This paper gives a review of our recent work on the quantum Frenkel–Kontorova model. Using the squeezed state theory … and the quantum Monte Carlo method, we have studied the effects of quantum fluctuations on the Aubry transition and the … behavior of the ground state wave function. We found that quantum fluctuations renormalize the sinusoidal standard map to a …
