Two-Carrier Model-Fitting of Hall Effect in Semiconductors with Dual-Band Occupation: A Case Study in GaN Two-Dimensional Hole Gas

Posted by dbos December 5, 2024Cornell

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 […]

JWST-TST DREAMS: A Precise Water Abundance for Hot Jupiter WASP-17b from the NIRISS SOSS Transmission Spectrum

Posted by dbos December 4, 2024MIT

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 […]

Weakness of X-rays and Variability in High-redshift AGNs with Super-Eddington Accretion

Posted by dbos December 4, 2024January 6, 2025Peking

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 […]

Gauge-invariant projector calculus for quantum state geometry and applications to observables in crystals

Posted by dbos December 4, 2024Berkeley

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 […]

A solvable model for strongly interacting nonequilibrium excitons

Posted by dbos December 4, 2024January 6, 2025UCSB

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 […]

Translatome analysis reveals cellular network in DLK-dependent hippocampal glutamatergic neuron degeneration

Posted by dbos December 4, 2024January 6, 2025UCSD / Salk

Kavli Affiliate: Yishi Jin | Authors: Erin M Ritchie, Siming Zhong, Qianyi Pu, Yunbo Li, Binhai Zheng and Yishi Jin | Summary: The conserved MAP3K12/Dual Leucine Zipper Kinase (DLK) plays versatile roles in neuronal development, axon injury and stress responses, and neurodegeneration, depending on cell-type and cellular contexts. Emerging evidence implicates abnormal DLK signaling in […]

A High Incidence of Central Star Formation Inferred from the Color Gradients of Galaxies at $z>4$

Posted by dbos December 4, 2024January 6, 2025Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Bingcheng Jin, Luis C. Ho, Wen Sun, , | Summary: We study the rest-frame ultraviolet-optical color gradients of 669 galaxies at $4<z<8$ by characterizing the wavelength dependence of their structural parameters derived from simultaneously fitting the seven-band NIRCam images acquired with the James Webb Space Telescope.

An Image Simulator of Lunar Far-Side Impact Flashes Captured from the Earth-Moon L2 Point

Posted by dbos December 4, 2024January 6, 2025Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Da Song, Hong-bo Cai, Shen Wang, Jing Wang, | Summary: Impact flashes on the moon are caused by high-speed collisions of celestial bodies with the lunar surface. The study of the impacts is critical for exploring the evolutionary history and formation of the Moon, and for quantifying […]
