Query: Ground state cooling of nanomechanical resonators by electron transport   We discuss two theoretical proposals for controlling the nonequilibrium
steady state of nanomechanical resonators using quantum electronic transport.
Specifically?, we analyse two approaches to achieve the ground-state cooling of
the mechanical vibration coupled to a quantum dot embedded between (i)
spin-polarised contacts or (ii) a normal metal and a superconducting contact.
Assuming a suitable coupling between the vibrational modes and the charge or
spin of the electrons in the quantum dot, we show that ground-state cooling of
the mechanical oscillator is within the state of the art for suspended carbon
nanotube quantum dots operating as electromechanical devices.
