Spontaneous Symmetry BreakingEffective Field TheoriesWhen a two-dimensional harmonic potential is applied to bosonic cold atoms, the atoms become a cigar shape and the radial energy level is discretized. If the strength of the potential or the total number of atoms is tuned, the atoms can occupy...
Specifically we analyze the solution structure near a point where a path of symmetry-breaking bifurcations and a path of fold points intersect. The treatment is such that numerical information is obtained which could prove useful when switching from one path to another....
We can write these interactions after the EW symmetry breaking as the following effective Lagrangian operators:(2.21) where the associated dimensional Wilson coefficients read(2.22)⁎⁎⁎⁎⁎ in the fermion mass basis defined by(2.23) where and are unitary transformations over the left-handed...
In its simplest form, one would add one single scalar doublet to the SM, odd under a Z2 symmetry that leaves all the SM fields unchanged. If, upon spontaneous symmetry breaking, the new field does not develop a vacuum expectation value, then the Z2 symmetry remains unbroken and will be...
Emergent O(4) symmetry and order parameter of VBS Next we discuss the nature of the QSL-VBS transition and the symmetry breaking pattern of the\sqrt{12}\times \sqrt{12}phase. As explained in the Supplemental Notes, it is expected theoretically13,54that this transition is driven by the cond...

A direct method for finding the mode interaction point of a symmetry breaking Hopf bifurcation and a symmetry preserving Hopf bifurcation in problems with 2-symmetry is developed. It has been shown that the mode interaction point corresponds to an isolated solution of an extended system. The ...
