Analytical results for a 2D electron gas in a (1/r)-inhomogeneous magnetic field are presented, which reveal a distorted Landau level structure with unique features, e.g., different Hall conductivity phases, or perfect absorbance from spin-orbit interaction. Furthermore, recent ab-initio results are shown for molecules under collective vibrational strong coupling (VSC) in optical cavities. They suggest the formation of a cavity induced polarization glass phase, which alters molecular properties not only collectively but also locally. Finally, quantum thermal effects under VSC are discussed for a single HD+ molecule that is solved numerically exactly.
