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…
