Abstract: Context. The original 1∕a-distribution is the only observational basis for the origin of long-period comets (LPCs) and the dynamical properties of the Oort Cloud. Although they are very subtle in the motion of these comets,… read more here.

DOI: 10.1088/1361-6382/ab6997
Abstract: The measured values of the Standard Model (SM) parameters favors a shallow metastable electroweak (EW) vacuum surrounded by a deep global AdS or a runaway Minkowski minimum. Furthermore, fine-tuning is the only explanation for the… read more here.

DOI: 10.1088/1475-7516/2025/02/057
Abstract: Cosmological first-order phase transition (FOPT) sources the stochastic gravitational wave background (SWGB) through bubble collisions, sound waves, and turbulence. So far, most studies on the fluid profile of an expanding bubble are limited to transitions… read more here.

DOI: 10.1139/cjp-2025-0065
Abstract: In this article, we study the real-time chiral phase transitions in the (1+1)-dimensional massive Schwinger model with a $\theta$-term in the presence of a minimal length. The minimal length, which induces quantum gravitational effects, is… read more here.
