Constraining continuous topology optimizations to discrete solutions for photonic applications

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 […]

Colored Kerr cat qubits

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 […]

Stabilizing a Bosonic Qubit using Colored Dissipation

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 […]

Critical properties of quantum three- and four-state Potts models with boundaries polarized along the transverse field

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Natalia Chepiga, , , , | Summary: By computing the low-lying energy excitation spectra with the density matrix renormalization group algorithm we confirm the boundary conformal field theory predictions for the three-state Potts minimal model in 1+1D with boundaries polarized in the direction of the transverse field. […]

Mid-Infrared Cross-Comb Spectroscopy

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 […]

Rayleigh wave propagation in nonlinear metasurfaces

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 […]

Developmental Stage Classification of Embryos Using Two-Stream Neural Network with Linear-Chain Conditional Random Field

Kavli Affiliate: Daniel Needleman | First 5 Authors: Stanislav Lukyanenko, Won-Dong Jang, Donglai Wei, Robbert Struyven, Yoon Kim | Summary: The developmental process of embryos follows a monotonic order. An embryo can progressively cleave from one cell to multiple cells and finally transform to morula and blastocyst. For time-lapse videos of embryos, most existing developmental […]

Learning intermolecular forces at liquid-vapor interfaces

Kavli Affiliate: David T. Limmer | First 5 Authors: Samuel P. Niblett, Mirza Galib, David T. Limmer, , | Summary: By adopting a perspective informed by contemporary liquid state theory, we consider how to train an artificial neural network potential to describe inhomogeneous, disordered systems. We find that neural network potentials based on local representations […]

Quasiparticle kinetic theory for Calogero models

Kavli Affiliate: Joel E. Moore | First 5 Authors: Vir B. Bulchandani, Manas Kulkarni, Joel E. Moore, Xiangyu Cao, | Summary: We show that the quasiparticle kinetic theory for quantum and classical Calogero models reduces to the free-streaming Boltzmann equation. We reconcile this simple emergent behaviour with the strongly interacting character of the model by […]
