Lee-Yang Zeros And Particle Fluctuations
Mohamed El Hedi Bahri, Ian Jauslin, Joel L. Lebowitz
The paper proves that if Lee–Yang zeros of the grand‑canonical partition function stay away from a positive real fugacity, then in the thermodynamic limit the pressure and its deri…

Convergent Power Series for Anharmonic Chain with Periodic Forcing
Pedro L. Garrido, Tomasz Komorowski, Joel L. Lebowitz +1
We study the propagation of energy in one-dimensional anharmonic chains subject to a periodic, localized forcing. For the purely harmonic case, forcing frequencies outside the line…
