Analytical theory of cat scars with discrete time crystalline dynamics in Floquet systems

Kavli Affiliate: Biao Huang | First 5 Authors: Biao Huang, , , , | Summary: We reconstruct the spectral pairing (SP) theories to enable analytical descriptions of eigenstate spatiotemporal orders in translation-invariant systems without prethermal conditions. It is shown that the strong Ising interactions and drivings alone stabilize a class of “cat scar" eigenstates with […]

Alteration of functional connectivity in the cortex and major brain networks of non-human primates following focused ultrasound exposure

Kavli Affiliate: Vincent Ferrera | Authors: Dong Liu, Fabian A Munoz Silva, Soroosh Sanatkhani, Antonios Pouliopoulos, Elisa Konofagou, Jack Grinband and Vincent P. Ferrera | Summary: Focused ultrasound (FUS) is a non-invasive neuromodulation technology that is being investigated for potential treatment of neurological and psychiatric disorders. Focused ultrasound combined with microbubbles can temporarily open the […]

Restructuring of olfactory representations in the fly brain around odor relationships in natural sources

Kavli Affiliate: Tatyana Sharpee | Authors: Jie-Yoon Yang, Thomas F O’Connell, Wei-Mien M Hsu, Matthew S Bauer, Kristina V. Dylla, Tatyana O Sharpee and Elizabeth J Hong | Summary: A core challenge of olfactory neuroscience is to understand how neural representations of odor are generated and progressively transformed across different layers of the olfactory circuit […]

Scrambling and Recovery of Quantum Information in Inhomogeneous Quenches in Two-dimensional Conformal Field Theories

Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Kanato Goto, Masahiro Nozaki, Shinsei Ryu, Kotaro Tamaoka, Mao Tian Tan | Summary: We study various quantum quench processes induced by the M"obius/sine-square deformation of the Hamiltonian in two-dimensional conformal field theories starting from the thermofield double state in the two copies of the Hilbert space. These […]

A “morphogenetic action” principle for 3D shape formation by the growth of thin sheets

Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Dillon J. Cislo, Anastasios Pavlopoulos, Boris I. Shraiman, , | Summary: How does growth encode form in developing organisms? Many different spatiotemporal growth profiles may sculpt tissues into the same target 3D shapes, but only specific growth patterns are observed in animal and plant development. In […]

Remarks on mod-2 elliptic genus

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Mayuko Yamashita, Kazuya Yonekura, , | Summary: For physicists: For supersymmetric quantum mechanics, there are cases when a mod-2 Witten index can be defined, even when a more ordinary $mathbb{Z}$-valued Witten index vanishes. Similarly, for 2d supersymmetric quantum field theories, there are cases when a […]
