Bead, hoop and spring as a classical spontaneous symmetry breaking problem

Sonoluminescence as Spontaneous Symmetry Breaking

Although sonoluminescence was discovered in 1933, sofar the phenomenon has not been properly explained. In this paper we interpret this phenonmenon as spontaneous symmetry breaking. First, the single bubble sonoluminescence (SBSL) is considered. The mechanism here has been confirmed to be broken spherical symmetry by the work of D F Gaitan et al and Dam J S et al. In this paper we extend this t...

Classical Phase Space Structure Induced by Spontaneous Symmetry Breaking

The collective dynamics of a many-body system is described as a special case of low-energy quantum dynamics, occurring when the ground state breaks a continuous symmetry of the Hamiltonian. This approach is applied to the spontaneous breaking of the rotational symmetry of a nuclear Hamiltonian. It is shown that the excitation operator of the isovector low-lying angular oscillations in deformed ...

Nonperturbative Spontaneous Symmetry Breaking

One of the most astonishing results of quantum field theory is spontaneous symmetry breaking. One can say that it is the situation when something arises from the quantization. This means that on the quantum level one has something that was not present on the classical level. Coleman and Weinberg [1] write : “ . . . higher-order effects may qualitatively change the character of a physical theory...

Spontaneous Symmetry Breaking as a Basis of Particle Mass

Electroweak theory joins electromagnetism with the weak force in a single quantum field theory, ascribing the two fundamental interactions—so different in their manifestations—to a common symmetry principle. How the electroweak gauge symmetry is hidden is one of the most urgent and challenging questions facing particle physics. The provisional answer incorporated in the “standard model” of part...
