摘要

最近，在研究和商业应用中使用超快单光子探测器的兴趣引起了科学界的极大关注。探测过程中的动态事件包括光子导致阶次参数的局部破坏，然后外加电流散热，使材料更加脱离超导状态，进而在测量设备中产生尖峰电压。我们研究了广义时变金兹堡-朗道（GTDGL）理论中的超导参数和热参数在临界温度附近超导体中首次涡流穿透和热耗散事件中的作用。此外，在静态金兹堡-朗道理论的博戈莫尔尼点附近，即 κ ≈ 1/√2 和 T → Tc 时，我们发现了严重不同的涡旋剖面。我们指出，在 GTDGL 理论中，杂质（通常或顺磁性）的存在会影响磁通量的穿透，并增强热量的耗散，从而导致异常的涡旋构型。

Dynamics of Vortex Matter in 2D Gapless Superconducting Materials with Impurities.

The recent interest in using ultrafast single-photon detectors in research and commercial applications has garnered significant attention from the scientific community. The dynamic event in the detection process consists of a photon causing local destruction of the order parameter, and then the applied current dissipates heat, bringing the material even more out of the superconducting state and then spiking a voltage peak in a measurement device. We investigated the role of superconducting and thermal parameters of the Generalized Time-Dependent Ginzburg-Landau (GTDGL) theory within the event of the first vortex penetration and the thermal dissipation in superconductors near the critical temperature. Moreover, in the vicinity of the Bogomolny point of the static Ginzburg-Landau theory, where κ ≈ 1/√2 and T → Tc, it has been found severely different vortex profiles. We point out that within the GTDGL theory, the presence of impurities (usual or paramagnetic) influences flux penetration and enhances the dissipation of heat, causing anomalous vortex configurations.

期刊介绍： The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
