- W2038219210 abstract "The binding of a system of $N$ polarons subject to a constant magnetic field of strength $B$ is investigated within the Pekar-Tomasevich approximation. In this approximation the energy of $N$ polarons is described in terms of a non-quadratic functional with a quartic term that accounts for the electron-electron self-interaction mediated by phonons. The size of a coupling constant, denoted by $alpha$, in front of the quartic is determined by the electronic properties of the crystal under consideration, but in any case it is constrained by $0<alpha<1$. For all values of $N$ and $B$ we find an interval $alpha_{N,B}<alpha<1$ where the $N$ polarons bind in a single cluster described by a minimizer of the Pekar-Tomasevich functional. This minimizer is exponentially localized in the $N$-particle configuration space $R^{3N}$." @default.
