Collapse versus Disruption: The Fate of Compact Stellar Systems in Ultralight Dark Matter Halos

This study uses numerical simulations to demonstrate that the fate of compact stellar systems in ultralight dark matter halos is determined by a competition between internal relaxation-driven core collapse and ULDM-induced heating, leading to either survival or disruption depending on the system's size and establishing a new evolutionary phase diagram for robust dark matter constraints.

Stationary perturbation theory without sums over intermediate states: Supersymmetric Expansion Algorithm

This paper demonstrates that the supersymmetric expansion algorithm can efficiently derive Rayleigh-Schrödinger perturbation theory results for energy and eigenstate corrections without summing over intermediate states, instead expressing them as integrals weighted by the probability densities of edge states.

Spatial Wilson Loops and Energy Loss for Heavy Quarks in Magnetized HQCD Model

Using a holographic heavy quark model, this paper investigates how external magnetic fields and spatial anisotropy affect the effective potential, string tension, and energy loss of heavy quarks in hot dense QGP, revealing magnetic catalysis in phase transitions and anisotropy-dependent deviations from the standard $T^2$ scaling of string tension.

Properties of the Top Quark

This review summarizes the most recent results from the D0, CDF, ATLAS, and CMS experiments at the Tevatron and LHC colliders regarding the properties of the top quark, the heaviest known elementary particle and a key probe for new physics.
