Biography

Simeon obtained his Master degree in theoretical physics in the sector of Nuclear and Particle Physics from the National and Kapodistrian University of Athens, Greece. His main focus was the development of path integral techniques in cavity quantum electrodynamics. He moved for his PhD at the University of Hamburg (Center for Optical Quantum Technologies). His research was devoted on the correlated nonequilibrium quantum dynamics of many-body atomic systems with a particular emphasis on excitation processes in optical lattices, pattern formation and the physics of polarons. Following his PhD (summa cum laude) he received the Lenz-Ising Prize for outstanding junior scientists (University of Hamburg). Afterwards, Simeon was an ITAMP postdoctoral Harvard fellow working on engineering entanglement based processes and magnetic phenomena appearing in many-body multicomponent systems ranging from quasiparticles and droplets to long-range settings. His theoretical tools are based on ab-initio approaches, beyond mean-field frameworks and the construction of effective Hamiltonian models.
