Entanglement and Quantum Phases in the Anisotropic Ferromagnetic Heisenberg Chain in the Presence of Domain Walls

F. C. Alcaraz, A. Saguia, M. S. Sarandy

We discuss entanglement in the spin-1/2 anisotropic ferromagnetic Heisenberg chain in the presence of a boundary magnetic field generating domain walls. By increasing the magnetic…

Dynamical gluon mass generation from <A^2> in linear covariant gauges

D. Dudal, H. Verschelde, J. A. Gracey +4

We construct the multiplicatively renormalizable effective potential for the mass dimension two local composite operator A^2 in linear covariant gauges. We show that the formation…

The anomalous dimension of the gluon-ghost mass operator in Yang-Mills theory

D. Dudal, H. Verschelde, V. E. R. Lemes +5

The local composite gluon-ghost operator is analysed in the framework of the algebraic renormalization in SU(N) Yang-Mills theories in the…

More on ghost condensation in Yang-Mills theory: BCS versus Overhauser effect and the breakdown of the Nakanishi-Ojima annex SL(2,R) symmetry

D. Dudal, H. Verschelde, V. E. R. Lemes +5

We analyze the ghost condensates <f^{abc}c^{b}c^{c}>, <f^{abc}\oc^{b}\oc^{c}> and <f^{abc}\oc^{b}c^{c}> in Yang-Mills theory in the Curci-Ferrari gauge. By combining the local comp…

Vacuum Condensates of Dimension Two in Pure Euclidean Yang-Mills

D. Dudal, A. R. Fazio, V. E. R. Lemes +4

Gluon and ghost condensates of dimension two and their relevance for Yang-Mills theories are briefly reviewed

Gluon-ghost condensate of mass dimension 2 in the Curci-Ferrari gauge

D. Dudal, H. Verschelde, V. E. R. Lemes +3

The effective potential for an on-shell BRST invariant gluon-ghost condensate of mass dimension 2 in the Curci-Ferrari gauge in SU(N) Yang-Mills is analysed by combining the local…
