A simple scheme to produce strong magnetic fields due cold electron flow in an open-ended coil heated by high power laser pulses is proposed. It differs from previous generation of driven fast current a capacitor-coil target [S. Fujioka et al., Sci. Rep. 3, 1170 (2013)]. The our experiments are measured B-dot detectors and proton radiography, respectively. 205 T field at the center generated free space Iλ2 6.85 × 1014 W cm−2 μm2, where I intensity, λ wavelength. strength proportional Iλ2....
The exact measurement of spin-orbit torque (SOT) in magnetic heterostructures is the basis for a solid understanding its physical mechanism. Although different SOT terms can be properly separated from harmonic Hall voltage analysis, owing to symmetries and magnetic-field dependences, this method may invalid ferromagnetic layer with small coefficient. Here, we develop determine longitudinal measurements. Starting standard total-energy expression system, equations compute corresponding...
The double-shifted magnetic hysteresis loops, which are accompanied by the formation of bi-domain state, normally observed after zero field cooling a demagnetized sample or as-deposited ferromagnetic (FM)/antiferromagnetic (AFM) structures.

We investigated the ferromagnet (FM) and heavy metal (HM) thickness dependence of electric current-induced spin orbit torque (SOT), especially field-like (FL) component in HM/CoFeB/MgO heterostructures. For Pt/CoFeB/MgO Ta/CoFeB/MgO structures, after subtracting dead-layer CoFeB, damping-like (DL) effective field follows 1/tFM dependence, while FL deviates from at ultra-thin FM range, indicating that an extra origination torque, i.e., backflow FM/MgO interface, is responsible for large...

Emitter dephasing is one of the key issues in performance solid-state single photon sources. Among various sources dephasing, acoustic phonons play a central role adding decoherence to emission. Here, we demonstrate, that it possible tune and engineer coherence photons emitted from WSe$_2$ monolayer quantum dot via selectively coupling spectral cavity resonance.

The conventional spin-orbit torque (SOT) and magnetoresistance effect observed in normal-metal (NM)/ferromagnet (FM) bilayers originate from the interaction between magnetic moments spin with in-plane transverse polarization (${\stackrel{\ifmmode \hat{}\else \^{}\fi{}}{\ensuremath{\sigma}}}_{y}$). In FM/NM/FM trilayer structures, presence of an extra FM layer breaks symmetry, resulting other than ${\stackrel{\ifmmode \^{}\fi{}}{\ensuremath{\sigma}}}_{y}$ corresponding SOT. However, study on...
Abstract Ultrafast proton radiography has been frequently used for direct measurement of the electromagnetic fields around laser-driven capacitor-coil targets. The goal is to accurately infer coil currents and their magnetic field generation a robust source that can lead many applications. technique often involves numerical calculations synthetic images reproduce experimental measurements.

Although kinds of topological their promising device applications have been theoretically predicted, experimentally observing is still absent owing mainly the challenges in simultaneously achieving sufficient sensitivity space, momentum, energy resolutions for detecting highly localized mode. Here,...

We introduce a spin ladder with discrete symmetries designed to emulate two-dimensional spin-1/2 boson system at half-filling. Using global properties, such as the structure of topological defects, we establish correspondence between two systems and construct dictionary operators. In particular, translation invariance leads Lieb-Schultz-Mattis constraints for both systems, resulting in exotic deconfined quantum critical points. Subsequently, study detail. An exact duality transformation maps...
We study unusual gapped topological phases where they admit $\mathbb{Z}_N$ fractional excitations in the same manner as topologically ordered phases, yet their ground state degeneracy depends on local geometry of system.

Based this analysis, further show given $\bigl[N\times...
