Kavli Affiliate: Feng Wang | First 5 Authors: Aditya Bahulikar, Feng Wang, Mustafa Cenk Gursoy, Rodrick Kuate Defo, | Summary: We present a symmetry-agnostic topology optimization framework for photonic-crystal structures based on computation of the photonic density of states in a manner analogous to $Gamma$-point integration. We provide a generalization of the approach that allows […]
Kavli Affiliate: Peidong Yang | First 5 Authors: Jonah R. Adelman, Hugo Laurell, Lorenz Drescher, Han K. D. Le, Peidong Yang | Summary: The narrow bandgap semiconductor elemental tellurium (Te) has a unique electronic structure due to strong spin-orbit splitting and a lack of inversion symmetry of its helical lattice. Using broadband extreme ultraviolet core-level […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Petra Awad, Ting S. Li, Denis Erkal, Reynier F. Peletier, Kerstin Bunte | Summary: As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the clusters around the Galaxy. The morphology of these tails is […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nathan Jamieson, Aaron Smith, Meredith Neyer, Rahul Kannan, Enrico Garaldi | Summary: The growth of ionized hydrogen bubbles in the intergalactic medium around early luminous objects is a fundamental process during the Epoch of Reionization (EoR). In this study, we analyze bubble sizes and their evolution using […]
Kavli Affiliate: Ran Wang | First 5 Authors: Han Qing Yang, Jun Yan Dai, Hui Dong Li, Lijie Wu, Meng Zhen Zhang | Summary: The programmable metasurface is regarded as one of the most promising transformative technologies for next-generation wireless system applications. Due to the lack of effective perception ability of the external electromagnetic environment, […]
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Julie Belleville, Prachi Thureja, Harry A. Atwater, , | Summary: We introduce a conceptual framework for a lensless imaging system which employs an active metasurface as a high-frequency, continuously tunable amplitude and phase modulation aperture, coupled to a discrete single-pixel detector. Using an array factor formalism, […]
Kavli Affiliate: Ann McDermott | Authors: Cassandra A Chartier, Virgil A Woods, Yunyao Xu, Anne E van Vlimmeren, Marko Jovanovic, Ann E McDermott, Daniel A Keedy and Neel H Shah | Summary: The rapid identification of protein-protein interactions has been significantly enabled by mass spectrometry (MS) proteomics-based methods, including affinity purification-MS, crosslinking-MS, and proximity-labeling proteomics. […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Kaloian D. Lozanov, Misao Sasaki, , , | Summary: We consider a scalar field theory with a Minkowski false vacuum and an unbounded (or very deep) true vacuum. We show compelling evidence that an AdS bubble of vanishing total energy, embedded in asymptotically flat spacetime, generically undergoes […]

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Avijit Shee, Zhen Huang, Martin Head-Gordon, K. Birgitta Whaley, | Summary: We have developed a new time propagation method, time-dependent adaptive sampling configuration interaction (TD-ASCI), to describe the dynamics of a strongly correlated system. We employ the short iterative Lanczos (SIL) method as the time-integrator, which provides […]
