A common feature of both single- and multiband superconductors is the presence of a crossover between conventional type I and type II superconductivity through an intertype (IT) domain in the phase diagram of the magnetic response. In diffusive single-band superconductors, this domain is known to be very narrow due to scattering by nonmagnetic impurities. Recently, ...

В последние годы некоторые из наиболее важных тем физики опираются на сверхбыстрые однофотонные детекторы: квантовая запутанность и проблема затухания волновой функции во времени; обнаружение фотонов в диапазоне частот темной энергии и т. д. Этот класс электронных устройств может принести несколько прорывов в будущие научные исследования. Идея состоит в том, чтобы исследовать импульсы напряжения в небольших ...

This work introduces an algorithm designed to solve the Bogoliubov–de Gennes equations of superconductivity theory. What sets this algorithm apart is its remarkable ability to precisely and consistently consider the impact of an external magnetic field, all within the microscopic approach. The computation scheme’s convergence is guaranteed by addressing the Biot–Savart equation for the field ...

Nonmagnetic impurity scattering is known to shift up the Ginzburg−Landau parameter k of a superconductor. In this case, when the system is initially in type I, it can change its magnetic response, crossing the intertype domain with k = 1 between the two standard superconductivity types and arriving at type II. In the present work we ...

In this work, we investigate the intertype (IT) domain in strongly disordered ferromagnetic superconductors with a Curie temperature lower than the superconducting critical temperature. In such unique materials, the coexistence of superconductivity and ferromagnetism allows for the exploration of both unconventional superconductivity and the interplay between magnetism and superconductivity. The study utilizes an extended Ginzburg-Landau ...

In many pnictides the superconductivity coexists with ferromagnetism in an accessible range of temperatures and compositions. Recent experiments revealed that when the temperature of magnetic ordering Tm is below the superconducting transition temperature Tc, highly non-trivial physical phenomena occur. In this work we demonstrate the existence of a temperature window, situated between Tm and Tc, where these intrinsically type-II superconductors are ...

By investigating spatial configurations of the intermediate mixed state in an intertype superconductor, it is shown that vortex clustering can be characterized by the sample averaged distribution of the penetrating magnetic field. The clustering is manifested in the two peak structure of the distribution. The second peak indicates a spot a material occupies in the ...

Cluster formation is a focus of interdisciplinary research in both chemistry and physics. Here we discuss the exotic example of this phenomenon in the vortex matter of a thin superconductor. In superconducting films, the clustering takes place because of particular properties of the vortex interactions in the crossover or intertype regime between superconductivity types I ...
