Electrodynamics of Quantum-Critical Conductors and Superconductors
Uwe S. Pracht
This thesis presents and discusses optical low-temperature experiments on disordered NbN, granular Al thin-films, and the heavy-fermion compound CeCoIn5, offering a unified picture…
Optical signatures of the superconducting Goldstone mode in granular aluminum: experiments and theory
Uwe S. Pracht, Tommaso Cea, Nimrod Bachar +7
Recent advances in the experimental growth and control of disordered thin films, heterostructures, and interfaces provide a fertile ground for the observation and characterisation…
Superconducting Energy Scales and Anomalous Dissipative Conductivity in Thin Films of Molybdenum Nitride
Julian Simmendinger, Uwe S. Pracht, Lena Daschke +4
We report investigations of molybdenum nitride (MoN) thin films with different thickness and disorder and with superconducting transition temperature 9.89 K 2.78 K. U…
THz conductivity of SrCaRuO
Diana Geiger, Uwe S. Pracht, Martin Dressel +4
We investigate the optical conductivity of SrCaRuO across the ferromagnetic to paramagnetic transition that occurs at . The thin films were grown by metalorg…
Charge Carrier Dynamics of the Heavy Fermion Metal CeCoIn Probed by THz Spectroscopy
Uwe S. Pracht, Julian Simmendinger, Martin Dressel +8
We discuss the charge carrier dynamics of the heavy-fermion compound CeCoIn in the metallic regime measured by means of quasi-optical THz spectroscopy. The transmittance of ele…
Shaping a superconducting dome: Enhanced Cooper-pairing versus suppressed phase coherence in coupled aluminum nanograins
Uwe S. Pracht, Nimrod Bachar, Lara Benfatto +4
Deterministic enhancement of the superconducting (SC) critical temperature is a long-standing goal in material science. One strategy is engineering a material at the nanomete…
