Variational study of two-impurity spin-boson model with a common Ohmic bath: Ground-state phase transitions
Nengji Zhou, Yuyu Zhang, Zhiguo Lu +1
By means of a trial wave function, the multi-D ansatz, extensive variational calculations with more than ten thousand parameters have been carried out to study quantum phase tr…

Fast, accurate simulation of polaron dynamics and multidimensional spectroscopy by multiple Davydov trial states
Nengji Zhou, Lipeng Chen, Zhongkai Huang +3
By employing the Dirac-Frenkel time-dependent variational principle, we study the dynamical properties of the Holstein molecular crystal model with diagonal and off-diagonal excito…
