Kavli Affiliate: Ya M. Blanter | First 5 Authors: J. D. P. Machado, R. J. Slooter, Ya. M. Blanter, , | Summary: We analyze quantum effects occurring in optomechanical systems where the coupling between an optical mode and a mechanical mode is quadratic in displacement (membrane-in-the-middle geometry). We show that it is possible to observe […]
Kavli Affiliate: Ya M. Blanter | First 5 Authors: J. D. P. Machado, Ya. M. Blanter, , , | Summary: Sideband asymmetry in cavity optomechanics has been explained by particle creation and annihilation processes, which bestow an amplitude proportional to ‘n+1’ and ‘n’ excitations to each of the respective sidebands. We discuss the issues with […]
Kavli Affiliate: Yu V. Nazarov | First 5 Authors: F. Vischi, M. Carrega, E. Strambini, S. D’Ambrosio, F. S. Bergeret | Summary: We present an exhaustive theoretical analysis of a double-loop Josephson proximity interferometer, as the one recently realized by Strambini et al. for the control of the Andreev spectrum via an external magnetic field. […]
Kavli Affiliate: Michael T. Wimmer | First 5 Authors: Diana Car, Sonia Conesa-Boj, Hao Zhang, Roy L. M. Op het Veld, Michiel W. A. de Moor | Summary: Majorana zero modes (MZMs), prime candidates for topological quantum bits, are detected as zero bias conductance peaks (ZBPs) in tunneling spectroscopy measurements. Implementation of a narrow and […]
Kavli Affiliate: Yu V. Nazarov | First 5 Authors: E. Strambini, S. D’Ambrosio, F. Vischi, F. S. Bergeret, Yu. V. Nazarov | Summary: Multi-terminal superconducting Josephson junctions based on the proximity effect offer the bright opportunity to tailor non trivial quantum states in nanoscale weak-links. These structures can realize exotic topologies in multidimensions as, for […]
Kavli Affiliate: Yu V. Nazarov | First 5 Authors: C. Padurariu, T. Jonckheere, J. Rech, R. Mélin, D. Feinberg | Summary: We describe the proximity effect in a short disordered metallic junction between three superconducting leads. Andreev bound states in the multi-terminal junction may cross the Fermi level. We reveal that for a quasi-continuous metallic […]
Kavli Affiliate: Viatcheslav V. Dobrovitski | First 5 Authors: Demitry Farfurnik, Andrey Jarmola, Linh M. Pham, Zhi-Hui Wang, Viatcheslav V. Dobrovitski | Summary: We demonstrate significant improvements of the spin coherence time of a dense ensemble of nitrogen-vacancy (NV) centers in diamond through optimized dynamical decoupling (DD). Cooling the sample down to $77$ K suppresses […]
Kavli Affiliate: Martin Depken | First 5 Authors: Martin Depken, Juan M. R. Parrondo, Stephan W. Gril, , | Summary: Both genomic stability and sustenance of day-to-day life rely on efficient and accurate readout of the genetic code. Single-molecule experiments show that transcription and replication are highly stochastic and irregular processes, with the polymerases frequently […]
Kavli Affiliate: Kobus Kuipers | First 5 Authors: Marko Spasenovic, Daryl M. Beggs, Philippe Lalanne, Thomas F. Krauss, L. | Summary: We measure the spatial extent of individual localized photonic states in a slow-light photonic crystal waveguide. The size of the states is measured by perturbing each state individually through a local electromagnetic interaction with […]
Kavli Affiliate: Jos W. Zwanikken | First 5 Authors: Chantal Valeriani, Philip J. Camp, Jos W. Zwanikken, René van Roij, Marjolein Dijkstra | Summary: The association of ions in electrolyte solutions at very low concentration and low temperature is studied using computer simulations and quasi-chemical ion-pairing theory. The specific case of the restricted primitive model […]
