An arrangement of spins known as a meron turns out to be easier to make in momentum space than in real space.
A skyrmion is a region where the orientation of a vector field—such as a magnet’s spin…

Probing interplay of topological properties and electron correlation in TaIrTe4 via nonlinear Hall effect
The lattice structure of a few-layer TaIrTe4 is shown in Fig. 1a with a mirror plane \({M}_{\hat{{{{\rm{a}}}}}}\). As restricted by symmetry, NLHE is nonzero along the \(\hat{{{{\rm{b}}}}}\)-axis in response to a perpendicular driving current,

Waveform-controlled field synthesis of sub-two-cycle pulses at the 100 TW peak power level
System infrastructure
The set-up of the Light Wave Synthesizer 100 (LWS100) is shown in Fig. 1. It starts with the first part of the front end, a Pharos pump laser (Light Conversion), including a 75-MHz mode-locked Yb:KGW (potassium gadolinium…

Universal condensation threshold dependence on pump beam size for exciton-polaritons
Sample characterization
We conducted experiments using three AlGaAs-based samples. According to their origin, we dub them “KIST”, “KAIST 1”, and “KAIST 2”. The KIST sample was used in ref. 65, and KAIST samples are distant chips from…

Nonlocal electrical detection of reciprocal orbital Edelstein effect
Measurement of orbital accumulation in a nonlocal transport device structure
We investigated the OAM distribution using a nonlocal lateral transport structure1,31,32,33,34,35,36,37 (Fig. 1a, b), where the nonlocal resistance signals arise from…

A holistic view of the dynamics of long-lived valley polarized dark excitonic states in monolayer WS2
Tr-ARPES experiment on 1 L WS2: Valley-selective excitation
Our sample is an exfoliated WS2 monolayer, transferred on a thin hBN buffer layer supported by a conducting Si substrate (see Methods). The TR-ARPES experiments (Fig. 1b) were…
