Coherent Topological Charge Structure in Models and QCD
Saeed Ahmad, Jonathan T. Lenaghan, H. B. Thacker
In an effort to clarify the significance of the recent observation of long-range topological charge coherence in QCD gauge configurations, we study the local topological charge dis…
Deconfinement in Matrix Models about the Gross--Witten Point
Adrian Dumitru, Jonathan Lenaghan, Robert D. Pisarski
We study the deconfining phase transition in SU(N) gauge theories at nonzero temperature using a matrix model of Polyakov loops. The most general effective action, including all te…
Topological Charge Membranes in 2D and 4D Gauge Theory
H. Thacker, S. Ahmad, J. Lenaghan
Local topological charge structure in the 2D CP(N-1) sigma models is studied using the overlap Dirac operator. Long-range coherence of topological charge along locally 1D regions i…
Fluctuation Induced Critical Behavior at Non-Zero Temperature and Chemical Potential
K. Splittorff, J. T. Lenaghan, J. Wirstam
We discuss phase transitions in relativistic systems as a function of both chemical potential and temperature. The presence of a chemical potential explicitly breaks Lorentz invari…
Melting the Diquark Condensate in Two-Color QCD: A Renormalization Group Analysis
J. Wirstam, J. T. Lenaghan, K. Splittorff
We use a Landau theory and the epsilon expansion to study the superfluid phase transition of two-color QCD at nonzero temperature, T, and baryonic chemical potential, mu. At low T,…
Saturation and Pion Production in Proton-Nucleus Collisions
J. T. Lenaghan, K. Tuominen
We study the effects of gluon saturation on pion production in high energy proton-nucleus collisions using the color glass condensate model. At high p_perp, we show that the p_perp…
