A long-lived solid-state optical quantum memory for high-rate quantum repeaters

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Mohsen Falamarzi Askarani, Antariksha Das, Jacob H. Davidson, Gustavo C. Amaral, Neil Sinclair | Summary: We argue that long optical storage times are required to establish entanglement at high rates over large distances using memory-based quantum repeaters. Triggered by this conclusion, we investigate the $^3$H$_6$ $leftrightarrow$ $^3$H$_4$ […]

Supersymmetry and multicriticality in a ladder of constrained fermions

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, Jiří Minář, Kareljan Schoutens, , | Summary: Supersymmetric lattice models of constrained fermions are known to feature exotic phenomena such as superfrustration, with an extensive degeneracy of ground states, the nature of which is however generally unknown. Here we address this issue by considering a […]

Multiplet supercurrent in Josephson tunneling circuits

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: André Melo, Valla Fatemi, Anton R. Akhmerov, , | Summary: The multi-terminal Josephson effect allows DC supercurrent to flow at finite commensurate voltages. Existing proposals to realize this effect rely on nonlocal Andreev processes in superconductor-normal-superconductor junctions. However, this approach requires precise control over microscopic states […]

Chiral Anomaly Trapped in Weyl Metals: Nonequilibrium Valley Polarization at Zero Magnetic Field

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Pablo M. Perez-Piskunow, Nicandro Bovenzi, Anton R. Akhmerov, Maxim Breitkreiz, | Summary: In Weyl semimetals the application of parallel electric and magnetic fields leads to valley polarization — an occupation disbalance of valleys of opposite chirality — a direct consequence of the chiral anomaly. In this […]
