Observation of local and global plasma oscillations using fast camera diagnostics

Initially, we analyzed the measurement results from the fast camera results to gain insights into the internal structure of the plasma over time (see “Methods”)….

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…
