A team of researchers
from IFISC (UIB-CSIC) has demonstrated that a quantum chiral conductor driven
by an alternating current voltage can operate with efficiencies much higher
than the hitherto insurmountable Carnot limit. In the paper, published in
Nature Communications, the authors propose a general class of quantum devices
driven periodically by alternating current (AC), which can convert heat into
electricity with an increased performance.
One of the
implications of the second law of the...
