    "description": "The stability of large Fr\u00f6hlich bipolarons in the presence of a static magnetic field is investigated with the path integral formalism. We find that the application of a magnetic field (characterized by the cyclotron frequence \u03c9c) favors bipolaron formation: (i) the critical electronphonon coupling parameter \u03b1c (above which the bipolaron is stable) decreases with increasing \u03c9c and (ii) the critical Coulomb repulsion strength Uc (below which the bipolaron is stable) increases with increasing \u03c9c. The binding energy and the corresponding variational parameters are calculated as a function of \u03b1, U and \u03c9c. Analytical results are obtained in various limiting cases. In the limit of strong electron-phonon coupling (\u03b1 \u226b 1) we obtain for \u03c9c \u226b 1 that Eestim \u22cd Eestim(\u03c9c = 0) + c(u)\u03c9c/\u03b14 with c(u) an explicitly calculated constant, dependent on the ratio u = U/\u03b1 where U is the strength of the Coulomb repulsion. This relation applies both in 2D and in 3D, but with a different expression for c(u). For \u03c9c \u226b \u03b12\u226b 1 we find in 3D Eestim \u22cd \u03c9c - \u03b12A(u) ln2(\u03c9c/\u03b12), (also with an explicit analytical expression for A(u)) whereas in 2D Eestim2D \u22cd \u03c9c - \u03b1\u221a\u03c9c\u03c0(u-2-\u221a2)/2. The validity region of the Feynman-Jensen inequality for the present problem, bipolarons in a magnetic field, remains to be examined.",
