Quantum Engineered Systems

Our research is centered on the study of electronic, atomic, and photonic systems, with their modern ramifications such as topology, out-of-equilibrium, controllability, and its consequences for fundamental physics and device applications.

The research in the group is divided into three main pillars, (i) quantum electronic transport, (ii) material properties and quantum simulation of matter and light-matter systems, and (iii) dynamical nonlinear phenomena. We harness a variety of analytical and numerical methods to propose new effects, and explain observed phenomena. As a result, we maintain strong synergy with experiments.

In the context of mesoscopic transport, we analyze the out-​of-equilibrium interplay between quantum transport and quantum measurement. This involves translation of fundamental ideas and protocols from measurement theory to realistic microscopic models. Such adaptation of purely theoretical ideas to predicted transport signatures has led to various applications in amplified sensing, quantum information processing, and detection of fractional particle statistics.

Additionally, we study the manifestation and demonstration of exotic material properties in coupled light and matter metamaterials, which is a very promising route for optoelectronics. Specifically, we analyze the impact of the interplay between topology, (quasi-​)disorder, interaction, and parametric driving in engineered driven-​dissipative photonic crystals and ultracold-​atomic systems. Conjoining any pair of the above ingredients leads to very active fields of research, such as, many-​body localization, Floquet topological insulators, and topological quasicrystals.
