“Basically,” Michele Lazzeri tells PhysOrg.com, “the Born-Oppenheimer adiabatic approximation tells us how atoms are vibrating.” This adiabatic effect is used to describe phonons, which are modes of vibration that have been quantized. “It`s basic textbook stuff in solid state physics,” Lazzeri continues, “but sometimes the Born-Oppenheimer adiabatic approximation fails.”
