The numerical results of the ground-state energy and the derivate of the acoustic polaron in free-standing quantum wells are performed by using the Huybrechts-like variational approach. The criterion for the self-trapping transition of the acoustic polaron in free-standing quantum wells is determined quantitatively. It is found that the critical coupling constant corresponding the discontinuous transition from a quasi-free state to a trapped state of the acoustic polaron in free-standing quantum wells tends to shift toward the weaker electron-phonon coupling with the increasing cutoff wave-vector. Detailed numerical results confirm that the self-trapping transition of acoustic polaron is expected to realize in the free-standing quantum wells of wide-band-gap semiconductors..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
