Fratini, S. Valenzuela, B. Baeriswyl, Dionys 2004-01-16 A one-dimensional tight-binding model of electrons with long-range Coulomb interactions is studied in the limit where double site occupancy is forbidden and the Coulomb coupling strength V is large with respect to the hopping amplitude t. The quantum problem of a kink–antikink pair generated in the Wigner lattice (the classical ground state for t=0) is solved for fillings n=1/s, where s is an integer larger than 1. The pair energy becomes negative for a relatively high value of V, Vc/t≈s³. This signals the initial stage of the quantum melting of the Wigner lattice. application/pdf https://folia.unifr.ch/global/documents/299719 https://folia.unifr.ch/documents/299719/files/1_baeriswyl_iqm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.synthmet.2003.10.030 info:eu-repo/semantics/openAccess License undefined Synthetic Metals. - 2004, vol. 141, no. 1-2, p. 193-196 Wigner lattice quantum melting φ Particles phi particles kink–antikink pairs info:eu-repo/classification/udc/53 Incipient quantum melting of the one-dimensional Wigner lattice http://purl.org/coar/resource_type/c_6501
