BPS Fivebrane Stars II: Fluctuations

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Yoav Zigdon, , , | Summary: We investigate quantum fluctuations of metric components in coherent 1/2-BPS bound states of $n_1$ fundamental strings and $n_5$ NS5-branes. The leading order contribution in an expansion in $1/(n_1n_5)$ is calculated via a combination of analytical and numerical […]

BPS Fivebrane Stars I: Expectation Values of Observables

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, Yoav Zigdon, , , | Summary: We study ensembles of 1/2-BPS bound states of fundamental strings and NS-fivebranes (NS5-F1 states) in the AdS decoupling limit. We revisit a solution corresponding to an ensemble average of these bound states, and find that the appropriate […]

Josephson Diode Effect in Topological Superconductor

Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Linghao Huang, Jing Wang, , | Summary: We investigate the Josephson diode effect in topological Josephson junctions. We find that while a Josephson junction in the topological phase may exhibit higher diode efficiency compared to that in the trivial phase, this behavior is not universal. […]

Josephson Diode Effect in Topological Superconductor

Kavli Affiliate: Jing Wang | First 5 Authors: Zhaochen Liu, Linghao Huang, Jing Wang, , | Summary: We investigate the Josephson diode effect (JDE) in topological Josephson junctions. By both analytic and numerical calculations, we find that while a Josephson junction in the topological phase may exhibit higher diode efficiency compared to that in the […]

Alignment is not sufficient to prevent large language models from generating harmful information: A psychoanalytic perspective

Kavli Affiliate: Jia Liu | First 5 Authors: Zi Yin, Wei Ding, Jia Liu, , | Summary: Large Language Models (LLMs) are central to a multitude of applications but struggle with significant risks, notably in generating harmful content and biases. Drawing an analogy to the human psyche’s conflict between evolutionary survival instincts and societal norm […]

Charged vacancy in graphene: interplay between Landau levels and atomic collapse resonances

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Wen-Sheng Zhao, Yue Hu, R. N. Costa Filho, Francois M. Peeters | Summary: The interplay between a magnetic field and the Coulomb potential from a charged vacancy on the electron states in graphene is investigated within the tight-binding model. The Coulomb potential removes locally Landau […]
