New Solutions To The Bianchi IX Wheeler DeWitt Equation And Leading Order Solutions For $\Lambda$ $\ne$ 0 And A Primordial Magnetic Field

New closed form solutions to the Lorentzian signature symmetry reduced Bianchi IX Wheeler DeWitt equation are obtained using a Euclidean-signature semi classical method for Hartle Hawking ordering parameters $ \pm 2\sqrt{33} $ for the wormhole Hamilton-Jacobi solution. Expand abstract.

The influence of crosslinkers and magnetic particle distribution along the filament backbone on the magnetic properties of supracolloidal linear polymer-like chains

In the case where all or part of these colloidal particles are magnetic, one can control the behaviour of these supracolloidal polymers, known as magnetic filaments (MFs), by applied magnetic fields. Expand abstract.

Scaling behavior of Charge order melting in Magnetic field-Pressure-Temperature space of 2.5% Al doped Pr$_{0.5}$Ca$_{0.5}$MnO$_3$

Dc magnetic measurements across the charge ordering (CO) transition temperature (T$_{CO}$) in polycrystalline Pr$_{0.5}$Ca$_{0.5}$Mn$_{0.975}$Al$_{0.025}$O$_3$ have been performed under simultaneous influence of external hydrostatic pressure (P) and magnetic field (H). Expand abstract.

Polarized Line Formation in Arbitrary Strength Magnetic Fields: the case of a two-level atom with hyperfine structure splitting

Quantum interference effects together with partial frequency redistribution (PFR) in line scattering produce subtle signatures in the so called Second Solar Spectrum (the linearly polarized spectrum of the Sun). Expand abstract.

Magnetic Field Effect in the Fine-Structure Constant and Electron Dynamical Mass

We find that in both cases of massive and massless QED, the electron dynamical mass always decreases with the magnetic field, what can be interpreted as an inverse magnetic catalysis effect. Expand abstract.

Weak decays of magnetized charged pions in the symmetric gauge

We consider the decay $\pi^- \to l \, \bar{\nu}_l$ ($l=e^-,\,\mu^-$) in the presence of an arbitrary large uniform magnetic field, using the symmetric gauge. Expand abstract.
