    "abstract": "The Casimir force has its origin in finite modification of the infinite\nzero-point energy induced by a specific boundary condition for the spatial\nconfiguration. In terms of the imaginary-time formalism at finite temperature,\nthe root of Planck\u0027s law of radiation can be traced back to finite modification\nof the infinite vacuum energy induced by the periodic boundary condition in the\ntemporal direction. We give the explicit conversion from the Casimir force to\nPlanck\u0027s law of radiation, which shows the apparent correspondence between the\nsystem bounded by parallel conducting plates and the thermodynamic system. The\ntemperature inversion symmetry and the duality relation in the thermodynamics\nare also discussed. We conclude that the effective temperature characterized by\nthe spatial extension should no longer be regarded as genuine temperature.",
