Different types of coherence: Young-type interference versus Dicke superradiance
Dicke superradiance, ie, the enhanced spontaneous emission of coherent radiation, is often
attributed to radiation emitted by synchronized dipoles coherently oscillating in phase. At the …

Quantum versus classical transport of energy in coupled two-level systems
We consider the problem of energy transport in a chain of coupled quantum systems with the
goal of shedding light on how nonclassical resources can affect transport. We study the …
