Nanophysics and Quantum Systems

Specific mission

The ‘Nanophysics and Quantum Systems’ Group is devoted to the theoretical modelling and simulation of a broad spectrum of phenomena in quantum physics, ranging from applicative topics like quantum cascade lasers and optoelectronics in nanodevices, to fundamental problems like the effects of correlations, the role of decoherence and dissipation induced by the environment, out of equilibrium phenomena, quantum information, with the common purpose of understanding how novel fundamental quantum effects can be observed in realistic systems.

Main research topics

• Quantum processes in opto-electronic nanomaterials and nanodevices
•  Strongly correlated low-dimensional quantum systems
•  Out of Equilibrium quantum coherent phenomena in fermionic systems
•  Dissipation and decoherence effects in quantum systems
•  Topological phases and materials
•  Quantum Information and Entanglement
•  Quantum phases and dynamics of Bosonic lattice systems
