Spin dynamics of a solid-state qubit in proximity to a superconductor
Richard Monge, Tom Delord, Nicholas Proscia +11
A broad effort is underway to understand and harness the interaction between superconductors and spin-active color centers with an eye on the realization of hybrid quantum devices…
Ultrafast opto-magnetic effects induced by nitrogen-vacancy centers in diamond crystals
Ryosuke Sakurai, Yuta Kainuma, Toshu An +2
The current generation of quantum sensing technologies using color centers in diamond crystals is primarily based on the principle that the resonant microwave frequency of the lumi…
Temperature-dependent second-harmonic generation from color centers in diamond
Aizitiaili Abulikemu, Yuta Kainuma, Toshu An +1
Under infrared ultrashort pulse laser stimulation, we investigated temperature-dependent second-harmonic generation (SHG) from nitrogen-vacancy (NV)-introduced bulk diamond. The SH…
Second-Harmonic Generation in Bulk Diamond Based on Inversion Symmetry Breaking by Color Centers
Aizitiaili Abulikemu, Yuta Kainuma, Toshu An +1
Breaking inversion symmetry in solids plays a central role in nonlinear optics because it can change material properties, such as producing even-order nonlinear optical (NLO) effec…
Local heat emission due to unidirectional spin-wave heat conveyer effect observed by lock-in thermography
Yuta Kainuma, Ryo Iguchi, Dwi Prananto +4
Lock-in thermography measurements were performed to reveal heat source distribution induced by the unidirectional spin-wave heat conveyer effect (USHCE) of magnetostatic surface sp…
Probing thermal magnon current mediated by coherent magnon via nitrogen-vacancy centers in diamond
Dwi Prananto, Yuta Kainuma, Kunitaka Hayashi +3
Currently, thermally excited magnons are being intensively investigated owing to their potential in computing devices and thermoelectric conversion technologies. We report the dete…
Giant nonlinear optical effects induced by nitrogen-vacancy centers in diamond crystals
Mari Motojima, Takara Suzuki, Hidemi Shigekawa +3
We investigate the effect of nitrogen-vacancy (NV) centers in single crystal diamond on nonlinear optical effects using 40 fs femtosecond laser pulses. The near infrared femtosecon…
Long-distance excitation of nitrogen-vacancy centers in diamond via surface spin waves
Daisuke Kikuchi, Dwi Prananto, Kunitaka Hayashi +7
Coherent communication over mesoscale distances is a necessary condition for the application of solid-state spin qubits to scalable quantum information processing. Among other rout…
Spin mixing conductance at a well-controlled platinum/yttrium iron garnet interface
Z. Qiu, K. Ando, K. Uchida +6
A platinum (Pt)/yttrium iron garnet (YIG) bilayer system with a well-controlled interface has been developed; spin mixing conductance at the Pt/YIG interface has been studied. Crys…
Heat-induced damping modification in YIG/Pt hetero-structures
M. B. Jungfleisch, T. An, K. Ando +7
We experimentally demonstrate the manipulation of magnetization relaxation utilizing a temperature difference across the thickness of an yttrium iron garnet/platinum (YIG/Pt) heter…
A comparsion of force sensors for atomic force microscopy based on quartz tuning forks and length extensional resonators
Franz J. Giessibl, Florian Pielmeier, Toyoaki Eguchi +2
The force sensor is key to the performance of atomic force microscopy (AFM). Nowadays, most AFMs use micro-machined force sensors made from silicon, but piezoelectric quartz sensor…
Acoustic spin pumping as the origin of the long-range spin Seebeck effect
Ken-ichi Uchida, Hiroto Adachi, Toshu An +5
The spin Seebeck effect (SSE) is known as the generation of 'spin voltage' in a magnet as a result of a temperature gradient. Spin voltage stands for the potential for spins, which…
