Thermodynamic Properties of the Dunkl-Pauli Oscillator in an Aharonov-Bohm Flux

Abstract: We investigate the thermodynamic properties of a spin-$\frac{1}{2}$ particle described by the Dunkl-deformed Pauli equation in two dimensions in the presence of an Aharonov--Bohm (AB) flux. By replacing the standard momentum operators with Dunkl operators, the Hamiltonian incorporates reflection symmetry together with topological gauge effects. The magnetic flux imposes symmetry constraints on the Dunkl parameters, $ν_1 + \varepsilon ν_2 = 0$, linking the reflection sectors ($\varepsilon = \pm 1$) to the structure of the energy spectrum. Using the exact spectrum, we construct the canonical partition function and derive the thermodynamic quantities including the internal energy, entropy, and heat capacity. The results show that the interplay between Dunkl reflection symmetry and the AB phase leads to distinctive thermal behavior. In particular, the heat capacity exhibits a Schottky-type anomaly controlled by the magnetic flux, while at high temperatures the system approaches the classical oscillator limit.
