几年前,Fendley发现了具有特定F项的二维N=2超对称理论的热力学Bethe Answer(TBA)方程的显式解。受此启发,我们寻求明确的解决方案,利用其他超潜力的情况下,从ODE/IM对应的想法。我们发现,TBA方程,对应于更广泛的一类超势,承认解决方案的基本功能,如修改贝塞尔函数和合流超几何级数。
Some years ago, Fendley found an explicit solution to Thermodynamic Bethe Ansatz (TBA) equation for a N=2 supersymmetric theory in 2D with a specific F-term. Motivated by this, we seek for explicit solutions for other super-potential cases utilizing the idea from the ODE/IM correspondence. We find that TBA equations, corresponding to a wider class of super-potentials, admit solutions in terms of elementary functions such as modified Bessel functions and confluent hyper-geometric series.
