Exploring Many-Body Quantum Geometry Beyond the Quantum Metric with Correlation Functions: A Time-Dependent Perspective

This paper establishes a general time-dependent framework for many-body quantum geometry by treating external fields as coordinates on the space of density matrices, utilizing the Bures distance to derive a generalized metric and connection that unify linear response theory and reveal how higher-order correlation functions probe nonlinear geometric structures.

The analytically tractable zoo of similarity-induced exceptional structures

This paper maps out the analytically tractable landscape of multifold exceptional structures in three and four dimensions under generalized similarities, revealing that spectral symmetries induced by these similarities can reduce the dimensionality of exceptional point manifolds beyond naive constraint counting, thereby unifying diverse physical scenarios from optics to open quantum systems.

Classification of topological insulators and superconductors with multiple order-two point group symmetries

This paper presents a general method for computing the classification groups of topological insulators and superconductors under arbitrary Z2×n\mathbb{Z}_2^{\times n} point group symmetries, demonstrating that these classifications are fully determined by the number of momentum and real-space variables flipped by individual and paired symmetry generators.

Emergent spatiotemporal order and nonreciprocity in driven-dissipative nonlinear magnetic systems

This paper demonstrates that driven-dissipative nonlinear magnetic multilayers can spontaneously form a chiral spin superfluid condensate that acts as a nonreciprocal diode and, through spatial drive modulation, generates sonic horizons to produce Hawking-like magnon emission, thereby establishing a tabletop platform for studying non-Hermitian universality and analogue gravity.

Exact time-evolving resonant states for open double quantum-dot systems with spin degrees of freedom

This paper presents an exact analytical solution for time-evolving resonant states in an open double quantum-dot system with spin and Coulomb interactions, deriving a non-Hermitian effective Hamiltonian that identifies four types of two-body resonant states and enables the precise calculation of survival and transition probabilities for localized electrons.
