Critical slowing down of fermions near a magnetic quantum phase transition
Chia-Jung Yang, Kristin Kliemt, Cornelius Krellner +3
A universal phenomenon in phase transitions is critical slowing down (CSD) - systems, after an initial perturbation, take an exceptionally long time to return to equilibrium. It is…
Terahertz Conductivity of Heavy-fermion Systems from Time-resolved Spectroscopy
Chia-Jung Yang, Shovon Pal, Farzaneh Zamani +6
The Drude model describes the free-electron conduction in simple metals, governed by the freedom that the mobile electrons have within the material. In strongly correlated systems,…
Fermi volume evolution and crystal field excitations in heavy-fermion compounds probed by time-domain terahertz spectroscopy
Shovon Pal, Christoph Wetli, Farzaneh Zamani +4
We measure the quasiparticle weight in the heavy-fermion compound CeCuAu () by time-resolved THz spectroscopy for temperatures from 2 up to 300\,K. This me…
Unveiling spectral purity and tunability of terahertz quantum cascade laser sources based on intra-cavity difference frequency generation
Luigi Consolino, Seungyong Jung, Annamaria Campa +10
Terahertz sources based on intra-cavity difference-frequency generation in mid-infrared quantum cascade lasers (THz DFG-QCLs) have recently emerged as the first monolithic electric…
Time-resolved collapse and revival of the Kondo state near a quantum phase transition
Ch. Wetli, S. Pal, J. Kroha +5
One of the most successful paradigms of many-body physics is the concept of quasiparticles: excitations in strongly interacting matter behaving like weakly interacting particles in…
Nanoscale nonlinear effects in Erbium-implanted Yttrium Orthosilicate
Nadezhda Kukharchyk, Stepan Shvarkov, Sebastian Probst +11
Doping of substrates at desired locations is a key technology for spin-based quantum memory devices. Focused ion beam implantation is well-suited for this task due to its high spac…
