This paper demonstrates chiral quantum heating and refrigeration by dynamically encircling a closed loop near a Liouvillian exceptional point (LEP) using a Paul-trapped ultracold ion. The experiment shows that the cycling direction is associated with chirality and heat release/absorption, with both adiabaticity breakdown and the Landau-Zener-Stückelberg process playing crucial roles. The findings contribute to understanding chiral and topological features in non-Hermitian systems and their relationship with quantum thermodynamics.
