Spin transfer torque induced paramagnetic resonance
Alexey M. Shakirov, Alexey N. Rubtsov, Pedro Ribeiro
We show how the spin-transfer torque generated by an ac voltage may be used to excite a paramagnetic resonance of an atomic spin deposited on a metallic surface. This mechanism is…
Relaxation and decoherence of qubits encoded in collective states of engineered magnetic structures
Alexey M. Shakirov, Alexey N. Rubtsov, Alexander I. Lichtenstein +1
The quantum nature of a microscopic system can only be revealed when it is sufficiently decoupled from surroundings. Interactions with the environment induce relaxation and decoher…
Role of coherence in transport through engineered atomic spin devices
Alexey M. Shakirov, Yulia E. Shchadilova, Alexey N. Rubtsov +1
We give a further step in the quantum mechanical description of engineered atomic spin structures by deriving a master equation of the Redfield type that governs the dynamics of th…
Quantum statistical ensemble for emissive correlated systems
Alexey M. Shakirov, Yulia E. Shchadilova, Alexey N. Rubtsov
Relaxation dynamics of complex quantum systems with strong interactions towards the steady state is a fundamental problem in statistical mechanics. The steady state of subsystems w…
Modeling the metastable dynamics of correlated structures
Alexey M. Shakirov, Sergey V. Tsibulsky, Andrey E. Antipov +2
Metastable quantum dynamics of an asymmetric triangular cluster that is coupled to a reservoir is investigated. The dynamics is governed by bath-mediated transitions, which in part…
