Parametric oscillation, frequency mixing and injection locking of strongly coupled nanomechanical resonator modes
Maximilian J. Seitner, Mehdi Abdi, Alessandro Ridolfo +2
We study locking phenomena of two strongly coupled, high-quality factor nanomechanical resonator modes subject to a common parametric drive at a single drive frequency. By controll…
Current-phase relation of ballistic graphene Josephson junctions
Gaurav Nanda, Juan Luis Aguilera-Servin, Péter Rakyta +7
The current-phase relation (CPR) of a Josephson junction (JJ) determines how the supercurrent evolves with the superconducting phase difference across the junction. Knowledge of th…
Randomness via infinite computation and effective descriptive set theory
Merlin Carl, Philipp Schlicht
We study randomness beyond -randomness and its Martin-Löf type variant, introduced in \cite{MR2340241} and further studied in \cite{Continuous-higher-randomness}. The class…
A note on the triangle inequality for the Jaccard distance
Sven Kosub
Two simple proofs of the triangle inequality for the Jaccard distance in terms of nonnegative, monotone, submodular functions are given and discussed.
Coherent back and forward scattering peaks in the quantum kicked rotor
Gabriel Lemarié, Cord A. Müller, David Guéry-Odelin +1
We propose and analyze an experimental scheme using the quantum kicked rotor to observe the newly-predicted coherent forward scattering peak together with its long-known twin broth…
Noninteger-spin magnonic excitations in untextured magnets
Akashdeep Kamra, Utkarsh Agrawal, Wolfgang Belzig
Interactions are responsible for intriguing physics, e.g. emergence of exotic ground states and excitations, in a wide range of systems. Here we theoretically demonstrate that dipo…
