Kavli Affiliate: Chiara Daraio | First 5 Authors: Liwei Wang, Jagannadh Boddapati, Ke Liu, Ping Zhu, Chiara Daraio | Summary: Mechanical cloaks are materials engineered to manipulate the elastic response around objects to make them indistinguishable from their homogeneous surroundings. Typically, methods based on material-parameter transformations are used to design optical, thermal and electric cloaks. […]
Kavli Affiliate: James J. Bock | First 5 Authors: Shubh Agrawal, Bryan Steinbach, James J. Bock, Clifford Frez, Lorenzo Minutolo | Summary: We demonstrate strong negative electrothermal feedback accelerating and linearizing the response of a thermal kinetic inductance detector (TKID). TKIDs are a proposed highly multiplexable replacement to transition-edge sensors and measure power through the […]

Dean | Summary: Optical nonlinear functions are crucial for various applications in integrated photonics, such as all-optical information processing, photonic neural networks and on-chip ultrafast light sources. Due to the weak nonlinearities in most integrated photonic platforms, […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Tianzhe Zheng, Andrei Faraon, | Summary: Photonic topology optimization is a technique used to find the electric permittivity distribution of a device that optimizes an electromagnetic figure-of-merit. Two common techniques are used: continuous density-based optimizations that optimize a grey-scale permittivity defined over a […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Harald Putterman, Joseph Iverson, Qian Xu, Liang Jiang, Oskar Painter | Summary: Biased-noise qubits are a promising candidate for realizing hardware efficient fault-tolerant quantum computing. One promising biased-noise qubit is the Kerr cat qubit, which has recently been demonstrated experimentally. Despite various unique advantages of Kerr cat […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Harald Putterman, Joseph Iverson, Qian Xu, Liang Jiang, Oskar Painter | Summary: Protected qubits such as the 0-$pi$ qubit, and bosonic qubits including cat qubits and GKP qubits offer advantages for fault-tolerance. Some of these protected qubits (e.g., 0-$pi$ qubit and Kerr cat qubit) are stabilized by […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Mingchen Liu, Robert M. Gray, Arkadev Roy, Charles R. Markus, Alireza Marandi | Summary: Dual-comb spectroscopy has been proven a powerful tool in molecular characterization, which remains challenging to implement in the mid-infrared (MIR) region due to difficulties in the realization of two mutually locked comb sources […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Antonio Palermo, Behrooz Yousefzadeh, Chiara Daraio, Alessandro Marzani, | Summary: We investigate the propagation of Rayleigh waves in a half-space coupled to a nonlinear metasurface. The metasurface consists of an array of nonlinear oscillators attached to the free surface of a homogeneous substrate. We describe, analytically and […]
