Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, Will Barker, , | Summary: A variational principle for gauge theories of gravity is presented, which maintains manifest covariance under the symmetries to which the action is invariant, throughout the calculation of the equations of motion and conservation laws. This is performed by […]
Kavli Affiliate: Ke Wang | First 5 Authors: Fengwei Xu, Ke Wang, Yuxin He, Jingwen Wu, Lei Zhu | Summary: Gas infall motions play a crucial role in high-mass star formation and are characterized by observable signatures in the form of blue-shifted asymmetric spectral line profiles ("blue profiles"). However, the connection between blue profiles and […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Yahong Chai, Yuhan Liang, Cancheng Xiao, Yue Wang, Bo Li | Summary: Magnons, bosonic quasiparticles carrying angular momentum, can flow through insulators for information transmission with minimal power dissipation. However, it remains challenging to develop a magnon-based logic due to the lack of efficient electrical manipulation […]
Kavli Affiliate: Mark Ellisman | Authors: Guillaume A Castillon, Sebastien Phan, Junru Hu, Daniela Boassa, Stephen R Adams and Mark H Ellisman | Summary: The binding and interaction of proteins with nucleic acids such as DNA and RNA constitutes a fundamental biochemical and biophysical process in all living organisms. Identifying and visualizing such temporal interactions […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Angela V. Olinto, , , , | Summary: The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) was designed as a NASA Astrophysics probe-class mission to identify the sources of ultrahigh energy cosmic rays (UHECRs) and observe cosmic neutrinos from extremely energetic transient sources. POEMMA consists of two […]
Kavli Affiliate: V. S. Ramachandran | Authors: B.R. Ansil, Ashwin Viswanathan, Vivek Ramachandran, H.M. Yeshwanth, Avirup Sanyal and Uma Ramakrishnan | Summary: Our understanding of pathogen spillover is largely based on viral systems associated with bats. Bacterial infections of zoonotic origin also pose a significant public health burden, many of which are associated with small […]
Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Jessica H. Sun, Abigail Plummer, Grace H. Zhang, David R. Nelson, Vinothan N. Manoharan | Summary: Conical surfaces pose an interesting challenge to crystal growth: a crystal growing on a cone can wrap around and meet itself at different radii. We use a disk-packing algorithm to […]
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 […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jun-ichi Sakamoto, Masahito Yamazaki, , | Summary: We elucidate the relationship between 2d integrable field theories and 2d integrable lattice models, in the framework of the 4d Chern-Simons theory. The 2d integrable field theory is realized by coupling the 4d theory to multiple 2d surface […]
