Model and Zeeman effects

The anisotropic Hamiltonian for ZrTe₅ in a finite perpendicular magnetic field B, can be written as¹⁹

Scientists have linked nuclear spins inside silicon chips, marking a leap toward scalable…

Early discussions of the electric polarization induced by non-collinear spin configurations and spin spirals include phenomenological descriptions, as in earlier Ref. ³ or in Ref. ⁴³, and microscopic mechanisms, such as the purely electronic one…

Physical and chemical characterization

The Co-N-rGO was synthesized using a previously established and reproducible microwave assisted method, as reported in our earlier work (refs. ^25,45,46) and described in detail in the Supporting Information….

We now describe the numerical model used to simulate QZD for a two-proton system. Our goal is to study the effect of frequent position measurements on the evolution of the wavefunction and estimate the conditions required for spatial…

Vortex line profiles: qualitative features

In a realistic scenario, the Crow instability may be triggered in a trapped Bose-Einstein condensate when the trapping potential landscape is locally inhomogeneous in the vicinity of a pair of…

First principle calculations of electron and phonon properties of Sb_xSe_y films

The calculated dielectric permittivities ε_∞ (electronic contribution) and ε_ion (ionic contribution) of Sb₂Se₃ crystal (Table 2) are in acceptable agreement with…

As shown in Fig. 1a,b, the refractive index and absorption coefficient exhibit frequency-dependent variations that distinguish normal and cancerous oral cells in the THz range. Both cell types display a sharp decline in refractive index as…
