New limits on anomalous contributions to the vertex

J. L. Birman, F. Déliot, M. C. N. Fiolhais +2

The latest and most precise top quark measurements at the LHC and Tevatron are used to establish new limits on the vertex. Recent results on the measurements of the -boson…

Size Effects in the Ginzburg-Landau Theory

Miguel C. N. Fiolhais, Joseph L. Birman

The Ginzburg-Landau theory is analyzed in the case of small dimension superconductors, a couple of orders of magnitude above the coherence length, where the theory is still valid b…

Gauge Invariance and Spontaneous Symmetry Breaking in Two-Gap Superconductors

Miguel C. N. Fiolhais, Joseph L. Birman

The gauge symmetry of the Ginzburg-Landau theory for two-gap superconductors is analyzed in this letter. We argue that the existence of two different phases, associated with the tw…

Phenomenological correlations in high-temperature superconductors

Miguel C. N. Fiolhais, Joseph L. Birman

An interpretation of the quadratic parameter of the Ginzburg-Landau theory of superconductivity is presented in this paper. The negative term in the potential, which allows the spo…

Decomposition of direct product at an arbitrary Brillouin zone point:

Jian Li, Jiufeng J. Tu, Joseph L. Birman

A general rule is presented for the decomposition of the direct product of irreducible representation at arbitrary Brillouin zone point with its negative: the number of th…

One dimensional zone center phonons in space group

Jian Li, Jiufeng J. Tu, Joseph L. Birman

Motivated by experiments, we performed a systematic study on the one dimensional zone center phonons in space groups. All the one dimensional phonon modes for different Wyc…
