Anthropic considerations in multiple-domain theories and the scale of electroweak symmetry breaking
The standard model quality parameters quantum physical parameter values
2014/12/22
One of the puzzles of the Standard Model is why the mass parameter which determines the scale of the Weak interactions is closer to the scale of Quantum Chromodymanics (QCD) than to the Grand Unificat...
PT symmetry and spontaneous symmetry breaking in a microwave billiard
PT symmetry spontaneous symmetry microwave billiard Quantum Physics
2011/10/9
Abstract: We demonstrate the presence of parity-time (PT) symmetry for the non-Hermitian two-state Hamiltonian of a dissipative microwave billiard in the vicinity of an exceptional point (EP). The sha...

2010/12/27
We propose a conjecture about the detailed structure of the conformal symmetry breaking term in the QCD generalization of Crewther relation and demonstrate its validity at the $\alpha_s^4$-level. We c...
Universal routes to spontaneous PT-symmetry breaking in non-hermitian quantum systems
Universal routes spontaneous PT-symmetry non-hermitian quantum systems
2010/11/8
PT-symmetric systems can have a real spectrum even when their Hamiltonian is non-hermitian, but develop a complex spectrum when the degree of non-hermiticity increases. Here we utilize random-matrix t...
The implications of chiral symmetry breaking and SU(3) symmetry breaking have been studied in the chiral constituent quark model ( CQM). The role of hidden strangeness component has been investigated ...
Symmetry breaking orbital anisotropy on detwinned Ba(Fe1-xCox)2As2 above the spin density wave transition
Symmetry breaking orbital anisotropy detwinned Ba
2010/11/17
Nematicity, defined as broken rotational symmetry, has recently been observed in the competing phases in proximity to the superconducting phase in the high TC cuprates (1-2). Similarly, the new iron-b...
Competition between symmetry breaking and onset of collapse in weakly coupled atomic condensates
symmetry breaking atomic condensates
2010/4/6
We analyze the symmetry breaking of matter-wave solitons in a pair of cigar-shaped traps coupled by tunneling of atoms. The model is based on a system of linearly coupled nonpolynomial Schr\"odinger e...

Electroweak Symmetry Breaking in Low-Scale Quantum Gravity
Low-Scale Quantum Gravity electroweak symmetry breaking
2010/4/15
We discuss the implications of low-scale quantum gravity on electroweak symmetry breaking by computing one-loop gravitational corrections to the Higgs potential. We conclude that these radiative corre...
