Kavli Affiliate: Michael F. Crommie | First 5 Authors: Hongyuan Li, Shaowei Li, Emma C. Regan, Danqing Wang, Wenyu Zhao | Summary: The Wigner crystal state, first predicted by Eugene Wigner in 1934, has fascinated condensed matter physicists for nearly 90 years2-14. Studies of two-dimensional (2D) electron gases first revealed signatures of the Wigner crystal […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Sai Sharan Injeti, Paolo Celli, Kaushik Bhattacharya, Chiara Daraio, | Summary: Acoustic transparency is the capability of a medium to transmit mechanical waves to adjacent media, without scattering. This characteristic can be achieved by carefully engineering the acoustic impedance of the medium — a combination of wave […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, Viraj Manwadkar, , , | Summary: We present a simple regulator-type framework designed specifically for modelling formation of dwarf galaxies. We explore sensitivity of model predictions for the stellar mass–halo mass and stellar mass–metallicity relations to different modelling choices and parameter values. Despite its simplicity, […]
Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Ana Botti, Mariano Cababie, Gustavo Cancelo | Summary: We use a science-grade Skipper Charge Coupled Device (Skipper-CCD) operating in a low-radiation background environment to develop a semi-empirical model that characterizes the origin of single-electron events in CCDs. We identify, separate, and quantify […]

Kavli Affiliate: Austin Joyce | First 5 Authors: Daniel Baumann, Wei-Ming Chen, Carlos Duaso Pueyo, Austin Joyce, Hayden Lee | Summary: Much of the structure of cosmological correlators is controlled by their singularities, which in turn are fixed in terms of flat-space scattering amplitudes. An important challenge is to interpolate between the singular limits to […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Yutaka Tsuzuki, Shin Watanabe, Shimpei Oishi, Nobuyuki Nakamura, Naoki Numadate | Summary: The methods to measure the polarization of the x-rays from highly charged heavy ions with a significantly higher accuracy than the existing technology is needed to explore relativistic and quantum electrodynamics (QED) effects including the […]
Kavli Affiliate: Tom Melia | First 5 Authors: Weiguang Cao, Franz Herzog, Tom Melia, Jasper Roosmale Nepveu, | Summary: We renormalize massless scalar effective field theories (EFTs) to higher loop orders and higher orders in the EFT expansion. To facilitate EFT calculations with the R* renormalization method, we construct suitable operator bases using Hilbert series […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Shenli Tang, John D. Silverman, Xuheng Ding, Junyao Li, Khee-Gan Lee | Summary: We report on a spectroscopic program to search for dual quasars using Subaru Hyper Suprime-Cam (HSC) images of SDSS quasars which represent an important stage during galaxy mergers. Using Subaru/FOCAS and Gemini-N/GMOS, we […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Prashant Kocherlakota, Luciano Rezzolla, Heino Falcke, Christian M. Fromm, Michael Kramer | Summary: Our understanding of strong gravity near supermassive compact objects has recently improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use here the M87* shadow size to infer constraints […]
