Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Yuya Kusuki, Sara Murciano, Hirosi Ooguri, Sridip Pal, | Summary: A state in a quantum system with a given global symmetry, $G$, can be sensitive to the presence of boundaries, which may either preserve or break this symmetry. In this work, we investigate how conformal invariant boundary […]
Kavli Affiliate: Gabriel Silva | Authors: Jeziel D Damasceno, Gabriel LA Silva, Catarina A Marques, Marija Krasilnikova, Craig Lapsley, Dario Beraldi and Richard McCulloch | Summary: Understanding genome duplication requires characterisation of the locations where DNA replication initiates, termed origins. Genome-wide mapping of DNA replication origins has mainly been derived from population-based techniques, with only […]
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: Saul Rappaport | First 5 Authors: Jim Fuller, Saul Rappaport, Rahul Jayaraman, Don Kurtz, Gerald Handler | Summary: Stars in close binaries are tidally distorted, and this has a strong effect on their pulsation modes. We compute the mode frequencies and geometries of tidally distorted stars using perturbation theory, accounting for the effects […]
Kavli Affiliate: Jie Shan | First 5 Authors: Yi Jiang, Urko Petralanda, Grigorii Skorupskii, Qiaoling Xu, Hanqi Pi | Summary: The study of twisted two-dimensional (2D) materials, where twisting layers create moir’e superlattices, has opened new opportunities for investigating topological phases and strongly correlated physics. While systems such as twisted bilayer graphene (TBG) and twisted […]
Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Bin Zheng, Shigeyuki Komura, David Andelman, Rudolf Podgornik, | Summary: Onsager’s variational principle is generalized to address the diffusive dynamics of an electrolyte solution composed of charge-regulated macro-ions and counterions. The free energy entering the Rayleighian corresponds to the Poisson-Boltzmann theory augmented by the charge-regulation mechanism. The […]
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: Yuji Tachikawa | First 5 Authors: Shota Saito, Yuji Tachikawa, , , | Summary: We study if and when mod-2 anomalies can be canceled by the Green-Schwarz mechanism with the introduction of an antisymmetric tensor field $B_{munu}$. As explicit examples, we examine $SU(2)$ and more general $Sp(n)$ gauge theories in four and eight […]
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 […]
