A Lagrangian description of the qubit based on Schwinger’s picture of Quantum Mechanics that allows for a Feynman-like computation of its probability amplitudes is presented. The Lagrangian is a function on the groupoid that describes the qubit and at the same time determines a self-adjoint element on its associated algebra. Feynman’s paths are replaced by histories on the groupoid which form a groupoid

An exact solution for the magnetic diffusion problem with a step-function resistivity model Eur. Phys. J. Plus (IF 3.4) Pub Date : 2024-04-02 Bo Xiao, Ganghua Wang, Li Zhao, Chunsheng Feng, Shi Shu
In the magnetic diffusion problem, a magnetic diffusion equation is coupled by an Ohmic heating energy equation. The Ohmic heating can make the magnetic diffusion coefficient (i.e. the resistivity) vary violently, and make the diffusion a highly nonlinear process. For this reason, the problem is normally very hard to be solved analytically. In this article, under the condition of a step-function resistivity

The study of reheating in inflationary models is crucial to understand the early universe and obtain information about the dynamics and parameters of inflation. The reheating temperature \(T_{re}\) and the duration of the reheating phase, quantified by the number of e-folds \(N_{re}\), have significant implications for particle production, thermalisation, and the primordial power spectrum. The duration

Supervariable approach to particle on a torus knot: a model for Hodge theory Eur. Phys. J. Plus (IF 3.4) Pub Date : 2024-03-31 Anjali S, Saurabh Gupta
We analyze a particle constrained to move on a (p, q)-torus knot within the framework of supervariable approach and deduce the BRST as well as anti-BRST symmetries. We also capture the nilpotency and absolute anti-commutativity of (anti-)BRST symmetries in this framework. Further, we show the existence of some novel symmetries in the system such as (anti-)co-BRST, bosonic, and ghost scale symmetries

Violation of the third law of thermodynamics by black holes, Riemann zeta function and Bose gas in negative dimensions Eur. Phys. J. Plus (IF 3.4) Pub Date : 2024-03-30 Irina Aref’eva, Igor Volovich
Black holes violate the third law of thermodynamics in its standard formulation. Schwarzschild black hole entropy is inverse proportional to the square of the temperature \(S=1/(16 \pi T^2)\) and tends to infinity rather than zero when the temperature goes to zero. We search for quantum statistical models with such exotic thermodynamic behaviour. It is shown that the Schwarzschild black hole in \(D=4\)

On the symmetries of elementary fermions Eur. Phys. J. Plus (IF 3.4) Pub Date : 2024-03-21 Eckart Marsch, Yasuhito Narita
This paper deals with the symmetries of elementary fermions and their derivation from fundamental physical principles such as the Lorentz invariance and from the spinor-helicity formalism employed to three-vectors. The generators of the Lorentz group are discussed, and the physics of the associated chiral spins is used to establish the chiral symmetry SU(2). The helicity of spin is defined which, when
