This value is obtained when computing the occupancy number for the ground state of a Bose-Einstein condensate, and classical calculations of electron self-energies also yield this value.
In tokamaks in which a separatrix exists, the safety factor obtains this value at the separatrix. By analyzing the two-dimensional Ising model, Kramers and Wannier established that the specific heat took on this value at the Curie point. This value is obtained when computing the occupancy number for the ground state of a Bose-Einstein condensate, and classical calculations of electron self-energies also yield this value. In quantum field theory, terms having this value are removed through the process of renormalization, and this value is also obtained for the energy radiated by a black body when extrapolating the Rayleigh-Jeans law to higher frequencies. For 10 points, identify this value attained by the classical metric of general relativity at the singularity of a black hole, in which things get unquantifiably large.
