We study leading order singularities of the wave trace Aharonov–Bohm Hamiltonian on $$\mathbf {R}^2$$ with multiple solenoids under a generic assumption that no three are collinear. Then we apply our formula to get lower bound scattering resonances in logarithmic neighborhood near real axis.

We obtain exact solutions of the (1+1) dimensional Klein Gordon equation with linear vector and scalar potentials in the presence of a minimal length. Algebraic approach to the problem has also been studied.

Two models are given by crossing the Friedmann metrics with Schwarzschild and Kerr metrics. In these evolving universes with a gravitational source, the force four-vector and the corresponding potentials are evaluated. ∗e-mail: [email protected] 1

The presence of a nonvanishing totally antisymmetric (super)torsion, equivalent to an axial vector, and higher forms in the “new minimal” “old off-shell formulations N = 1 $\mathcal {N}=1$ , D 4 $D=4$ supergravity is elaborated. geometric superspace approach study both Lagrangian closure Bianchi identities this framework, showing how aforementioned vector torsion contributes new old minimal set...

A generalization of scalar electrodynamics called fluid electrodynamics is presented. In this theory a fluid replaces the Higgs scalar field. Fluid electrodynamics might have application to the theory of low temperature Helium superfluids, but here it is argued that it provides an alternative method of approaching symmetry breaking in particle physics. The method of constructing fluid electrody...

Large-scale recording from a population of neurons is a promising strategy for approaching the study of complex brain functions. Taking advantage of the fact that action potentials reliably evoke transient calcium fluctuations in the cell body, functional multineuron calcium imaging (fMCI) monitors the suprathreshold activity of hundreds of neurons. However, a limitation of fMCI is its semi-man...
