Abstract: | We explore a semi-classical scheme for cooling and excitation of mechanical oscillations of a suspended carbon nanotube which
is incorporated as a deflection-sensitive resistor in an LRC-circuit. The active feedback consists of a magnetically induced
Lorentz force. We show that, for feasible experimental parameters, we can obtain self-sustained oscillations or cooling by
several orders of magnitude. |
