Quantum sensing with duplex qubits of silicon vacancy centers in SiC at room temperature

Autor: Tahara, Kosuke, Tamura, Shin-ichi, Toyama, Haruko, Nakane, Jotaro J., Kutsuki, Katsuhiro, Yamazaki, Yuichi, Ohshima, Takeshi

The silicon vacancy center in Silicon Carbide (SiC) provides an optically addressable qubit at room temperature in its spin-$\frac{3}{2}$ electronic state. However, optical spin initialization and readout are less efficient compared to those of spin-

Phonon Universal Transmission Fluctuations and Localization in Semiconductor Superlattices with a Controlled Degree of Order

Autor: Nishiguchi, Norihiko, Tamura, Shin-ichiro, Nori, Franco

Publikováno v: Phys. Rev. B 48 (1993) 14426-14435

We study both analytically and numerically phonon transmission fluctuations and localization in partially ordered superlattices with correlations among neighboring layers. In order to generate a sequence of layers with a varying degree of order we em

Phonon Transmission Rate, Fluctuations, and Localization in Random Semiconductor Superlattices: Green's Function Approach

Autor: Nishiguchi, Norihiko, Tamura, Shin-ichiro, Nori, Franco

Publikováno v: Phys. Rev. B 48 (1993) 2515-2528

We analytically study phonon transmission and localization in random superlattices by using a Green's function approach. We derive expressions for the average transmission rate and localization length, or Lyapunov exponent, in terms of the superlatti
