Highly-sensitive superconducting circuits at ~700 kHz with tunable quality factors for image-current detection of single trapped antiprotons
H. Nagahama, G. Schneider, A. Mooser +14
We developed highly-sensitive image-current detection systems based on superconducting toroidal coils and ultra-low noise amplifiers for non-destructive measurements of the axial f…
Scattering of twisted electron wave-packets by atoms in the Born approximation
D. V. Karlovets, G. L. Kotkin, V. G. Serbo +1
The potential scattering of electrons carrying non--zero quanta of the orbital angular momentum (OAM) is studied in a framework of the generalized Born approximation, developed in…
Nuclear excitation by two-photon electron transition
A. V. Volotka, A. Surzhykov, S. Trotsenko +3
A new mechanism of nuclear excitation via two-photon electron transitions (NETP) is proposed and studied theoretically. As a generic example, detailed calculations are performed fo…
Stochastic phase slips in toroidal Bose-Einstein condensates
Kyrylo Snizhko, Karyna Isaieva, Yevhenii Kuriatnikov +3
Motivated by recent experiments we study the influence of thermal noise on the phase slips in toroidal Bose-Einstein condensates with a rotating weak link. We derive a generalized…
A transportable optical lattice clock with uncertainty
S. B. Koller, J. Grotti, St. Vogt +5
We present a transportable optical clock (TOC) with Sr. Its complete characterization against a stationary lattice clock resulted in a systematic uncertainty of ${7.4 \times…
Nonequilibrium mesoscopic conductance fluctuations as the origin of 1/f noise in epitaxial graphene
Cay-Christian Kalmbach, Franz Josef Ahlers, Jürgen Schurr +6
We investigate the 1/f noise properties of epitaxial graphene devices at low temperatures as a function of temperature, current and magnetic flux density. At low currents, an expon…
