Mathematics
Probability
The article is devoted to the expansions of iterated Stratonovich stochastic
integrals of multiplicities 1 to 6 on the basis of the method of generalized
multiple Fourier series that converge in the sense of norm in Hilbert space

We propose a framework based on the concept of the semigroup to understand
the fermion sign problem. By using properties of contraction semigroups, we
obtain sufficient conditions for quantum lattice fermion models to be
sign-problem-free. ...
Revisiting the charging-capacitor problem

Classical Physics
The charging capacitor is used as a standard paradigm for illustrating the
concept of the Maxwell "displacement current". A certain aspect of the problem,
however, is often overlooked. It concerns the conditions for satisfaction of
the Fara...

We estimate the chemical freeze-out of light nuclear clusters for NICA
energies of above 2 A GeV. On the one hand we use results from the low energy
domain of about 35 A MeV, where medium effects have been shown to be important
to explain e...

We study different behavioral metrics, such as those arising from both
branching and linear-time semantics, in a coalgebraic setting. Given a
coalgebra α:X→HX for a functor H:Set→Set, we define...

Conservation of angular momentum depends on the existence of rotational
symmetry. However, even in systems where this symmetry is broken, flipping
between angular momentum eigenstates often requires an activation energy. Here
we discuss an ...

The purpose of this paper is to study minimal modular extensions of braided
fusion categories, with emphasis on minimal modular extensions of
super-Tannakian fusion categories. We define actions of finite super-groups on
fermionic fusion ca...

The axiomatic theory of quantum first-kind measurements is developed in a
rigorous form based on five Postulates. The measurement theory for observable
with continuous spectrum is given in a rigged Hilbert space. This approach also
describe...

Let G be a real classical group (including the real metaplectic group). We

Choreographic programming promises a simple approach to the coding of
concurrent and distributed systems: write the collective communication
behaviour of a system of processes as a choreography, and then the programs for
these processes are...
