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...

Scintillation is the phenomenon of luminescence in solids, liquids or gases, originating at the propagation of the ionizing radiation through them. It has long found applications in radiation detection and dosimetry. Currently, most commercial scintillators are inorganic compounds. They exhibit excellent scintillation properties, but suffer from harsh fabrication conditions, high costs and...

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...

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...

Rare-earth orthoferrites, such as NdFeO3, exhibit intricate magnetic and structural transitions, making them compelling for
spintronics and optoelectronic applications. NdFeO 3 undergoes a spin-reorientation transition (SRT) between 170 K and 100
K, accompanied by symmetry changes from orthorhombic (Pbnm) to monoclinic (P2 ₁/c). This work explores these
phenomena and their... -

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.

The electromagnetic duality is a symmetry of Maxwell’s equations in vacuum that can be used as a method to generate dyonic or magnetic solutions from the purely charged case. Since this symmetry does not make any assumptions regarding the underlying geometry, it also applies to dynamical spacetimes. Here, we show that the emitted electromagnetic radiation differs between solutions in the same...

Weyl nodal loop semimetals are topological semimetals where the valence and conduction bands linearly touch along one dimensional loops in momentum space. A manifestation of their non-trivial topology is the presence of zero energy surface states, induced by chiral symmetry, on surfaces parallel to the loop plane.

The nonequilibrium generation of orbital magnetization by applied electric fields is a central problem in the emerging field of orbitronics [1,2].

The LUX-ZEPLIN (LZ) experiment recently reported a nuclear recoil candidate at $E_R \simeq 248 $ keV. Inelastic dark matter (DM) is among the best-motivated explanations of this signal, since it suppresses the low-energy recoils that elastic scattering would predict. However, in thermal freeze-out the relic density fixes the DM–nucleon cross section for a given mass. In this talk, based on...
