Device and experimental principle

The device schematic and measurement setup are shown in Fig. 1. The device consists of three parallel Pt wires deposited on a 150 nm-thick YIG layer grown by liquid phase epitaxy on a Gd₃Ga₅O₁₂ substrate. The…

The measurements are performed on a two-dimensional electron gas made in high mobility GaAs/Ga(Al)As heterojunction with electron density n_s = 1.11 10¹⁵ m⁻² and zero field mobility μ = 300 m² V⁻¹ s⁻¹, see SM. The filling…

Three-angle precession protocols and the classical inequality

Tsirelson’s precession protocol and its generalisations involve uniformly precessing observables. A pair of observables A_x(θ) and A_y(θ) with a parametric dependence on θ are…

Bacterial motility in microchannels

To study the dynamics in microchannels, we use Bradyrhizobium diazoefficiens, although the theory we present is of general applicability. These bacteria move through soil pores to penetrate the roots of soybean…

Crystallography

The crystal structure and atomic composition of YMn₆Sn_5.45Ga_0.55 (Y166-Ga) were determined using single crystal X-ray diffraction. Similar to the parent compound YMn₆Sn₆ (Y166), Y166-Ga adopts a hexagonal P6/mmm structure…

\({{\mathbb{Z}}}_{2}\) lattice gauge theory

We consider a 1 + 1-dimensional model of spinless and massless fermions coupled to a \({{\mathbb{Z}}}_{2}\) gauge field:

C-DMs

DMs, both unconditional and conditional, have recently gained popularity in various fields such as computer vision for image generation and enhancement³⁶, audio generation³⁷, text-to-video synthesis³⁸, and have also shown promising results…

Experiments are carried out in a large aspect ratio channel, considerably exceeding domain sizes of most earlier studies. Specifically, the channel’s dimensions are (L_x, L_y, L_z) = (4000h, 2h, 490h), where L_x, L_y and L_z are lengths in the…

Ultracold sample preparation

We prepare a quantum degenerate ultracold sample of ⁸⁷Sr atoms using, as an initial step, standard laser cooling techniques. Then, 2.5(1) × 10⁶ atoms at a temperature of 6 μK are loaded into a far-off-resonant…

Fluctuation measurements

We measure the quasiparticle relaxation time (τ) and density (n_qp) in a 40-nm-thick disordered β-Ta film²⁶, which is patterned as the inductor in a microwave resonator. The device is shown in Fig. 1a. The β-Ta film is…
