Universal Confining Strings: From Compact QED to the Hadron Spectrum

M. C. Diamantini, F. Quevedo, C. A. Trugenberger +1

We investigate the description of quark confinement in terms of confining strings or flux tubes. We show that compact QED with a topological -term, in the dyon condensation pha…

Bose metals, from prediction to realization

M. Cristina Diamantini, Carlo A. Trugenberger

Bose metals are metals made of Cooper pairs, which form at very low temperatures in superconducting films and Josephson junction arrays as an intermediate phase between superconduc…

Bulk superinsulation and polar nematic order in nanopatterned NbTiN

A. Yu. Mironov, C. A. Trugenberger, M. C. Diamantini +2

We present an experimental evidence of 3D superinsulation in a nanopatterned slab of NbTiN, given by the Vogel-Fulcher-Tamman (VFT) scaling of the conductance when approaching the…

Dark matter and dark energy in combinatorial quantum gravity

Carlo A. Trugenberger

We point out that dark matter and dark energy arise naturally in a recently proposed model of combinatorial quantum gravity. Dark energy is due to the ground-state curvature at fin…

Topological gauge theory of vortices in type-III superconductors

M. C. Diamantini, C. A. Trugenberger, V. M. Vinokur

Traditional superconductors fall into two categories, type-I, expelling magnetic fields, and type-II, into which magnetic fields exceeding a lower critical field penet…
