Experimental demonstration of two-photon magnetic resonances in a single-spin-system of a solid
While the manipulation of quantum systems is significantly developed so far,
achieving a single-source multi-use system for quantum-information processing
and networks is still challenging. A virtual state, a so-called ``dressed
state," is a potential host for quantum hybridizations of quantum physical
systems with various operational ranges. We present an experimental
demonstration of a dressed state generated by two-photon magnetic resonances
using a single spin in a single nitrogen-vacancy center in diamond. The
two-photon magnetic resonances occur under the application of microwave and
radio-frequency fields, with different operational ranges. The experimental
results reveal the behavior of two-photon magnetic transitions in a single
defect spin in a solid, thus presenting new potential quantum and
semi-classical hybrid systems with different operational ranges using
superconductivity and spintronics devices.Comment: 9 pages, 7 figures, Revised manuscript and figure
Dynamical Scaling of Polymerized Membranes
Monte Carlo simulations have been performed to analyze the sub-diffusion
dynamics of a tagged monomer in self-avoiding polymerized membranes in the flat
phase. By decomposing the mean square displacement into the out-of-plane
() and the in-plane () components, we obtain good data
collapse with two distinctive diffusion exponents and , and the roughness exponents
and ,
respectively for each component. Their values are consistent with the relation
from the rotational symmetry. We derive the generalized Langevin equations to
describe the sub-diffusional behaviors of a tagged monomer in the intermediate
time regime where the collective effect of internal modes in the membrane
dominate the dynamics to produce negative memory kernels with a power-law. We
also briefly discuss how the long-range hydrodynamic interactions alter the
exponents.Comment: 6 pages, 5 figures, (Europhysics Letters, in press
