Rise and Fall of Landau's Quasiparticles While Approaching the Mott Transition
Andrej Pustogow, Yohei Saito, Anja Löhle +5
Landau suggested that the low-temperature properties of metals can be understood in terms of long-lived quasiparticles with all complex interactions included in Fermi-liquid parame…
Phase coexistence at the first-order Mott-transition revealed by pressure-dependent dielectric spectroscopy of -(BEDT-TTF)Cu(CN)
R. Rösslhuber, A. Pustogow, E. Uykur +7
The dimer Mott insulator -(BEDT-TTF)Cu(CN) can be tuned into a metallic and superconducting state upon applying pressure of 1.5 kbar and more. We have performed diel…
Low-Temperature Dielectric Anomalies at the Mott Insulator-Metal Transition
A. Pustogow, R. Rösslhuber, Y. Tan +10
The correlation-driven Mott transition is commonly characterized by a drop in resistivity across the insulator-metal phase boundary; yet, the complex permittivity provides a deeper…
Free-carrier dynamics in AuPb probed by optical conductivity measurements
R. Kemmler, R. Hübner, A. Löhle +5
We measured the optical reflectivity of the Dirac material AuPb in a broad frequency range (30 - 48 000 cm) for temperatures between 9 and 300 K. The optical conductiv…
Optical conductivity of the Weyl semimetal NbP
D. Neubauer, A. Yaresko, Weiwu Li +7
The optical properties of (001)-oriented NbP single crystals have been studied in a wide spectral range from 6 meV to 3 eV from room temperature down to 10 K. The itinerant carrier…
Electronic Scattering Effects in Europium-Based Iron Pnictides
S. Zapf, D. Neubauer, K. W. Post +8
In a comprehensive study, we investigate the electronic scattering effects in EuFe(AsP) by using Fourier-transform infrared spectroscopy. In spite of the…
