Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications

Advanced Physics Research, EarlyView.
Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...

Carrier Transport in Electrically‐Driven Photonic Crystal Membrane Lasers

Laser &Photonics Reviews, EarlyView.
A model to study carrier transport in photonic crystal lasers with a buried heterostructure active region and a lateral current injection scheme is presented. The model identifies unconventional leakage paths which explain low injection efficiencies and enhanced recombination at the p‐doping interface observed experimentally.

Analytic results of the excited electronic states at υ = 1/3 and the Laughlin-Jain microscopic wave function approaches

Condensed Matter Physics, 2019
In this work we studied the properties of a two-dimensional electronic gas subjected to a strong magnetic field and cooled at a low temperature. We reported exact analytical results of energies at the ground state. The results are for systems up to N_e =

Time-reversal symmetric hierarchy of fractional incompressible liquids

, 2011
We provide an effective description of fractional topological insulators that include the fractional quantum spin Hall effect by considering the time-reversal symmetric pendant to the topological quantum field theories that encode the Abelian fractional ...
