Kavli Affiliate: Matthew Fisher | First 5 Authors: Arman Maesumi, Dylan Hu, Krishi Saripalli, Vladimir G. Kim, Matthew Fisher | Summary: Procedural noise is a fundamental component of computer graphics pipelines, offering a flexible way to generate textures that exhibit "natural" random variation. Many different types of noise exist, each produced by a separate algorithm. […]
Kavli Affiliate: David Gross | First 5 Authors: Vahideh Eshaghian, Sören Wilkening, Johan Åberg, David Gross, | Summary: Many search-based quantum algorithms that achieve a theoretical speedup are not practically relevant since they require extraordinarily long coherence times, or lack the parallelizability of their classical counterparts.This raises the question of how to divide computational tasks […]
Kavli Affiliate: Leon Balents | First 5 Authors: Zhuoliang Ni, Urban Seifert, Amanda V. Haglund, Nan Huang, David G. Mandrus | Summary: In a collinear antiferromagnet, spins tend to cant towards the direction of an applied magnetic field, thereby decreasing the energy of the system. The canting angle becomes negligible when the magnetic field is […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Alexander D. White, Geun Ho Ahn, Kasper Van Gasse, Richard Luhtaru, Joel Guo | Summary: Rapid progress in photonics has led to an explosion of integrated devices that promise to deliver the same performance as table-top technology at the nanoscale; heralding the next generation of optical […]

Morin | Summary: Rapid progress in photonics has led to an explosion of integrated devices that promise to deliver the same performance as table-top technology at the nanoscale; heralding the next generation of optical […]
Kavli Affiliate: David Gross | First 5 Authors: Carsten Hartmann, Philipp C. Böttcher, David Gross, Dirk Witthaut, | Summary: Synchronization is essential for the operation of AC power systems: All generators in the power grid must rotate with fixed relative phases to enable a steady flow of electric power. Understanding the conditions for and the […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Hirsh Kamakari, Jiace Sun, Yaodong Li, Jonathan J. Thio, Tanvi P. Gujarati | Summary: Quantum systems subject to random unitary evolution and measurements at random points in spacetime exhibit entanglement phase transitions which depend on the frequency of these measurements. Past work has experimentally observed […]
Kavli Affiliate: Leon Balents | First 5 Authors: Léo Mangeolle, Lucile Savary, Leon Balents, , | Summary: We systematically derive the quantum kinetic equation in full phase space for any quadratic hamiltonian of bosonic fields, including in the absence of translational invariance. This enables the treatment of boundaries, inhomogeneous systems and states with non-trivial textures, […]
Kavli Affiliate: Leon Balents | First 5 Authors: Clifford J. Allington, Carina A. Belvin, Urban F. P. Seifert, Mengxing Ye, Tommy Tai | Summary: The control of antiferromagnets with ultrashort optical pulses has emerged as a prominent field of research. Tailored laser excitation can launch coherent spin waves at terahertz frequencies, yet a comprehensive description […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Logan J. Prust, Hila Glanz, Lars Bildsten, Hagai B. Perets, Friedrich K. Roepke | Summary: We carry out three-dimensional computations of the accretion rate onto an object (of size $R_{rm sink}$ and mass $m$) as it moves through a uniform medium at a subsonic speed $v_{infty}$. The […]
