An Ising Hamiltonian Solver using Stochastic Phase-Transition Nano- Oscillators

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom | First 5 Authors: Sourav Dutta, Abhishek Khanna, Adou S. Assoa, Hanjong Paik, Darrell Schlom | Summary: Computationally hard problems, including combinatorial optimization, can be mapped into the problem of finding the ground-state of an Ising Hamiltonian. Building physical systems with collective computational ability and distributed parallel processing capability can accelerate […]

Microtextures in the Chelyabinsk impact breccia reveal the history of Phosphorus-Olivine-Assemblages in chondrites

Posted by dbos Caltech

Kavli Affiliate: Paul D. Asimow | First 5 Authors: Craig R. Walton, Ioannis Baziotis, Ana Černok, Oliver Shorttle, Paul D. Asimow | Summary: The geochemistry and textural associations of chondritic phosphate minerals can provide insights into the geological histories of parental asteroids, but the processes governing their formation and deformation remain poorly constrained. Here, we […]

Surface wave non-reciprocity via time-modulated metamaterials

Posted by klaurent Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Antonio Palermo, Paolo Celli, Behrooz Yousefzadeh, Chiara Daraio, Alessandro Marzani | Summary: We investigate how Rayleigh waves interact with modulated resonators located on the free surface of a semi-infinite elastic medium. We begin by studying the dynamics of a single resonator with time-modulated stiffness. In particular, we […]

Points2Surf: Learning Implicit Surfaces from Point Cloud Patches

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Philipp Erler, Paul Guerrero, Stefan Ohrhallinger, Michael Wimmer, Niloy J. Mitra | Summary: A key step in any scanning-based asset creation workflow is to convert unordered point clouds to a surface. Classical methods (e.g., Poisson reconstruction) start to degrade in the presence of noisy and partial scans. […]

Band gap renormalization, carrier mobilities, and the electron-phonon self-energy in crystalline naphthalene

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Florian Brown-Altvater, Gabriel Antonius, Tonatiuh Rangel, Matteo Giantomassi, Claudia Draxl | Summary: Organic molecular crystals are expected to feature appreciable electron-phonon interactions that influence their electronic properties at zero and finite temperature. In this work, we report first-principles calculations and an analysis of the electron-phonon self-energy […]

Nanoscale axial position and orientation measurement of hexagonal boron nitride quantum emitters using a tunable nanophotonic environment

Posted by klaurent Caltech

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Pankaj K. Jha, Hamidreza Akbari, Yonghwi Kim, Souvik Biswas, Harry A. Atwater | Summary: Color centers in hexagonal boron nitride (hBN) have emerged as promising candidates for single-photon emitters (SPEs) due to their bright emission characteristics at room temperature. In contrast to mono- and few-layered hBN, […]
