Kovalev, A.A. (author), Hayden, L.X. (author), Bauer, G.E.W. (author), Tserkovnyak, Y. (author)We theoretically address the quantum dynamics of a nanomechanical resonator coupled to the macrospin of a magnetic nanoparticle by both instanton and perturbative approaches. We demonstrate suppression of the tunneling between opposite magnetizations and destruction of magnetopolaritons (coherent magnetomechanical oscillations) by nanomechanical...journal article 2011

Kovalev, A.A. (author), Zârbo, L.P. (author), Tserkovnyak, Y. (author), Bauer, G.E.W. (author), Sinova, J. (author)Torsional oscillations of a freestanding semiconductor beam are shown to cause spin-dependent oscillating potentials that spin polarize an applied charge current in the presence of intentional or disorder scattering potentials. We propose several realizations of mechanical spin generators and manipulators based on this piezospintronic effect.journal article 2008

Kovalev, A.A. (author), Bauer, G.E.W. (author), Brataas, A. (author)A nanomagnetomechanical system consisting of a cantilever and a thin magnetic film is predicted to display magnetovibrational modes, which should enable applications for sensors and actuators. The “polaritonic” modes can be detected by line splittings in ferromagnetic resonance spectra.journal article 2003
