Separable Schmidt modes of an entangled state

Abstract

Two-Photon Spectral Amplitude of entangled states is engineered to produce a losslessly decomposition in non-overlapping single Schmidt modes. The method relies on spontaneous parametric down-conversion pumped by a comb-like spectrum radiation

Influence of varying magnetic order in an external magnetic field on the electronic structure and Fermi surface within the t–J model

“…We should emphasize the decreasing SW scale for spindown component with increasing magnetic field. Decreasing a magnetic field further down to h = 0.5J when magnetic moments form a slightly tilted AFM structure, at low energy for spin-up component we can recognize the picture similar to a dispersion strongly affected by spin fluctuations as was obtained within different methods [18,[41][42][43][44][45][46]. The whole band can be considered as split into two major subbands in agreement with quantum Monte-Carlo calculations [34].…”
