<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Times New
Roman","serif";color:black">The expression
Coulomb drag is used to describe the mutual friction due to
the Coulomb electrostatic interaction between electric
currents that flow in adjacent layers of semiconductor
material. This phenomenon provides a new coupling mechanism
(alternative to the conventional inductance and capacitance)
between spatially separated elements of nano-electronic
circuitry. From a more fundamental point of view, it can be a
revealing probe of novel states of electronic matter. More
recently, the phenomenon of spin Coulomb drag, whereby
friction occurs between currents of opposite spin orientation
in a single electronic layer, has attracted attention in the
context of a new branch of electronics, which is known as
"spintronics". This phenomenon has been observed and
quantitatively verified in experiments. Lately a new drag
mechanism, based on energy rather than momentum exchange has
been suggested for systems consisting of two parallel carbon
monolayers (graphene). In this talk I review some of the
latest theoretical and experimental developments on Coulomb
drag and spin Coulomb drag in novel quantum systems such as
graphene, topological insulators and cold atoms.<o:p></o:p></span></p>
