Query: Quantum Transport of Energy in Controlled Synthetic Quantum Magnets   We introduce a scheme that exploits laser cooling and phonon-mediated
spin-spin interactions in crystals of trapped atomic ions to explore the
transport of energy through a quantum magnet. We show how to implement an
effective transport window to control the flow of energy through the magnet
even in the absence of fermionic statistics for the carriers. This is achieved
by shaping the density of states of the effective thermal reservoirs that arise
from the interaction with the external bath of the modes of the electromagnetic
field, and can be experimentally controlled by tuning the laser frequencies and
intensities appropriately. The interplay of this transport window with the
spin-spin interactions is exploited to build an analogue of the
Coulomb-blockade effect in nano-scale electronic devices, and opens new
possibilities to study quantum effects in energy transport.
