Contributed Talk (20 minutes)

Cosmic string networks are expected to form during symmetry-breaking phase transitions in the early Universe via the Kibble mechanism and arise naturally in many extensions of the Standard Model. In several such scenarios, string networks can carry additional degrees of freedom, such as charges and currents, leading to so-called current-carrying or superconducting cosmic strings. These...

Contributed Talk (20 minutes)

Core-collapse supernova (CCSN) events remain one of the most compelling yet still uncovered sources of gravitational wave (GW) signals. Their detection would open a direct window into the physics unfolding deep within a collapsing stellar core. In this work, we evaluate deep-learning (DL) approaches for analyzing GW signals from rotating CCSN, addressing both the classification of these...

177. Non-Minimally Coupled Chain Inflation at High Scales

Contributed Talk (20 minutes)

Chain inflation offers an alternative to standard slow-roll dynamics, with accelerated expansion proceeding through a sequence of rapid quantum tunneling events between metastable vacua. At the high energy scales relevant for the early Universe, scalar fields are generically expected to couple non-minimally to gravity via operators like $\xi R\phi^2$, allowed by symmetry and required as...

191. Symmetry Aware Ansatz for Matrix Quantum Mechanics

Júlio Oliveira (University of Porto)

We develop a symmetry-aware neural quantum state for the $SU(2)$ minimal BMN model. The ansatz enforces gauge and $SO(2)$ invariance through a trace-operator basis and incorporates a WKB-inspired asymptotic tail. This construction enables us to probe the model deep into the strong-coupling regime.
