The Kibble-Zurek mechanism (KZM) predicts that the average number of topological defects generated upon crossing a continuous or quantum phase transition obeys a universal scaling law with the quench time. Fluctuations in the defect number near equilibrium are approximately of Gaussian form, in agreement with the central limit theorem. Using large deviations theory, we characterize the universality of fluctuations beyond the KZM and report the exact form of the rate function in the transverse-field quantum Ising model.

- Pancreatic cystic lesions, often discovered incidentally, vary in severity regarding their risk for cancer, with intraductal papillary mucinous neoplasms (IPMN) being particularly concerning as they can range from benign to malignant.
- The detection and management of IPMN have been enhanced by the use of imaging techniques like CT and MRI, with MRI being the primary tool for diagnosis and ongoing monitoring, especially for branch-duct IPMN, which are the most common and challenging to manage.
- This review focuses on showcasing the MRI characteristics of IPMN, discussing risk assessment frameworks, and addressing both common and rare imaging changes in branch-duct IPMN, while also debating current management approaches.
We study the nonequilibrium evolution of coexisting ferromagnetic domains in the two-dimensional quantum Ising model-a setup relevant in several contexts, from quantum nucleation dynamics and false-vacuum decay scenarios to recent experiments with Rydberg-atom arrays. We demonstrate that the quantum-fluctuating interface delimiting a large bubble can be studied as an effective one-dimensional system through a "holographic" mapping. For the considered model, the emergent interface excitations map to an integrable chain of fermionic particles.
