Dissipative quantum many-body systems


Dissipation is usually seen as an enemy of coherent evolution, as a decohering process that removes quantum features from the state of a system. It has recently become clear, however, that engineered dissipation can be an ally and help in robust state preparation and manipulation. The interplay between Hamiltonian interactions and open systems dynamics gives rise to new kinds of quantum phase transitions and criticality. We investigate several aspects of this, ranging from more condensed-matter oriented questions, tasks of quantum information processing to mathematical questions relating spatial correlations and mixing.
