Noncommutative covering projections and $K$-homology math.KT If $X$ is a topological space then there is a natural homomorphism $\pi_1(X)\rightarrow K_1(X)$ from a fundamental group to a $K_1$-homology group. Covering projections depend of fundamental group. So $K_1$-homology groups are interrelated with covering p...

Quantum quenches and competing orders cond-mat.supr-con cond-mat.str-el hep-th We study the nonequilibrium dynamics of an electronic model of competition between an unconventional charge density wave (a bond density wave) and $d$-wave superconductivity. In a time-dependent Hartree-Fock+BCS approximation, the dynami...

The QCD improved electroweak parameter $\rho$ hep-ph In the present paper, we make a detailed analysis for the QCD corrections to the electroweak $\rho$ parameter by applying the principle of maximum conformality (PMC). As a comparison, we show that under the conventional scale setting, we have $\Delta\rho|_{\rm N^...

Synchronization of two self-excited double pendula physics.class-ph nlin.CD We consider the synchronization of two self-excited double pendula. We show that such pendula hanging on the same beam can have four different synchronous configurations. Our approximate analytical analysis allows us to derive the synchroni...

The Transport of Cosmic Rays Across Magnetic Fieldlines astro-ph.HE The long residence times and small anisotropies of cosmic rays suggest that they are well confined and well scattered by the Galactic magnetic field.

Positronium contribution to the electron g-2 hep-ph The contribution of positronium to the electron $g$-2 ($a_e$) has been computed in Ref.
