Effects of spin-orbit interaction and electron correlations in strontium titanate

Sergei Urazhdin, Ekram Towsif, Alexander Mitrofanov

We show that the Bloch states in the conduction band of SrTiO $_{3}$ arise from the interplay between highly anisotropic hopping in sub-bands derived from the Ti $t_{2 g}$ orbitals and…

Orbital entanglement mechanism of superconductivity in cuprates

Alexander Mitrofanov, Sergei Urazhdin

We utilize a 1d Hubbard model to show that the superconductivity in cuprate superconductors likely arises due to the orbital entanglement between holes in the copper oxide plane me…

Exchange bias without directional anisotropy in Permalloy/CoO bilayers

Alexander Mitrofanov, Guanxiong Chen, Alexander Kozhanov +1

We utilize transverse ac susceptibility measurements to characterize magnetic anisotropy in archetypal exchange-bias bilayers of ferromagnet Permalloy (Py) and antiferromagnet CoO.…

Effects of the dynamical magnetization state on spin transfer

Neil Tramsen, Alexander Mitrofanov, Sergei Urazhdin

We utilize simulations of electron scattering by a chain of dynamical quantum spins, to analyze the interplay between the spin transfer effect and the magnetization dynamics. We sh…

Energy and momentum conservation in spin transfer

Alexander Mitrofanov, Sergei Urazhdin

We utilize simulations of spin-polarized electron scattering by a chain of localized quantum spins to show that energy and linear momentum conservation laws impose strong constrain…

$K^{+} \to μ^{+} ν_{μ} ν ν ˉ$ and $K^{+} \to e^{+} ν_{e} ν ν ˉ$ decays within the Chiral Perturbation Theory

D. Gorbunov, A. Mitrofanov

Decays $K^{+} \to μ^{+} ν_{μ} ν ν ˉ$ and $K^{+} \to e^{+} ν_{e} ν ν ˉ$ are examined to the leading order in momenta in the framework of Chiral Perturbation Theory. P…

Phase Locked Loop of the Spin-Torque Nanooscillator

Alexander A. Mitrofanov, Ansar R. Safin, Nicolay N. Udalov

We have studied the dynamics of a spin-torque nanooscillator's (STNO) phase locked loop (PLL) generating microwave oscillations in a broad range of frequencies under the effect of…
