摘要: Abstract The multidimensional bound optical polaron problem is studied using various approximation schemes viz. the Lee, Low, Pines canonical transformation method and its modified versions as developed by Gross Huybrechts, Landau-Pekar variational method, Feynman-Haken path integral formalism. Simple scaling relations are obtained for ground state energy total number of virtual phonons around electron effect dimensionality on phenomena discussed.
