Epitaxial lattice-matched Al$_{0.89}$Sc$_{0.11}$N/GaN distributed Bragg reflectors

Posted by dbos Cornell

Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Thai-Son Nguyen, Joseph Casamento, Huili Grace Xing, Debdeep Jena | Summary: We demonstrate epitaxial lattice-matched Al$_{0.89}$Sc$_{0.11}$N/GaN ten and twenty period distributed Bragg reflectors (DBRs) grown on c-plane bulk n-type GaN substrates by plasma-enhanced molecular beam epitaxy (PA-MBE). Resulting from a rapid increase of in-plane […]

Simulating ionization feedback from young massive stars: impact of numerical resolution

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Yunwei Deng, Hui Li, Rahul Kannan, Aaron Smith, Mark Vogelsberger | Summary: Modelling galaxy formation in hydrodynamic simulations has increasingly adopted various radiative transfer methods to account for photoionization feedback from young massive stars. However, the evolution of HII regions around stars begins in dense star-forming clouds […]

Kitaev chain in an alternating quantum dot-Andreev bound state array

Posted by dbos Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Sebastian Miles, David van Driel, Michael Wimmer, Chun-Xiao Liu, | Summary: We propose to implement a Kitaev chain based on an array of alternating normal and superconductor hybrid quantum dots embedded in semiconductors. In particular, the orbitals in the dot and the Andreev bound states in the […]

Identifiability Matters: Revealing the Hidden Recoverable Condition in Unbiased Learning to Rank

Posted by dbos Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Mouxiang Chen, Chenghao Liu, Zemin Liu, Zhuo Li, Jianling Sun | Summary: Unbiased Learning to Rank (ULTR) aims to train unbiased ranking models from biased click logs, by explicitly modeling a generation process for user behavior and fitting click data based on examination hypothesis. Previous research found […]

TOI-199 b: A well-characterized 100-day transiting warm giant planet with TTVs seen from Antarctica

Posted by dbos MIT

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Melissa J. Hobson, Trifon Trifonov, Thomas Henning, Andrés Jordán, Felipe Rojas | Summary: We present the spectroscopic confirmation and precise mass measurement of the warm giant planet TOI-199 b. This planet was first identified in TESS photometry and confirmed using ground-based photometry from ASTEP in Antarctica […]

Simplicity of AdS Super Yang-Mills at One Loop

Posted by dbos UCAS

Kavli Affiliate: Xinan Zhou | First 5 Authors: Zhongjie Huang, Bo Wang, Ellis Ye Yuan, Xinan Zhou, | Summary: We perform a systematic bootstrap analysis of four-point one-loop Mellin amplitudes for super gluons in $mathrm{AdS}_5timesmathrm{S}^3$ with arbitrary Kaluza-Klein weights. The analysis produces the general expressions for these amplitudes at extremalities two and three, as well […]
