弱扰动下铁磁XXZ链的界面动力学

On the dynamics of interfaces in the ferromagnetic XXZ chain under weak perturbations

Bruno Nachtergaele, Wolfgang L Spitzer, Shannon Starr

摘要:

研究了铁磁XXZ链在磁场中界面的时间演化。引入了一个标度极限,其中磁场的强度趋于零,微观时间趋于无穷大,同时保持它们的乘积恒定。的领先项和它的第一个修正的确定和进一步分析的情况下,一个均匀的磁场更详细。

英文摘要:

We study the time evolution of interfaces of the ferromagnetic XXZ chain in a magnetic field. A scaling limit is introduced where the strength of the magnetic field tends to zero and the microscopic time to infinity while keeping their product constant. The leading term and its first correction are determined and further analyzed in more detail for the case of a uniform magnetic field.
