Interfering trajectories in a ballistic Andreev cavity
Pankaj Mandal, Marcel Kaschper, Fernando Dominguez +9
The conventional description of transport through the interface between a normal conductor and a superconductor reduces the system to a one-dimensional problem treating Andreev ref…
Wiedemann-Franz behavior at the Weyl points in compressively strained HgTe
Abu Alex Aravindnath, Yi-Ju Ho, Fabian Schmitt +6
Weyl semimetals, with their unique electronic band structure, have drawn significant interest for their potential to explore quantum anomalies in condensed matter systems. In this…
Femtosecond photocurrents by the Dresselhaus bulk spin-galvanic effect in an inversion-asymmetric ferromagnet
Junwei Tong, Zdenek Kaspar, Afnan Alostaz +18
We study ultrafast photocurrents in thin films of a model ferromagnetic metal with broken bulk inversion symmetry, the half-metallic Heusler compound NiMnSb, following excitation w…
Phase-dependent supercurrent and microwave dissipation of HgTe quantum well Josephson junctions
Wei Liu, Stanislau U. Piatrusha, Lena Fürst +4
We measured the microwave response of a HgTe quantum well Josephson junction embedded into an RF SQUID loop which is inductively coupled to a superconducting resonator. The side-co…
Highly efficient broadband THz upconversion with Dirac materials
Tatiana A. Uaman Svetikova, Igor Ilyakov, Alexey Ponomaryov +16
The use of the THz frequency domain in future network generations offers an unparalleled level of capacity, which can enhance innovative applications in wireless communication, ana…
Zero external magnetic field quantum standard of resistance at the 10-9 level
D. K. Patel, K. M. Fijalkowski, M. Kruskopf +10
The quantum anomalous Hall effect holds promise as a disruptive innovation in condensed matter physics and metrology, as it gives access to Hall resistance quantization in terms of…
