EDEN: Exploring Disks Embedded in N-body simulations of Milky-Way-mass halos from Symphony

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Yunchong Wang, Philip Mansfield, Ethan O. Nadler, Elise Darragh-Ford, Risa H. Wechsler | Summary: We investigate the impact of galactic disks on the tidal stripping of cold dark matter subhalos within Milky Way (MW)-mass halos ($M_{rm vir}sim 10^{12}mathrm{M_{odot}}$) using a new simulation suite, EDEN. By re-simulating […]

Phonon screening of excitons in atomically thin semiconductors

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Woncheol Lee, Antonios M. Alvertis, Zhenglu Li, Steven G. Louie, Marina R. Filip | Summary: Atomically thin semiconductors, encompassing both 2D materials and quantum wells, exhibit a pronounced enhancement of excitonic effects due to geometric confinement. Consequently, these materials have become foundational platforms for the exploration […]

Diverse dark matter haloes in Two-field Fuzzy Dark Matter

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Hoang Nhan Luu, Philip Mocz, Mark Vogelsberger, Alvaro Pozo, Tom Broadhurst | Summary: Fuzzy dark matter (FDM) is a compelling candidate for dark matter, offering a natural explanation for the structure of diffuse low-mass haloes. However, the canonical FDM model with a mass of $10^{-22}~{rm eV}$ encounters […]

Tensionless AdS$_3$/CFT$_2$ and Single Trace $Toverline{T}$

Kavli Affiliate: Savdeep Sethi | First 5 Authors: Andrea Dei, Bob Knighton, Kiarash Naderi, Savdeep Sethi, | Summary: One of the few cases of AdS/CFT where both sides of the duality are under good control relates tensionless $k=1$ strings on AdS$_3$ to a two-dimensional symmetric product CFT. Building on prior observations, we propose an exact […]

Intermittent Semi-working Mask: A New Masking Paradigm for LLMs

Kavli Affiliate: Feng Wang | First 5 Authors: Mingcong Lu, Jiangcai Zhu, Wang Hao, Zheng Li, Shusheng Zhang | Summary: Multi-turn dialogues are a key interaction method between humans and Large Language Models (LLMs), as conversations extend over multiple rounds, keeping LLMs’ high generation quality and low latency is a challenge. Mainstream LLMs can be […]

Discovery of Dynamical Heterogeneity in a Supercooled Magnetic Monopole Fluid

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Jahnatta Dasini, Chaia Carroll, Chun-Chih Hsu, Hiroto Takahashi, Jack Murphy | Summary: Dynamical heterogeneity in which transitory local fluctuations occur in the conformation and dynamics of constituent particles, is essential for evolution of supercooled liquids into the glass state. Yet its microscopic spatiotemporal phenomenology has […]
