Analytical methods of asymmetry double sine-Gordon equation in infinite one-dimensional system
Nan-Hong Kuo, C. D. Hu
Traditionally, Double Sine-Gordon Equation (DSGE) is seen as a nonintegrable equation. That means we cannot find general solutions in asymmetry DSGE. In this paper, we develop anal…
A study of solutions of the combined sine cosine Gordon equation
Nan-Hong Kuo, C. D. Hu
We have studied the solutions of the combined sine-cosine-Gordon Equation found by Wazwaz (App. Math. Comp. 177, 755 (2006)) using the variable separated ODE method. These solution…
Solitons and spin transport in an antiferromagnetic spin chain
Nan-Hong Kuo, Sujit Sarkar, C. D. Hu
We study the spin transport on a S=1/2 antiferromagnetic chain with external fields which provids a phase angle. The equation of motion becomes the sine-Gordon equation after Jorda…

Nan-Hong Kuo, Sujit Sarkar, C. D. Hu
We present solutions of asymmetric double sine-Gordon equation (DSGE) of an infinite system based on Mobius transformation and numerical exercise. This method is able to give the f…
Quantum spin pump on a finite antiferromagnetic chain through bulk states
Nan-Hong Kuo, Sujit Sarkar, C. D. Hu
We studied the possibility of the spin pump in a S=1/2 antiferromagnetic chain. The spin chain is mapped into a fermion system and bosonization is utilized to transform the equatio…
