We present the first model aimed at understanding how the Meissner effect in a young neutron star affects its macroscopic magnetic field. In this model, field expulsion occurs on a dynamical timescale, and is realised through two processes that occur

We explore the consequences of a new mechanism for the rapid onset of the Meissner effect in a young neutron star, via an interplay of field-line advection by fluid motion and magnetic reconnection. This mechanism provides the first justification for

We consider extreme type-II superconductors modeled by the Ginzburg--Landau energy with a pinning term $a_\varepsilon(x)$, which we assume to be a bounded measurable function such that $b\leq a_\varepsilon(x)\leq 1$ for some constant $b>0$. A crucial

Interplay of Tilt and Axion Fields in Topological Superconductors: Anisotropy in the Meissner Effect
Autor:
Hasani, Mojtaba, Faraei, Zahra
The surface states of topological superconductors significantly influence electromagnetic fields within these materials. The interaction between gapless boundary states and electromagnetic fields induces a Berry phase, coupling electric and magnetic

Recent reports on the signatures of high-temperature superconductivity with a critical temperature Tc close to 80 K have triggered great research interest and extensive follow-up studies. Although zero-resistance state has been successfully achieved

We study theoretically Meissner effect in non-Hermitian systems of BCS type via superfluid stiffness. We show that depending on the values of the mean fields, chemical potential, and temperature, we obtain paramagnetic or diamagnetic Meissner effect.

In Entropy 24, 83 (2022) [1], titled "The Law of Entropy Increase and the Meissner Effect", A. Nikulov claims that the Meissner effect exhibited by type I superconductors violates the second law of thermodynamics. Contrary to this claim, I show that

High-Q superconducting resonators have been proposed and developed as detectors of light-by-light scattering mediated by the hypothesized axion or virtual electron-positron pairs in quantum electrodynamics - the Euler-Heisenberg (EH) interaction. Pho
