| Abstract | Entanglement asymmetry provides a quantitative measure of symmetry breaking in many-body quantum states. Focusing on inhomogeneous U(1) charges, such as dipole and multipole moments, we show that the typical asymmetry is bounded by a universal fraction of its maximal value. Multipole charges naturally arise in systems with Hilbert-space fragmentation, where the dynamics splits into exponentially many disconnected sectors. Using the commutant algebra formalism, we generalize entanglement asymmetry to account for fragmentation. While the asymmetry grows logarithmically for conventional symmetries, it can scale extensively in fragmented systems and distinguish classical from quantum fragmentation. We derive general upper bounds for the asymmetry and identify states that saturate them. To study the typical behavior of the asymmetry, we consider the ensemble of random matrix product states. By identifying the bond dimension with an effective time parameter, we qualitatively reproduce recent results on asymmetry dynamics in random quantum circuits, suggesting a universal behavior for the asymmetry of U(1) charges in local ergodic systems. |

| Abstract | Underwater environments prominently feature a dimension of light invisible to our own eyes, polarization. Cephalopods (octopus, cuttlefish and squid) detect polarization with both high sensitivity and resolution, skillfully utilizing it for complex behaviors such as hunting and communication. However, the neural mechanisms for encoding patterns of light polarization remain poorly understood. Using the bigfin reef squid (Sepioteuthis lessoniana), we developed a new head- fixation method to perform two photon calcium imaging in awake squid, providing the first in vivo recordings of the cephalopod visual system at cellular resolution. In the optic lobe cortex, the brain region receiving input from retinal photoreceptors, we identified distinct neuron classes defined by spatiotemporal tuning and light intensity vs polarization specificity, including (i) integrators of polarized photoreceptor inputs, (ii) neurons selective for a single polarization orientation, and (iii) neurons that subtract orthogonal polarization signals—together suggesting notable parallels with color coding in the vertebrate retina. Neuropixels recordings from downstream visual brain regions revealed evidence for hierarchical processing: receptive fields expanded with depth, and intensity and polarization signals were integrated with progressively greater complexity. Collectively, our study provides new insights into the neural computations underlying cephalopods’ specialized underwater vision and the convergent evolution of visual systems. |

| Abstract | Coupling molecules to confined electromagnetic fields inside optical microcavities gives rise to hybrid light–matter states known as polaritons, opening new avenues to control chemical phenomena. Recent experiments suggest that strong light–matter coupling can alter photochemical pathways, modify ground-state reactivity, and enhance energy and charge transport—yet the underlying mechanisms remain poorly understood. Here, I will present theoretical advances developed in my group that enable accurate ab initio simulations of molecular response properties and dynamics under strong coupling to quantized radiation fields. These methods provide new insights into how cavity photons reshape molecular dynamical behavior. I will also introduce a recently proposed mechanism that explains changes in ground-state chemical reactivity under vibrational strong coupling. Together, these results offer new theoretical tools and conceptual mechanistic pictures for understanding and predicting polaritonic effects in chemistry, and highlight emerging opportunities for controlling chemical processes with light. |
