Coherence, Transport, and Chaos in 1D Bose–Hubbard Model: Disorder vs. Stark Potential

open access: yesFortschritte der Physik, Volume 73, Issue 11, November 2025.
Quantum coherence and criticality in finite Bose–Hubbard chains are investigated using exact diagonalization. Thermal fluctuations, Stark potential, and disorder reshape coherence, visibility, and superfluid response. Finite‐size systems show signatures of quantum criticality, with disorder suppressing global superfluidity but preserving local ...

Dark Excitonic State Preparation in a Symmetry‐Protected Open Quantum Battery

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 11, November 2025.
An optical charging protocol is presented for an excitonic quantum battery that prepares the system in a symmetry‐protected dark excited state. Using a continuous‐wave laser followed by controlled relaxation, the system stores energy in a state resilient to environmental losses. Abstract Previous work (J. Phys. Chem.

Broken Structural Symmetry in Terahertz Detectors: Physical Mechanisms, Device Design, and Recent Advances

open access: yesSmall Structures, Volume 6, Issue 11, November 2025.
Breaking the structural symmetry of devices is a crucial design strategy that endows terahertz (THz) detectors with novel operating mechanisms and unique characteristics. This study provides an in‐depth discussion on symmetry‐breaking‐induced phenomena, novel asymmetric structures, and dominant detection mechanisms.
