Kavli Affiliate: Lars Bildsten | First 5 Authors: Logan J. Prust, Gabriel Kumar, Lars Bildsten, , | Summary: Type Ia supernovae are triggered by accretion onto a white dwarf from a companion which is most likely Roche lobe-filling at the time of the explosion. The collision between the ejecta and a surviving companion carves out […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Sanghyun Son, Matheus Gadelha, Yang Zhou, Matthew Fisher, Zexiang Xu | Summary: Recent probabilistic methods for 3D triangular meshes capture diverse shapes by differentiable mesh connectivity, but face high computational costs with increased shape details. We introduce a new differentiable mesh processing method in 2D and 3D […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Yiming Pang, Joshua E. Castro, Trevor J. Steiner, Liao Duan, Noemi Tagliavacche | Summary: Integrated photonic microresonators have become an essential resource for generating photonic qubits for quantum information processing, entanglement distribution and networking, and quantum communications. The pair generation rate is enhanced by reducing the […]
Kavli Affiliate: Matthew Fisher | First 5 Authors: Aditya Ganeshan, Thibault Groueix, Paul Guerrero, Radomír Měch, Matthew Fisher | Summary: Pattern images are everywhere in the digital and physical worlds, and tools to edit them are valuable. But editing pattern images is tricky: desired edits are often programmatic: structure-aware edits that alter the underlying program […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Stephen W. Yan, Diego Barberena, Matthew P. A. Fisher, Sagar Vijay, | Summary: We investigate a quantum dynamical phase transition induced by the competition between local unitary evolution and dissipation in a qubit chain with a strong, on-site $mathbb{Z}_2$ symmetry. While the steady-state of this […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Theodore J. Morin, Mingxiao Li, Federico Camponeschi, Hou Xiong, Deven Tseng | Summary: Heterogeneous integration of GaAs-based lasers with frequency doubling waveguides presents a clear path to scalable coherent sources in the so-called green gap, yet frequency doubling systems have so far relied on separately manufactured […]
Kavli Affiliate: Leon Balents | First 5 Authors: Zhenhao Song, Tessa Cookmeyer, Leon Balents, , | Summary: We study the driven-dissipative Bose-Hubbard model with all-to-all hopping and subject to incoherent pumping and decay, as is naturally probed in several recent experiments on excitons in WS2/WSe2 moir’e systems, as well as quantum simulators. By positing a […]
Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Diego Barberena, Matthew P. A. Fisher, , , | Summary: We study in detail the postselection problem in a specific model: bosons hopping on a lattice subjected to continuous local measurements of quadrature observables. We solve the model analytically and show that the postselection overhead […]
Kavli Affiliate: Leon Balents | First 5 Authors: Gu-Feng Zhang, Sheikh Rubaiat Ul Haque Kelson J. Kaj, Xiang Chen, Urban F. P. Seifert, Jingdi Zhang | Summary: Antiferromagnets exhibit rapid spin dynamics in a net zero magnetic background which enables novel spintronic applications and interrogation of many-body quantum phenomena. The layered antiferromagnet Sr$_2$IrO$_4$ hosts an […]
Kavli Affiliate: Mark J. Bowick | First 5 Authors: Jin-Sheng Wu, Roberto Abril Valenzuela, Mark J. Bowick, Ivan I. Smalyukh, | Summary: We study topologically stable defect structures in systems where the defect line classification in three dimensions and associated algebra of interactions (the fundamental group) are governed by the non-Abelian 8-element group, the quaternions […]
