Laser &Photonics Reviews, EarlyView.Introducing dynamical dephasing into the photon modes of a waveguide causes spontaneous emission to switch from conventional exponential decay to a robust power‐law behavior visible at short times. The power law arises from photon diffusion in a dynamically disordered environment, uncovering a previously unexplored, decoherence‐induced pathway to ...

Faraday–Ramsey Rotation in Ultrathin Alkali Vapor Cells as an Analogy to Atomic‐Beam Systems
Laser &Photonics Reviews, EarlyView.This work demonstrates that ultrathin rubidium vapor cells can emulate atomic‐beam behavior through geometry‐dependent velocity filtering. Employing a spatially separated pump–probe scheme and Faraday–Ramsey rotation, the study reveals coherent atomic dynamics without buffer gas or anti‐relaxation coatings. This approach offers a compact pathway toward

Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To investigate how the relaxation rates (R1, R2) and asymmetry indices (AI), derived from phase‐cycled balanced steady‐state free precession (pc‐bSSFP) data, depend on the orientation of white matter (WM) fiber tracts at different field strengths.

Decoherence in Excited Atoms by Low-Energy Scattering
Atoms, 2016 We describe a new mechanism of decoherence in excited atoms as a result of thermal particles scattering by the atomic nucleus. It is based on the idea that a single scattering will produce a sudden displacement of the nucleus, which will be perceived by ...

Strain Effects in a Directly Bonded Diamond‐on‐Insulator Substrate
physica status solidi (a), EarlyView.Strain effects in a directly bonded diamond‐on‐insulator substrate are investigated using NV‐based optically detected magnetic resonance and photoluminescence mapping. Enhanced volumetric and shear strain is observed near the bonded interface, but without significant degradation of NV optical properties.

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis
Advanced Quantum Technologies, EarlyView.By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.
