On Stable Pair Potentials with an Attractive Tail, Remarks on Two Papers by A. G. Basuev
Communications in Mathematical Physics(2015)
摘要
We revisit two old and apparently little known papers by Basuev (Teoret Mat Fiz 37(1):130–134, 1978 , Teoret Mat Fiz 39(1):94–105, 1979 ) and show that the results contained there yield strong improvements on current lower bounds of the convergence radius of the Mayer series for continuous particle systems interacting via a very large class of stable and tempered potentials, which includes the Lennard-Jones type potentials. In particular we analyze the case of the classical Lennard-Jones gas under the light of the Basuev scheme and, using also some new results (Yuhjtman in J Stat Phys 160(6): 1684–1695, 2015 ) on this model recently obtained by one of us, we provide a new lower bound for the Mayer series convergence radius of the classical Lennard-Jones gas, which improves by a factor of the order 10 5 on the current best lower bound recently obtained in de Lima and Procacci (J Stat Phys 157(3):422–435, 2014 ).
