Nonperturbative studies of supersymmetric matrix quantum mechanics with 4 and 8 supercharges at finite temperature

Understand

We investigate thermodynamic properties of one-dimensional U(N) supersymmetric gauge theories with 4 and 8 supercharges in the planar large-N limit by Monte Carlo calculations.

• Unlike the 16 supercharge case, the threshold bound state with zero energy is widely believed not to exist in these models.
• This led A.V.
• Smilga to conjecture that the internal energy decreases exponentially at low temperature instead of decreasing with a power law.
