Zero-phonon line emission of single photon emitters in helium-ion treated MoS
Katja Barthelmi, Tomer Amit, Mirco Troue +13
We explore the zero-phonon line of single photon emitters in helium-ion treated monolayer MoS, which are currently understood in terms of single sulfur-site vacancies. By compa…
Entanglement-verified time distribution in a metropolitan network
Mohammed K. Alqedra, Samuel Gyger, Katharina D. Zeuner +4
The precise synchronization of distant clocks is a fundamental requirement for a wide range of applications. Here, we experimentally demonstrate a novel approach of quantum clock s…
Low-Temperature Heat Transport under Phonon Confinement in Nanostructures
M. Sidorova, A. D. Semenov, A. Zaccone +5
Heat transport in bulk materials is well described using the Debye theory of 3D vibrational modes (phonons) and the acoustic match model. However, in cryogenic nanodevices, phonon…

Current crowding in nanoscale superconductors within the Ginzburg-Landau model
Mattias Jönsson, Robert Vedin, Samuel Gyger +5
The current density in a superconductor with turnarounds or constrictions is non-uniform due to a geometrical current crowding effect. This effect reduces the critical current in t…
