Strong-field regime within effective field theory

Sebastián Franchino-Viñas, Jérémie Quevillon, Diego Saviot·Dec 8, 2025

Building upon the Covariant Derivative Expansion, we develop a method to compute effective actions that is able to capture non-perturbative effects induced by strong background fields. We demonstrate the method in scalar QED, by deriving the full sec...

Robustness of flat band superconductivity against disorder in a two-dimensional Lieb lattice model

Georges Bouzerar, Maxime Thumin·Dec 8, 2025

Recently, the possibility of high-temperature superconductivity (SC) in flat-band (FB) systems has been the focus of a great deal of activity. This study reveals that unlike conventional intra-band SC for which disorder has a dramatic impact, that as...

Anomalous Wave-Packet Dynamics in One-Dimensional Non-Hermitian Lattices

Yanyan He, Tomoki Ozawa·Dec 8, 2025

Non-Hermitian (NH) systems have attracted great attention due to their exotic phenomena beyond Hermitian domains. Here we study the wave-packet dynamics in general one-dimensional NH lattices and uncover several unexpected phenomena. The group veloci...

From Quantum Chaos to Classical Chaos via Gain-Induced Measurement Dynamics in a Photon Gas

Violetta Sharoglazova, Marius Puplauskis, Lotte Hof +1 more·Dec 7, 2025

How classical chaos emerges from quantum mechanics remains a central open question, as the unitary evolution of isolated quantum systems forbids exponential sensitivity to initial conditions. A key insight is that this quantum-classical link is provi...

Multiple re-entrant topological windows induced by generalized Bernoulli disorder

Ruijiang Ji, Yunbo Zhang, Shu Chen +1 more·Dec 7, 2025

We investigate re-entrant topological behavior in a one-dimensional Su-Schrieffer-Heeger model with generalized Bernoulli-type disorder in the intradimer hopping amplitudes. We show that varying the values and probabilities of the disorder distributi...

Geometry-Induced Vacuum Polarization and Mode Shifts in Maxwell-Klein-Gordon Theory

Li Wang, Jun Wang, Yong-Long Wang·Dec 7, 2025

Geometric confinement is known to modify single-particle dynamics through effective potentials, yet its imprint on the interacting quantum vacuum remains largely unexplored. In this work, we investigate the Maxwell--Klein--Gordon system constrained t...

Exploring the topology induced by non-Markovian Liouvillian exceptional points

Hao-Long Zhang, Yan Wang, Wen Ning +6 more·Dec 6, 2025

Non-Hermitian (NH) systems can display exotic topological phenomena without Hermitian counterparts, enabled by exceptional points (EPs). So far, investigations of NH topology have been restricted to EPs of the NH Hamiltonian, which governs the system...

Entanglement is protected by acceleration-induced transparency in thermal field

Yongjie Pan, Baocheng Zhang, Qingyu Cai·Dec 5, 2025

The acceleration-induced transparency (AIT) effect has been suggested recently to amply the transition probability of the two-level detctor and offers a potential avenue for the experimental detection of the Unruh effect. In this paper, we explore th...
