Kavli Affiliate: Ya M. Blanter | First 5 Authors: J. D. P. Machado, Ya. M. Blanter, , , | Summary: Phenomena such as state-swap, quadrature squeezing, entanglement and violation of entanglement inequalities are frequently reported to occur in quantum systems only. It is shown here that these effects can also occur in cholesteric liquid crystals […]
Kavli Affiliate: Gijsje Koenderink | First 5 Authors: Jose Alvarado, Luca Cipelletti, Gijsje Koenderink, , | Summary: Cells and tissues have the remarkable ability to actively generate the forces required to change their shape. This active mechanical behavior is largely mediated by the actin cytoskeleton, a crosslinked network of actin filaments that is contracted by […]
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 […]
