Renormalization in Quantum Statistics of Systems with Spontaneous Symmetry Breaking
Renormalization in quantum statistics in the presence of a charge associated to a spontaneously broken symmetry is discussed for the scalar field model. In contrast with the case of non-broken symmetry, the renormalization mass counter term δm depends on the chemical potential. We argue that this is connected to the ill-defined character of the charge operator. 1 Permanent address: Grupo de Fis...
متن کاملSpontaneous symmetry breaking in quantum mechanics
We present a mathematically simple procedure to explain spontaneous symmetry breaking in quantum systems. The procedure is applicable to a wide range of models and can be easily used to explain the existence of a symmetry broken state in crystals, antiferromagnets, and even superconductors. It has the advantage that it automatically brings to the fore the main players in spontaneous symmetry br...
متن کاملQuantum measurement driven by spontaneous symmetry breaking
The measurement process in quantum mechanics is usually described by the von Neumann projection postulate, which forms a basic constituent of the laws of quantum mechanics. Since this postulate requires the outside observer of the system, it is hard to apply quantum mechanics to the whole Universe. Therefore we propose that the quantum measurement process is actually a physical process associat...
متن کاملSpontaneous Symmetry Breaking in Twisted Noncommutative Quantum Theories
We analyse aspects of symmetry breaking in Moyal spacetimes within a quantisation which preserves twisted Poincaré symmetry. We point out novel features that emerge in the standard model in this formalism.
متن کاملTunneling in quantum field theory with spontaneous symmetry breaking
Tunneling in quantum field theory is well understood in the case of a single scalar field. However, in theories with spontaneous symmetry breaking, one has to take into account the additional zero modes which appear due to the Goldstone phenomenon. We calculate the false vacuum decay rate in this case. The result may differ significantly from the tunneling rates in the absence of symmetry break...
