Advanced Science, EarlyView.This study quantifies the temperature‐dependent optical–acoustic phonon coupling factor (GOA) in supported single‐walled carbon nanotubes, revealing significant suppression at low temperatures. At high temperatures, GOA increases monotonically and is attributed to intensified anharmonic phonon interactions. This research offers key insights into phonon

Advanced Science, EarlyView.This study introduces a domain‐engineered PIN‐PMN‐PT ferroelectric crystal that enables efficient broadband second harmonic generation (SHG) without angle or temperature tuning. By engineering a “2T” domain structure, high SHG efficiency is achieved by noncollinear phase matching.

Advanced Electronic Materials, EarlyView.A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

Analytical Solutions of the Driven Time‐Dependent Jaynes–Cummings Model
Annalen der Physik, EarlyView.Following the great strides made in the last decade towards the control and tunability of physical parameters in cavity quantum electrodynamics, this study presents new solutions to the dynamics of the time‐dependent Jaynes–Cummings model with variable external classical fields acting on the two‐level system and the quantized field mode.

Annalen der Physik, EarlyView.Modulated thin films, when coupled to external fields, show Fano resonances. There is no simple analytical description of such micro‐optic schemes, therefore they are usually simulated numerically. We fill this gap of the lack of universal analytical description by introducing and exploring a simple mechanical equivalent, the oscillator chain, which ...
