Cosmology Due to Thermodynamics of Apparent Horizon
Annalen der Physik, EarlyView.Effective cosmological constant as a function of the Hubble rate H for different entropy parameters b. Figure shows the asymptotic of the effective cosmological constant. At H = 0 the effective cosmological constant vanishes. Abstract This study proposes new entropy of the apparent horizon Sh=(1/β)arctan(βSBH)$S_h=(1/\beta)\arctan (\beta S_{BH ...

Supercurrents and Tunneling in Massive Many‐Vortex Necklaces and Star‐Lattices
Annalen der Physik, EarlyView.It is numerically shown how massive many‐vortex systems, in a mixture of Bose–Einstein condensates, can host the bosonic tunneling of the infilling component in an almost‐periodic way when the vortices are organized in necklaces or star‐lattices. The purpose is to explore the conditions for the onset of Josephson supercurrents in rotating many‐vortex ...

Boundary effects in super-Yang–Mills theory
European Physical Journal C: Particles and Fields, 2017 In this paper, we shall analyze a three dimensional supersymmetry theory with $$\mathcal {N} = 2$$ N = 2 supersymmetry. We will analyze the quantization of this theory, in the presence of a boundary.

The Stochastic‐Dissipative Störmer Problem‐Trajectories and Radiation Patterns
Annalen der Physik, EarlyView.We consider charged particle motion and radiation in a dipole magnetic field, in the presence of friction and of stochastic forces. The numerical solutions of the Langevin equation reveal how these forces modify the complex dynamics of particles, and they offer some new insights into the nonlinear processes relevant to planetary radiation belts ...

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity
Annalen der Physik, EarlyView.This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...

Inverting Palladium–Phosphorus Lewis Pair Formation: Phosphonium Acting as Z‐Type Ligand
Angewandte Chemie International Edition, EarlyView.A series of cationic phosphonium‐palladium(0) complexes were synthesized using an ambiphilic phosphorus‐based ligand. A strong Z‐type interaction was identified by DFT calculations (NBO, ETS‐NOCV, and QTAIM analyses), surpassing the strength of classical L‐type P─Pd bonds.

Lagrangian Pairs and Lagrangian Orthogonal Matroids
, 2002 Represented Coxeter matroids of types $C_n$ and $D_n$, that is, symplectic and orthogonal matroids arising from totally isotropic subspaces of symplectic or (even-dimensional) orthogonal spaces, may also be represented in buildings of type $C_n$ and $D_n$
