Extending the Feynman variational principle and analytical methods to lattice polarons
S. N. Klimin, J. Tempere, M. Houtput +6
We develop and compare several analytical approximations for the ground state and zero-temperature polaron dispersion in finite-width, nonparabolic conduction bands. The main focus…
