Sine-Gordon Equation and Quantum spin transport in one-dimension
博士 === 國立臺灣大學 === 物理研究所 === 97 === We studied the spin transport mechanism in a S=1/2 antiferromagnetic chain. The spin chain is mapped into a fermion system, where equation of motion is transformed into a (Double) Sine-Gordon Equation ((D)SGE) with the approach of bosonization. We studied first, th...
