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: Austin Minnich | First 5 Authors: Austin J. Minnich, , , , | Summary: Boundary scattering of thermal phonons in thin solid films is typically analyzed using Fuchs-Sondheimer theory, which provides a simple equation to calculate the reduction of thermal conductivity as a function of the film thickness. However, this widely-used equation is […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Tian Zhong, Jonathan M. Kindem, Evan Miyazono, Andrei Faraon, | Summary: Quantum light-matter interfaces (QLMIs) connecting stationary qubits to photons will enable optical networks for quantum communications, precise global time keeping, photon switching, and studies of fundamental physics. Rare-earth-ion (REI) doped crystals are state-of-the-art materials for optical […]
Kavli Affiliate: Omar M. Yaghi | First 5 Authors: Nanette N. Jarenwattananon, Stefan Gloeggler, Trenton Otto, Arek Melkonian, William Morris | Summary: Over 85% of all chemical industry products are made using catalysts, with the overwhelming majority of these employing heterogeneous catalysts functioning at the gas-solid interface. Consequently, optimizing catalytic reactor design attracts much effort. […]
Kavli Affiliate: Austin Minnich | First 5 Authors: Austin J. Minnich, , , , | Summary: Transient grating spectroscopy has emerged as a useful technique to study thermal phonon transport because of its ability to perform thermal measurements over length scales comparable to phonon mean free paths (MFPs). While several prior works have performed theoretical […]
Kavli Affiliate: Anna V. Shneidman | First 5 Authors: Ian B. Burgess, Navid Abedzadeh, Theresa M. Kay, Anna V. Shneidman, Derek J. Cranshaw | Summary: Although complex, hierarchical nanoscale geometries with tailored degrees of disorder are commonly found in biological systems, few simple self-assembly routes to fabricating synthetic analogues have been identified. We present two […]
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: Keith C. Schwab | First 5 Authors: Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer, Peter F. Barker, Angelo Bassi | Summary: Do the laws of quantum physics still hold for macroscopic objects – this is at the heart of Schr"odinger’s cat paradox – or do gravitation or yet unknown effects set a limit for […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Miguel Molerón, Chiara Daraio, , , | Summary: Lenses that can collect the perfect image of an object must restore propagative and evanescent waves. However, for efficient information transfer, e.g., in compressed sensing, it is often desirable to detect only the fast spatial variations of the wave […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Alireza Marandi, Zhe Wang, Kenta Takata, Robert L. Byer, Yoshihisa Yamamoto | Summary: Finding the ground states of the Ising Hamiltonian [1] maps to various combinatorial optimization problems in biology, medicine, wireless communications, artificial intelligence, and social network. So far no efficient classical and quantum algorithm is […]
