Indium tin oxide films meet circular Rydberg atoms: prospects for novel quantum simulation schemes
Florian Meinert, Christian Hölzl, Mehmet Ali Nebioglu +4
Long-lived circular Rydberg atoms are picking up increasing interest for boosting coherence times in Rydberg-based quantum simulation. We elaborate a novel approach to stabilize ci…
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…
Characterization of harmonic modes and parasitic resonances in multi-mode superconducting coplanar resonators
Cenk Beydeda, Konstantin Nikolaou, Marius Tochtermann +8
Planar superconducting microwave transmission line resonators can be operated at multiple harmonic resonance frequencies. This allows covering wide spectral regimes with high sensi…
Signatures of phase transitions in the microwave response of YbRh2Si2
Katja Parkkinen, Martin Dressel, Kristin Kliemt +4
We used a spectroscopic microwave technique utilizing superconducting stripline resonators at frequencies between 3 GHz and 15 GHz to examine the charge dynamics of YbRh2Si2 at tem…
Signatures of Dynes superconductivity in the THz response of ALD-grown NbN thin films
Frederik Bolle, Yayi Lin, Ozan Saritas +6
The frequency-dependent complex optical conductivity reflects key properties of superconductors, such as the energy gap in the density of states (DOS) and the superfluid density. F…
Gapped magnetic ground state in the spin-liquid candidate -(BEDT-TTF)Ag(CN) suggested by magnetic spectroscopy
Sudip Pal, Björn Miksch, Hans-Albrecht Krug von Nidda +10
The nature of the magnetic ground state of highly frustrated systems remained puzzling to this day. Here, we have performed multifrequency electron spin resonance (ESR) measurement…
