Complex Langevin equations and Schwinger–Dyson equations
Abstract Stationary distributions of complex Langevin equations are shown to be the complexified path integral solutions of the Schwinger–Dyson equations of the associated quantum field theory. Specific examples in zero dimensions and on a lattice...

High Efficiency Step-Up HVDC Converter for Photovoltaic Generator
Abstract Nowadays a way to optimize photovoltaic systems consists in implementing distributed structures, implying the use of electronic devices. In this paper we show performances of improved DC-DC converters able to feed an inverter. Resulting...

Balance functions in coalescence model
Abstract It is shown that the quark–antiquark coalescence mechanism for pion production allows to explain the small pseudorapidity width of the balance function observed for central collisions of heavy ions, provided effects of the finite acceptance ...

Non-Fermi liquid behavior induced by resonant diquark-pair scattering in heated quark matter
Abstract We show how the quasiparticle picture of quarks changes near but above the critical temperature T c of the...

Violation of angular momentum selection rules in quantum gravity
Abstract A simple consequence of the angular momentum conservation in quantum field theories is that the interference of s-channel amplitudes exchanging particles with different spin J vanishes after complete angular integration. We show that, while ...

Poincaré invariant gravity with local supersymmetry as a gauge theory for the M-algebra
Abstract Here we consider a gravitational action having local Poincaré invariance which is given by the dimensional continuation of the Euler density in ten dimensions. It is shown that the local supersymmetric extension of this action requires the...

Propagation of cosmic rays in the foam-like Universe
Abstract The model of a classical spacetime foam is considered, which consists of static wormholes embedded in Minkowski spacetime. We examine the propagation of particles in such a medium and demonstrate that a single thin ray undergoes a specific...

Quantum tunneling and black hole spectroscopy
Abstract The entropy-area spectrum of a black hole has been a long-standing and unsolved problem. Based on a recent methodology introduced by two of the authors, for the black hole radiation (Hawking effect) as tunneling effect, we obtain the...

Pseudo-Majoron as dark matter
Abstract We consider the singlet Majoron model with softly broken lepton number. This model contains three right-handed neutrinos and a singlet scalar besides the standard model fields. The real part of the singlet scalar develops a vacuum...

Veneziano–Yankielowicz superpotential terms in N=1 SUSY gauge theories
Abstract The Veneziano–Yankielowicz glueball superpotential for an arbitrary N=1 SUSY pure gauge theory with classical gauge group is derived using an approach following recent work of Dijkgraaf, Vafa and others. These...

Impact of squark generation mixing on the search for gluinos at LHC
Abstract We study gluino decays in the Minimal Supersymmetric Standard Model (MSSM) with squark generation mixing. We show that the effect of this mixing on the gluino decay branching ratios can be very large in a significant part of the MSSM...

Quark matter nucleation in hot hadronic matter
Abstract We study the quark deconfinement phase transition in hot β-stable hadronic matter. Assuming a first order phase transition, we calculate the enthalpy per baryon of the hadron–quark phase transition. We calculate and compare the nucleation...

Vector current conservation and neutrino emission from singlet-paired baryons in neutron stars
Abstract Neutrino emission caused by singlet Cooper pairing of baryons in neutron stars is recalculated by accurately taking into account for conservation of the vector weak currents. The neutrino emissivity via the vector weak currents is found to...

The thawing dark energy dynamics: Can we detect it?
Abstract We consider different classes of scalar field models including quintessence and tachyon scalar fields with a variety of generic potentials belonging to the thawing type. We focus on observational quantities like Hubble parameter, luminosity ...
