Weyl-like magnon excitations in ordered magnets have attracted significant recent attention. Despite the tantalizing physics and application prospects, experimental observation of Weyl magnons is still challenging owing to their extraordinarily high frequency that not accessible microstrip antenna technique. Here we predict gigahertz collective dynamics dipolar-coupled magnetic vortices arrange...

Massless chiral fermions emergent in inversion symmetry-breaking Weyl semimetals (WSMs) reside the vicinity of multiple low symmetry nodes and thus acquire strongly anisotropic dispersion. We investigate longitudinal electromagnetic modes two-component degenerate plasma relevant to realistic band structure type-I WSM. show that actual spectrum three dimensional collective density excitations Ta...

the objective of the present study was to estimate heritability values for some performance and egg quality traits of native fowl in isfahan breeding center using reml and bayesian approaches. the records were about 51521 and 975 for performance and egg quality traits, respectively. at the first step, variance components were estimated for body weight at hatch (bw0), body weight at 8 weeks of a...

Weyl semimetal (WSM), a novel state of quantum matter, hosts fermions as emergent quasiparticles resulting from the breaking either inversion or time-reversal symmetry. Magnetic WSMs that arise broken symmetry provide an exceptional platform to understand interplay between magnetic order and physics, but only few have been realized. Here, we identify CeAlSi new noncentrosymmetric WSM via angle-...

Cougar (Puma concolor) management in Oregon is unique because hunting cougars with dogs was allowed through the 1994 hunting season, but thereafter Ballot Initiative Measure 18 prohibited the use of dogs to pursue cougars. Since 1995, hunting seasons have become increasingly longer withmore tags sold. The effects of changing management structure on survival rates and causes of mortality of coug...

Evolutionary Algorithms are recognized to be efficient to deal withMulti-objective Optimization Problems(MOPs) which are difficult to be solved with traditional methods. Here a newMulti-objective Optimization Evolutionary Algorithm named DGPS which is compound with Geometrical Pareto Selection Method (GPS), Weighted SumMethod (WSM) and Dynamical Evolutionary Algorithm (DEA) is proposed. Some fa...

The discovery of Weyl semimetals (WSMs) has fueled tremendous interest in condensed matter physics. WSMs require breaking either inversion symmetry (IS) or time-reversal (TRS); they can be categorized into type-I and type-II WSMs, characterized by un-tilted strongly tilted cones respectively. Type-I with IS TRS have been realized experimentally, but TRS-breaking WSM still remains elusive. In th...

Since the discovery of Harper-Hofstadter model, it has been known that condensed matter systems with periodic modulations can be promoted to nontrivial topological states emergent gauge fields in higher dimensions. In this paper, we develop a general procedure compute dimensions associated low-dimensional (charge- and spin-) density wave modulations. We construct two-dimensional (2D) models hig...

We study the effects of tunneling between a Weyl semimetal (WSM) and simple parabolic band. When coupled to nonmagnetic band, interface two exhibits main phenomena. First, WSM's chiral arc state lowers in energy, second, previously extended WSM becomes localized is lowered energy. Together these surface bound states create new closed orbit momentum space, noticeable spin-dependent asymmetry spe...
