Phys. Rev. E 64, 062103 (2001) [4 pages]Thermodynamics of the asymmetric double sinh-Gordon theory in 1+1 dimensionsReceived 11 June 2001; published 26 November 2001 Classical thermodynamics of the (1+1)-dimensional asymmetric double sinh-Gordon system is investigated. The pseudo-Schrödinger equation resulting from the transfer integral method is solved numerically and within the semiclassical approximation; the exact results are also given at several temperatures. It is found that the specific heat exhibits a characteristic hump resembling a similar one observed in the systems with a symmetric potential; in some structures, extremely narrow and extremely high peak is developed. The interpretation for this behavior is given. © 2001 The American Physical Society URL:
