研究目的
To investigate the interaction of nitrogen-vacancy centers in diamond with a strain field in a photonic crystal and demonstrate that it can lead to acoustic wave transparency due to the modified photonic reservoir near the photonic band edge.
研究成果
The research demonstrates that NV centers coupled to a photonic crystal can achieve acoustic wave transparency at one or two frequencies depending on the photonic DOS, with potential for 'slow sound' effects. This is feasible with current technology, as supported by recent experimental progress in strain field coupling and photonic crystal interactions.
研究不足
The study is theoretical and does not involve experimental validation; it relies on approximations in the models for photonic density of states and assumes specific conditions for the NV center interactions. Potential optimizations could include experimental verification and consideration of more complex photonic structures.
1：Experimental Design and Method Selection:
The study uses a theoretical model based on probability amplitudes without the Markov approximation, considering three different models for the photonic density of states near the band edge: single-band isotropic model, double-band isotropic model, and coupled-resonator optical waveguide (CROW) model.
2：Sample Selection and Data Sources:
The system involves nitrogen-vacancy centers in diamond coupled to a photonic crystal, with parameters derived from theoretical models and literature.
3：List of Experimental Equipment and Materials:
Not applicable as this is a theoretical study; no physical experiments were conducted.
4：Experimental Procedures and Operational Workflow:
The methodology involves deriving the Hamiltonian for the system, calculating the linear susceptibility for the acoustic field using Laplace transforms, and analyzing the results for different photonic DOS models.
5：Data Analysis Methods:
Analytical calculations and numerical simulations are used to plot the real and imaginary parts of the susceptibility, with parameters such as Rabi frequency, detuning, and coupling strengths varied.
