Abstract Imaging of the dust continuum emitted from disks around nearby protostars reveals diverse substructure. In recent years, theoretical efforts have been intensified to investigate how far intrinsic dynamics protoplanetary (PPDs) can lead such features. Turbulence in realm non-ideal magnetohydrodynamics (MHD) is one candidate for explaining generation zonal flows which local enhancements. Adopting a radially varying cylindrical disk model, and considering combinations vertical...
The fusion of non-Abelian anyons or topological defects is a fundamental operation in measurement-only quantum computation. In superconductors, this amounts to determination the shared fermion parity Majorana zero modes. As step towards this, we implement single-shot interferometric measurement indium arsenide-aluminum heterostructures with gate-defined nanowire. interferometer formed by tunnel-coupling proximitized nanowire dots. causes state-dependent shift these dots' capacitance up 1 fF....
We apply the picket fence treatment to model effects brought about by spectral lines on thermal structure of irradiated atmospheres. The may be due purely absorption processes, coherent scattering processes or some combination and scattering. If arise as a pure process, surface layers atmosphere are cooler whereas this cooling is completely absent if isotropic also lead warming deeper atmosphere. is, however, independent nature line formation. Accounting for in shortwave longwave continuum...
The effect of magnetic field diffusion on the stability accretion disks is a problem that has attracted considerable interest late. In particular, Hall potential to bring about remarkable changes in dynamical behavior are without parallel. this paper, we conduct systematic examination linear eigenmodes weakly magnetized differentially rotating gas with special focus diffusion. We first develop geometrical representation and provide detailed quantitative description polarization properties...
We conduct a comprehensive axisymmetric, local linear mode analysis of stratified, differentially rotating disk permeated by toroidal magnetic field which could provide significant pressure support. In the adiabatic limit, we derive new stability criteria that differs from one obtained for weak fields with poloidal component and reduces continuously to hydrodynamic Solberg-H{\o}iland criteria. Three fundamental unstable modes are found in locally isothermal limit. They comprise overstable:...
