Applied Theoretical Physics - From Quantum Mechanics to Nanotechnology

We apply the methods of theoretical condensed matter physics to understand the properties of condensed matter structures on the nanoscale, motivated by scientifi c curiosity, new experimental discoveries, and potential applications. Many of our activities are centered on the quantum mechanics of the spin degree of freedom of the electron. The science and technology of studying and controlling the coupled spin and charge current is called spintronics. Only recently, it has been fully recognized that heat currents are strongly coupled to the spin as well, leading to a new fi eld of spin caloritronics. Here we study the spin Seebeck effect. Our research on spin mechanics is devoted to the coupling of the magnetic and mechanical degrees of freedom, such as nanoscopic version of the Barnett and Einstein-de Haas effects.

A classical analogue of the Barnett effect from S. J. Barnett, Rev. Mod. Phys. 7, 129 (1935). When the gyroscope built into the axis A spins, a rotation around the C axis modifies the tilt angle θ.
