We have measured the magnetic-flux expulsion of a superconducting superlattice and related it to the Meissner penetration depth. The temperature dependence of the penetration depth is in quantitative agreement with theoretical expectation based on mean-field theory. The zerotemperature penetration depth is found in excellent, quantitative agreement without adjustable parameters with theoretical...

In this paper we describe a novel spectroscopic closed loop control system capable of stabilizing the penetration depth during laser welding processes by controlling the laser power. Our novel approach is to analyze the optical emission from the laser generated plasma plume above the keyhole, to calculate its electron temperature as a process-monitoring signal. Laser power has been controlled b...

The recently discovered kagome metal series $A$V$_3$Sb$_5$ ($A$=K, Rb, Cs) exhibits topologically nontrivial band structures, chiral charge order and superconductivity, presenting a unique platform for realizing exotic electronic states. nature of the superconducting state corresponding pairing symmetry are key questions that demand experimental clarification. Here, using technique based on tun...

In this work we study thermodynamic manifestations of the quantum criticality in multiband unconventional superconductors. As a guiding example consider scenario magnetic critical point model that captures superconductivity coexistence with spin-density wave. We show situations when superconducting order parameter has incidental nodes at isolated points, fluctuations lead to renormalization rel...

We present a fast penetration depth estimation algorithm between deformable polyhedral objects. We assume the continuum of non-rigid models are discretized using standard techniques, such as finite element or finite difference methods. As the objects deform, the distance fields are deformed accordingly to estimate penetration depth, allowing enforcement of non-penetration constraints between tw...
