The magnitude and the temperature dependence of the superconducting order parameter $\Delta(T)$ of
single-crystals of Cd$_2$Re$_2$O$_7$ ($T_c$ = 1.02~K) was measured using point-contact
spectroscopy. In order to fit the conductance spectra and to extract the order parameter
at different temperatures we generalized
the Blonder-Tinkham-Klapwijk theory by including the self-energy of the...

Charge ordered phases are now found in a wide range of underdoped cuprate high temperature superconductors. The relationship between these phases and nearby antiferromagnetic, superconducting, and pseudogap phases is not well established. However, the close proximity of the different phases suggests the possibility of nontrivial mixed states comprising multiple coexisting phases. In this...

Recent angle-resolved photoemission experiments have observed a proximity-induced superconducting gap in the helical surface states of the 3D topological insulator Bi$_2$Se$_3$, when a thin film of the latter is grown on a superconducting NbSe$_2$ substrate. The superconducting coherence peaks are strongly suppressed when the topological insulator thin film is doped with magnetic Mn...

In recent years, the two dimensional electron gases ($2$DEG) that form at some oxide interfaces have attracted worldwide attention due to their fascinating properties such as
conductivity, superconductivity, and magnetic order.
Here, we build a theoretical model for exploring the electronic properties of the $2$DEG at LaAlO$_3$/SrTiO$_3$ interfaces considering the strong dependence of...

The Ginzburg-Landau model for superconductivity provides a phenomenological description of superconductors near the critical temperature where a phase transition between superconducting and regular states occurs. The model has a single dimensionless free parameter, $\kappa$, that has a critical value separating type I and type II superconductors. Of particular interest are the vortex solutions...

There has been a resurgence of interest in superconductivity since the discovery of high temperature superconductivity in the cuprates. As a result, a variety of new superconductors with high transition temperatures and other interesting properties have been discovered. The muon spin rotation/relaxation ($\mu$SR) technique is an extremely sensitive probe of magnetic fields in materials and...
