Former postdoctoral fellows Marko Petrovic and Manuel Weber publish nonequilibrium work in Physical Review X

Posted in News Story

Professor Freericks led a group including former postdoctoral fellows Marko Petrovic and Manuel Weber on a project that simulates materials with electrons coupled to their lattice vibrations after they have been illuminated by intense laser beams that drive them into a nonequilibrium state. Their approach uses a novel semiclassical scheme that allows simulations to run about 100 times longer than the previous algorithms. This allowed for a number of experiments to be simulated including the excitation and dissipation of the amplitude mode in a charge-density-wave insulator, and the fluence dependence of the x-ray diffraction.
