Thermodynamic Bethe ansatz and wall crossing for deformed supersymmetric quantum mechanics

Abstract

We study the deformed supersymmetric quantum mechanics with a polynomial superpotential with $\hslash$ correction. In the minimal chamber, where all turning points are real and distinct, it was shown that the exact Wentzel--Kramers--Brillouin periods obey the ${\mathbb{Z}}_4$-extended thermodynamic Bethe ansatz (TBA) equations of the undeformed potential. By changing the energy parameter above/below the critical points, the turning points become complex, and the moduli are outside of the minimal chamber. We study the wall crossing of the ${\mathbb{Z}}_4$-extended TBA equations by this change of moduli and show that the ${\mathbb{Z}}_4$ structure is preserved after the wall crossing. In particular, the TBA equations for the cubic superpotential are studied in detail, where there are two chambers (minimal and maximal). At the maximally symmetric point in the maximal chamber, the TBA system becomes the two sets of the $D_3$-type TBA equations, which are regarded as the ${\mathbb{Z}}_4$ extension of the $A_3/{\mathbb{Z}}_2$-type TBA equation.
