We propose $D$ mesons as probes to investigate finite-volume effects for chiral symmetry breaking at zero and finite temperatures. By using the $2+1$-flavor linear sigma model with constituent light quarks, we analyze the Casimir effects for the $\ensuremath{\sigma}$ mean fields; the chiral symmetry is rapidly restored by the antiperiodic boundary for light quarks, and the chiral symmetry breaking is catalyzed by the periodic boundary. We also show the phase diagram of the $\ensuremath{\sigma… Expand

Casimir effect for lattice fermions
Abstract We propose a definition of the Casimir energy for free lattice fermions. From this definition, we study the Casimir effects for the massless or massive naive fermion, Wilson fermion, andExpand
