Entanglement Between Microwave Photons Through a Spin Ensemble.
The nuclear spin polarization. We will present here our recent theoretical results on relaxation and decoherence processes of nuclear spin qubits in low-dimensional semiconductors and nanostructures [3]-[6] and on possibility of optical and microwave manipulation of nuclear spins in these systems. As sketched in Fig. 1, our proposed system is consisting of a transmission line resonator TLR of frequency r and decay rate r and a microwave cavity of frequency w and decay rate w which are coupled together through an spin ensemble of yttrium iron garnet YIG molecules.The resonance frequency of the YIG is determined by an applied external bias magnetic field H via s.

Effects of Microwave Gating on Nuclear Spin Echoes in Dynamic.
For the microwave frequency of 9388.4 MHz, the predicted resonance occurs at a magnetic field of about = / = 0.3350 T = 3350 G. Because of electron-nuclear mass differences, the magnetic moment of an electron is substantially larger than the corresponding quantity for any nucleus, so that a much higher electromagnetic frequency is needed to bring about a spin resonance with an electron than.

Robust electric dipole transition at microwave frequencies for nuclear.
The spin#39;s insensitivity to electric fields yields a solid-state qubit with record coherence times but also renders coupling to other quantum systems very challenging. Here, we describe how to generate a strong electric dipole gt; 100 D at microwave frequencies for the nuclear spin. This is achieved by applying a magnetic drive to the spin of.

Optimal microwave control pulse for nuclear spin polarization.
Abstract: We use nominally forbidden electron-nuclear spin transitions in nitrogen-vacancy NV centers in diamond to demonstrate coherent manipulation of a nuclear spin ensemble using microwave fields at room temperature. We show that employing an off-axis magnetic field with a modest amplitude#92;approx 0.01 T at an angle with respect to the NV natural quantization axes is enough to tilt the direction of the electronic spins, and enable efficient spin exchange with the nitrogen nuclei of. The ability to optically initialize the electronic spin of the nitrogen-vacancy NV center in diamond has long been considered a valuable resource to enhance the polarization of neighboring nuclei, but efficient polarization transfer to spin species outside the diamond crystal has proven challenging. Here we demonstrate variable-magnetic-field, microwave-enabled cross-polarization from the NV. The hydrogen spin line is in the microwave range of frequencies, and within 3 million years, [citation needed] the CMB photons had redshifted out of visible light to infrared; from that time until the first stars, there were no visible light photons. Other than perhaps some rare statistical anomalies, the universe was truly dark.

By a clever combination of microwave pulses in the presence of a static magnetic field B 0 creating an easily detectable feature called a quot;Hahn echoquot; in the current, in an electron-spin resonance setup, Malissa et al. deliberately manipulate the electron spin by rotating it over prescribed angles and detect the resulting disturbed ST spin-pair balance by monitoring the current as a.

Dynamic nuclear polarization DNP results from transferring spin polarization from electrons to nuclei, thereby aligning the nuclear spins to the extent that electron spins are aligned. Note that the alignment of electron spins at a given magnetic field and temperature is described by the Boltzmann distribution under the thermal equilibrium. It is also possible that those electrons are. Nov. 14, 2019 | By Rachel S. Cohen.

For Pe = 0.5, the spin diffusion coefficient would become ca. 1.15 times larger at the final stage of the buildup compared to its value at the initial stage when the nuclear polarization is much lower than 1. The scaling factor for Pe = 0.7, 0.9, and 0.99 would be 1.4, 2.3, and 7.1. Reset image size. Figure 2.
