摘要：

We study the dependence of quark condensate Sigma on an external magnetic field. For weak fields, it rises linearly: Sigma(H) = Sigma(0)[1 + eH ln 2/(16 pi(2)F(pi)(2)) + ...]. M-pi and F-pi are also shifted so that the Gell-Mann-Oakes-Renner relation is satisfied. In the strong field region, Sigma(H) proportional to (eH)(3/2). (C) 1997 Published by Elsevier Science B.V.
