An international team of researchers (USA – Rice University, Argonne National Laboratory, Purdue University, Japan) created resonance frequency shift in solid gallium arsenide in a strong perpendicular magnetic field. They hybridize with the “vacuum” electromagnetic field in the cavity to form polaritons. They have demonstrated Bloch–Siegert shift, which is induced by the ultra-strong coupling of matter with the counter-rotating component of the vacuum fluctuation field in a cavity. The research could aid in the development of quantum computers… read more. Open Access TECHNICAL ARTICLEÂ
