Fluctuations and photon statistics in quantum metamaterial near the superradiant transition
D. S. Shapiro, A. N. Rubtsov, S. V. Remizov +2
The analysis of single-mode photon fluctuations and their counting statistics at the superradiant phase transition is presented. The study concerns the equilibrium Dicke model in a…
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…
