Kavli Affiliate: Harry A. Atwater | First 5 Authors: Parker R. Wray, Harry A. Atwater, , , | Summary: We present a linear coordinate transform to expand the solution of scattering and emission problems into a basis of forward and backward directional vector harmonics. The transform provides intuitive algebraic and geometric interpretations of systems with […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Piero Chiappina, Jash Banker, Srujan Meesala, David Lake, Steven Wood | Summary: Coherent transduction of quantum states from the microwave to the optical domain can play a key role in quantum networking and distributed quantum computing. We present the design of a piezo-optomechanical device formed in a […]

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Merritt P. Losert, M. A. Eriksson, Robert Joynt, Rajib Rahman, Giordano Scappucci | Summary: Silicon/silicon-germanium heterostructures have many important advantages for hosting spin qubits. However, controlling the valley splitting (the energy splitting between the two low-lying conduction-band valleys) remains a critical challenge for ensuring qubit reliability. Broad […]
Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Yanyou Xie, Hil Fung Harry Cheung, Gregory D. Fuchs, , | Summary: In this work, we develop a nanoscale magnetic field sensor based on a spin-Hall nano-oscillator (SHNO) device. We fabricate constriction-based SHNO devices using Ni$_{81}$Fe$_{19}$/Au$_{0.25}$Pt$_{0.75}$ bilayer and use them to demonstrate quasi-DC sensing up to […]

Kavli Affiliate: David T. Limmer | First 5 Authors: Aditya N. Singh, David T. Limmer, , , | Summary: We present a time dependent variational method to learn the mechanisms of equilibrium reactive processes and efficiently evaluate their rates within a transition path ensemble. This approach builds off variational path sampling methodology by approximating the […]
Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Shuqiu Wang, Niall Kennedy, Kazuhiro Fujita, Shin-ichi Uchida, Hiroshi Eisaki | Summary: The primordial ingredient of cuprate superconductivity is the CuO$_2$ unit cell. Here, theoretical attention usually concentrates on the intra-atom Coulombic interactions dominating the $3d^9$ and $3d^{10}$ configurations of each copper ion. However, if […]
