On a class of selection rules without group actions in field theory and string theory

Posted by dbos Tokyo

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Justin Kaidi, Yuji Tachikawa, Hao Y. Zhang, , | Summary: We discuss a class of selection rules which i) do not come from group actions on fields, ii) are exact at tree level in perturbation theory, iii) are increasingly violated as the loop order is raised, and […]

Incorporation of a cost of deliberation time in perceptual decision making

Posted by dbos Columbia

Kavli Affiliate: Michael Shadlen | Authors: Shinichiro Kira, Ariel Zylberberg and Michael N Shadlen | Summary: Abstract Many decisions benefit from the accumulation of evidence obtained sequentially over time. In such circumstances, the decision maker must balance speed against accuracy, and the nature of this tradeoff mediates competing desiderata and costs, especially those associated with […]

Chirality-induced Phonon-Spin Conversion at an Interface

Posted by dbos UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Takumi Funato, Mamoru Matsuo, Takeo Kato, , | Summary: We consider spin injection driven by nonequilibrium chiral phonons from a chiral insulator into an adjacent metal. Phonon-spin conversion arises from the coupling of the electron spin with the microrotation associated with chiral phonons. We derive a microscopic […]

Exciton-phonon coupling induces new pathway for ultrafast intralayer-to-interlayer exciton transition and interlayer charge transfer in WS2-MoS2 heterostructure: a first-principles study

Posted by dbos Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Yang-hao Chan, Mit H. Naik, Jonah B. Haber, Jeffrey B. Neaton, Steven G. Louie | Summary: Despite the weak, van-der-Waals interlayer coupling, photoinduced charge transfer vertically across atomically thin interfaces can occur within surprisingly fast, sub-50fs timescales. Early theoretical understanding of the charge transfer is based […]

SWEA: Updating Factual Knowledge in Large Language Models via Subject Word Embedding Altering

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Xiaopeng Li, Shasha Li, Shezheng Song, Huijun Liu, Bin Ji | Summary: The general capabilities of large language models (LLMs) make them the infrastructure for various AI applications, but updating their inner knowledge requires significant resources. Recent model editing is a promising technique for efficiently updating a […]

SWEA: Changing Factual Knowledge in Large Language Models via Subject Word Embedding Altering

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Xiaopeng Li, Shasha Li, Bin Ji, Shezheng Song, Xi Wang | Summary: Model editing has recently gained widespread attention. Current model editing methods primarily involve modifying model parameters or adding additional modules to the existing model. However, the former causes irreversible damage to LLMs, while the latter […]
