Magnetized Fast Isochoric Laser Heating for Efficient Creation of Ultra-High-Energy-Density States
Shohei Sakata, Seungho Lee, Tomoyuki Johzaki +36
The quest for the inertial confinement fusion (ICF) ignition is a grand challenge, as exemplified by extraordinary large laser facilities. Fast isochoric heating of a pre-compresse…
New and Improved Algorithms for Unordered Tree Inclusion
Tatsuya Akutsu, Jesper Jansson, Ruiming Li +2
The tree inclusion problem is, given two node-labeled trees and (the ``pattern tree'' and the ``target tree''), to locate every minimal subtree in (if any) that can be…
Experimental demonstration of two-photon magnetic resonances in a single-spin-system of a solid
Toshiyuki Tashima, Hiroki Morishita, Norikazu Mizuochi
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 cha…
Microscopic origin of electric-field-induced modulation of Curie temperature in cobalt
Fuyuki Ando, Kihiro T. Yamada, Tomohiro Koyama +5
The Curie temperature is one of the most fundamental physical properties of ferromagnetic materials and can be described by Weiss molecular field theory with the exchange interacti…
Correlation between Compensation Temperatures of Magnetization and Angular Momentum in GdFeCo Ferrimagnets
Yuushou Hirata, Duck-Ho Kim, Takaya Okuno +8
Determining the angular momentum compensation temperature of ferrimagnets is an important step towards ferrimagnetic spintronics, but is not generally easy to achieve it experiment…
Transport Coefficients of Dirac Ferromagnet: Effects of Vertex Corrections
Junji Fujimoto
As a strongly spin-orbit coupled metallic model with ferromagnetism, we have considered an extended Stoner model to the relativistic regime, named Dirac ferromagnet in three dimens…
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…
Electric field-induced creation and directional motion of domain walls and skyrmion bubbles
Chuang Ma, Xichao Zhang, Jing Xia +7
Magnetization dynamics driven by an electric field could provide long-term benefits to information technologies because of its ultralow power consumption. Meanwhile, the Dzyaloshin…
Extension of the Coherence Time by Generating MW Dressed States in a Single NV Centre in Diamond
Hiroki Morishita, Toshiyuki Tashima, Disuke Mima +5
Nitrogen-vacancy (NV) centres in diamond hold promise in quantum sensing applications. A major interest in them is an enhancement of their sensitivity by the extension of the coher…
Intrinsic and Extrinsic Spin Hall Effects of Dirac Electrons
Takaaki Fukazawa, Hiroshi Kohno, Junji Fujimoto
We investigate the spin Hall effect (SHE) of electrons described by the Dirac equation, which is used as an effective model near the -points in bismuth. By considering short-ran…
Coherent Terahertz Spin-Wave Emission Associated with Ferrimagnetic Domain Wall Dynamics
Se-Hyeok Oh, Se Kwon Kim, Dong-Kyu Lee +5
We theoretically study the dynamics of ferrimagnetic domain walls in the presence of Dzyaloshinskii-Moriya interaction. We find that an application of a DC magnetic field can induc…
Contributions of Co and Fe orbitals to Perpendicular Magnetic Anisotropy of MgO/CoFeB Bilayers with Spin-Orbit-Torque-Related (Ta, W, IrMn, and Ti) Underlayers
Sanghoon Kim, Seung-heon Chris Baek, Mio Ishibashi +9
We study the perpendicular magnetic anisotropy (PMA) of the CoFeB/MgO bilayers in contact with W, Ta, IrMn and Ti which has been suggested as the spin-orbit-torque-related underlay…
Origin of threshold current density for asymmetric magnetoresistance in Pt/Py bilayers
Tian Li, Sanghoon Kim, Seung-Jae Lee +7
An asymmetric magnetoresistance (MR) is investigated in Py/Pt bilayers. The asymmetric MR linearly increases with current density up to a threshold, and increases more rapidly abov…
Finite shot noise and electron heating at quantized conductance in high-mobility quantum point contacts
Tatsuya Muro, Yoshitaka Nishihara, Shota Norimoto +8
We report a precise experimental study on the shot noise of a quantum point contact (QPC) fabricated in a GaAs/AlGaAs based high-mobility two-dimensional electron gas (2DEG). The c…
Microscopic Origin of Interfacial Dzyaloshinskii-Moriya Interaction
Sanghoon Kim, Kohei Ueda, Gyungchoon Go +15
Chiral spin textures at the interface between ferromagnetic and heavy nonmagnetic metals, such as Neel-type domain walls and skyrmions, have been studied intensively because of the…
