  • Odd-parity effect and scale-dependent viscosity in atomic quantum gases

    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

    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

    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

    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

    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…

  • A free-field method of characterizing anisotropy in porous media

    A free-field method of characterizing anisotropy in porous media

    Analytical results

    We consider porous materials that are homogeneous (i.e., whose properties are spatially uniform) and whose solid phase is assumed to be motionless. We define a reference coordinate system \(({\rm{O}}, {\bf{e}}_{1}, {\bf{e}}_{2},…

  • Localization in materials with several conducting bands as a method to boost superconductivity

    Localization in materials with several conducting bands as a method to boost superconductivity

    The model

    We consider a superconductor with two coupled subsystems, referred to as bands, each with its own charge carriers. This model can describe not only two-band superconductors but also layered materials where the subsystems are spatially…

    Experiment Recreates The Universe’s Very First Chemical Reactions : ScienceAlert

    The first chemical reactions in the wake of the Big Bang have been recreated for the first time in conditions similar to those in the baby Universe.
