-Vilkovisky quantization, by the master equation, whose classical limit is . Using Zimmerm…
Neutrino Decay of Positronium in the Standard Model and Beyond
Jan Govaerts, Marc Van Caillie
Whether in the Standard Model or beyond it, neutrinos contribute to the invisible decay mode of orthopositronium but practically not at all to that of parapositronium. Although thi…
Coulomb interaction and ferroelectric instability of BaTiO3
Ph. Ghosez, X. Gonze, J. -P. Michenaud
Using first-principles calculations, the phonon frequencies at the point and the dielectric tensor are determined and analysed for the cubic and rhombohedral phases of BaTiO$_{…
