| Popis: | We study a large class of models of two-dimensional quantum lattice systems with continuous symmetries, and we prove a general McBryan–Spencer–Koma–Tasaki theorem concerning algebraic decay of correlations. We present applications of our main result to the Heisenberg, Hubbard, and t-J models, and to certain models of random loops. Annales Henri Poincaré, 18 (9) ISSN:1424-0661 ISSN:1424-0637 |
