Behavioural Approach to Distributed Control of Interconnected Systems

Kavli Affiliate: Biao Huang | First 5 Authors: Yitao Yan, Jie Bao, Biao Huang, , | Summary: This paper formulates a framework for the analysis and distributed control of interconnected systems from the behavioural perspective. The discussions are carried out from the viewpoint of set theory and the results are completely representation-free. The core of […]

On the exponentially small corrections to ${cal N} = 2$ superconformal correlators at large R-charge

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, , , , | Summary: In this note we consider Coulomb-branch chiral primary correlation functions in ${cal N} = 2$ superconformal QCD with gauge group $SU(2)$, in the limit of large R-charge ${cal J} = 2n$ for the chiral primary operators $[{cal O}(x)]^ n$ with […]

Spin-Phonon Interaction in Yttrium Iron Garnet

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Kevin S. Olsson, Jeongheon Choe, Martin Rodriguez-Vega, Guru Khalsa, Nicole A. Benedek | Summary: Spin-phonon interaction is an important channel for spin and energy relaxation in magnetic insulators. Understanding this interaction is critical for developing magnetic insulator-based spintronic devices. Quantifying this interaction in yttrium iron garnet […]

To H0 or not to H0?

Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: This paper investigates whether changes to late time physics can resolve the `Hubble tension’. It is argued that many of the claims in the literature favouring such solutions are caused by a misunderstanding of how distance ladder measurements actually work […]

Non-universal current flow near the metal-insulator transition in an oxide interface

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Eylon Persky, Naor Vardi, Ana Mafalda R. V. L. Monteiro, Thierry C. van Thiel, Hyeok Yoon | Summary: In systems near phase transitions, macroscopic properties often follow algebraic scaling laws, determined by the dimensionality and the underlying symmetries of the system. The emergence of such universal […]
