The adiabatic quantum motors [1] are nanometric
scale's machines which can provide a mechanic work
from a flux of quantum particles. So, it's necessary a
deep knowledge of the current induce forces and yours
non-conservative contributions. In this work, we study a
one dimensional system which consists in a quantum
dot connected with to reservoirs, under a non
interaction particles tight binding model [2]. Over this
system, we analyzed the equilibrium forces, non
equilibrium forces and energy dissipation through green
functions and scattering matrix [3]. Our main goal is the
role of resonants states on the system, the dynamical
phase transitions of localized -non localized states[4,5]
and the correlations with current induced forces over
the system. With this aim in mind, we want to
understand how we can perform a nanomotor or
another kind of nano-electro-mechanical devices.
