Transition metal nitride (TMN) thin films exhibit outstanding physical, chemical, and
mechanical properties, making them best suitable for a wide variety of applications. The …

Recent experiments with strong THz fields in both conventional and unconventional
superconductors have clearly evidenced a marked third-harmonic generation below the …

Recently, the THz spectroscopy has been efficiently used to investigate varieties of quantum
materials, including superconductors, novel magnetic, and topological materials. These …

Recent progress in superconductor electronics fabrication has enabled single-flux-quantum
(SFQ) digital circuits with close to one million Josephson junctions (JJs) on 1-cm 2 chips …

In order to develop design rules for novel nitride-based coatings, we investigate trends in
thermodynamic, structural, elastic, and electronic properties of Mo 1− x Ta x N single-phase …

Recent advances in the experimental growth and control of disordered thin films,
heterostructures, and interfaces provide fertile ground for the observation and …

The low-energy optical conductivity of conventional superconductors is usually well
described by Mattis-Bardeen (MB) theory, which predicts the onset of absorption above an …

The tunneling density of states in dirty s-wave superconductors is often well described by the
phenomenological Dynes formula. Recently we have shown that this formula can be …

Recently, a generic model was proposed for the single-particle properties of gapless
superconductors with simultaneously present pair-conserving and pair-breaking impurity …

We have built a terahertz dispersive Fourier transform spectrometer [Birch, Microchim. Acta
93, 105–122 (1987)] to study frequency properties of superconducting films used for …
