Kavli Affiliate: Feng Wang | First 5 Authors: Yingbin Lin, Feng Wang, Xiao Zhang, Guojun Han, Vincent K. N. Lau | Summary: This paper considers a hybrid reconfigurable intelligent surface (RIS) assisted integrated sensing and communication (ISAC) system, where each RIS element can flexibly switch between the active and passive modes. Subject to the signal-to-interference-plus-noise […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Bingchen Li, Xin Li, Yiting Lu, Zhibo Chen, | Summary: We present the first loss agent, dubbed LossAgent, for low-level image processing tasks, e.g., image super-resolution and restoration, intending to achieve any customized optimization objectives of low-level image processing in different practical applications. Notably, not all […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Yang-hao Chan, Jonah B. Haber, Mit H. Naik, Steven G. Louie, Jeffrey B. Neaton | Summary: Understanding exciton thermalization is critical for optimizing optoelectronic and photocatalytic processes in many materials. However, it is hard to access the dynamics of such processes experimentally, especially on systems such […]
Kavli Affiliate: Ruobing Dong | First 5 Authors: Yuhito Shibaike, Jun Hashimoto, Ruobing Dong, Christoph Mordasini, Misato Fukagawa | Summary: Gas accreting planets embedded in protoplanetary disks are expected to show dust thermal emission from their circumplanetary disks (CPDs). However, a recently reported gas accreting planet candidate, AB Aurigae b, has not been detected in […]
Kavli Affiliate: Grace Xing | First 5 Authors: Joseph E. Dill, Chuan F. C. Chang, Debdeep Jena, Huili Grace Xing, | Summary: We develop a two-carrier Hall effect model fitting algorithm to analyze temperature-dependent magnetotransport measurements of a high-density ($sim4times10^{13}$ cm$^2$/Vs) polarization-induced two-dimensional hole gas (2DHG) in a GaN/AlN heterostructure. Previous transport studies in GaN […]
Kavli Affiliate: Sara Seager | First 5 Authors: Dana R. Louie, Elijah Mullens, Lili Alderson, Ana Glidden, Nikole K. Lewis | Summary: Water has proven to be ubiquitously detected in near-infrared (NIR) transmission spectroscopy observations of hot Jupiter atmospheres, including WASP-17b. However, previous analyses of WASP-17b’s atmosphere based upon Hubble Space Telescope (HST) and Spitzer […]

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Shigeo Kimura, Hirofumi Noda, , | Summary: The James Webb Space Telescope (JWST) observations enable the exploration of active galactic nuclei (AGNs) with broad-line emission in the early universe. Despite their clear radiative and morphological signatures of AGNs in rest-frame optical bands, complementary evidence of […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Johannes Mitscherling, Alexander Avdoshkin, Joel E. Moore, , | Summary: The importance of simple geometrical invariants, such as the Berry curvature and quantum metric, constructed from the Bloch states of a crystal has become well-established over four decades of research. More complex aspects of geometry emerge […]
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 […]
