Kavli Affiliate: Joel E. Moore | First 5 Authors: Siddhant Mal, Elizabeth J. Dresselhaus, Joel E. Moore, , | Summary: Recent experiments on amorphous materials have established the existence of surface states similar to those of crystalline three-dimensional topological insulators (TIs). Amorphous topological insulators are also independently of interest for thermo-electric and other properties. To […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Senyu Li, Ning Shi, Bradley Hauer, Zijun Wu | Summary: Recent developments in multimodal methodologies have marked the beginning of an exciting era for models adept at processing diverse data types, encompassing text, audio, and visual content. Models like GPT-4V, which merge computer vision with […]

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: Feng Wang | First 5 Authors: Aditya Bahulikar, Feng Wang, Mustafa Cenk Gursoy, Rodrick Kuate Defo, | Summary: We present a structure-adaptive topology optimization framework for engineering photonic band gaps with TM-polarized sources based on computation of the photonic density of states with a uniform source substituting for the standard Dirac delta function […]

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: 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 […]
