Time‐Stretched Interferometric LiDAR with Dispersive Wavenumber‐to‐Time Range Encoding

Laser &Photonics Reviews, EarlyView.
We present a time‐stretched interferometric LiDAR that directly encodes distance into time‐domain interference signals. Operating at 5 MHz with only millimeter‐level coherence length, the system measures up to 12 m with centimeter precision and resolution, achieving high‐speed 3D imaging and dynamic target detection without FFT processing or long ...

Breaking the Exponential: Decoherence‐Driven Power‐Law Spontaneous Emission in Waveguide Quantum Electrodynamics

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 ...

Alloy Solutions for Ammonia Cracking: A Review

Materials and Corrosion, EarlyView.
This work provides a literature overview of the nitriding and degradation of structural materials under ammonia cracking conditions and explains the known mechanisms and the gaps, where research is required. ABSTRACT Hydrogen is a key factor in energy storage and transportation, which will inevitably lead to a substantial increase in demand.

Dual Variational Problems and Action Principles for Chen–Lee and Hopf–Langford Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We describe the construction of dual variational principles and action functionals for nonlinear dynamical systems using a methodology based on the dual Lagrange multiplier formalism and a convex optimization approach, to derive families of dual actions that correspond to the given nonlinear ordinary differential system.
