Kinetic turbulence drives MHD equilibrium change via 3D reconnection
The 3D helical flux ropes in VEST
Two essential magnetic field components, the poloidal and toroidal fields, are driven by external coils of VEST51, resulting in a 3D helical vacuum magnetic field configuration. Two flux ropes are discharged by…

Odd-parity effect and scale-dependent viscosity in atomic quantum gases
Quasiparticle lifetimes
We first establish the odd-even effect in the lifetimes of the odd and even parity modes of the quasiparticle distribution at low temperatures on the BCS side of the normal region of the BCS-BEC crossover (where a…

The effect of cooling rate and content of niobium on the structure, wear and corrosion resistance of CoCrFeNiNbx high entropy alloys
Figure 1 shows the X-ray diffraction (XRD) patterns of the CoCrFeNiNbx alloys solidified with different cooling rates. All of the alloys are characterized by the dual-phase microstructure consisting of face-centred cubic (FCC) solid solution and…

Thermal behavior of the Klein Gordon oscillator in a dynamical noncommutative space
Methods and numerical results
In this part, we investigate the effect of DNC and flat NC spaces on the thermal properties of the KG oscillator. So, in the framework of statistical physics, these properties are determined using the partition…

Single-photon counting pixel detector for soft X-rays
Detector description
LGAD sensors are based on an n-in-p silicon junction and incorporate an additional layer, moderately doped with the same polarity as the substrate. This region, typically created via ion implantation and referred to as the…

Confinement of charge carriers in gapped bilayer graphene within magnetic and electrostatic barriers
In this study, we investigate the transport properties of BLG by calculating the transmission and conductance of the system under the influence of a perpendicular magnetic field and varying scalar potentials applied to the layers. The BLG system…

Radiation Shield Improves Optical Clocks
• Physics 18, s108
A new experimental design eliminates the top source of clock uncertainty.
Optical lattice clocks (OLCs) are among the world’s best atomic clocks. Their largest source of uncertainty results from the…
