Web7 de nov. de 2024 · Bose-Einstein condensation is not a quantum phase transition. Quantum phase transitions occur only at zero temperature, and become crossovers for any T ≠ 0. In the same way that the paramagnetic-ferromagnetic Ising transition only occurs at zero external field, and becomes a crossover for any H ≠ 0.
