The perovskite ${\mathrm{SrRuO}}_{3}$ is a prototypical itinerant ferromagnet which allows interface engineering of its electronic and magnetic properties. We report the synthesis investigation atomically flat artificial multilayers with spin-orbit semimetal ${\mathrm{SrIrO}}_{3}$ in combination band-structure calculations Hubbard $U$ term topological analysis. latter reveal an reconstruction e...

The N site open XXZ quantum spin chain with a right non-diagonal boundary and special diagonal left boundary is considered. The boundary non-local charges originally obtained from a field theoretical viewpoint, for the sine Gordon model on the half line, are recovered from the spin chain point of view. Furthermore, the symmetry of the open spin chain is exhibited. More specifically, we show tha...

We discuss the origin of an enigmatic low-temperature behavior some one-dimensional decorated spin systems which was coined pseudo-transition. Tracing out parts results in standard Ising-chain model with temperature-dependent parameters and unexpected thermodynamic quantities correlations chains can be tracked down critical point at H=0 T=0. illustrate this perspective using as examples spin-1/...

Linear chains of spins acting as quantum wires are a promising approach for achieving scalable quantum information processors. Nuclear spins in apatite crystals provide an ideal test bed for the experimental study of quantum information transport, as they closely emulate a one-dimensional spin chain, while magnetic resonance techniques can be used to drive the spin chain dynamics and probe the ...

We calculate the local correlation functions of charge and spin for the one-chain and two-chain Hubbard model using the density matrix renormalization group method and the recursion technique. Keeping only finite number of states we get good accuracy for the low energy excitations. We study the charge and spin gaps, bandwidths and weights of the spectra for various values of the on-site Coulomb...
