Meson turbulence at quark deconfinement from AdS/CFT
Koji Hashimoto, Shunichiro Kinoshita, Keiju Murata +1
Based on the QCD string picture at confining phase, we conjecture that the deconfinement transition always accompanies a condensation of higher meson resonances with a power-law be…
Neutral bions in the CP^{N-1} model for resurgence
Tatsuhiro Misumi, Muneto Nitta, Norisuke Sakai
Classical configurations in the CP^{N-1} model on R^1 x S^1 is studied with twisted boundary conditions. Starting from fractional instantons with the Z_N twisted boundary condition…
Non-Abelian Sine-Gordon Solitons
Muneto Nitta
We point out that non-Abelian sine-Gordon solitons stably exist in the chiral Lagrangian. They also exist in a gauge theory with two by complex scalar fields…
Fractional instantons and bions in the O(N) model with twisted boundary conditions
Muneto Nitta
Recently, multiple fractional instanton configurations with zero instanton charge, called bions, have been revealed to play important roles in quantum field theories on compactifie…
D-brane solitons in various dimensions
Sven Bjarke Gudnason, Muneto Nitta
We construct a D-brane soliton, a composite topological soliton sharing some properties with a D-brane, in a Skyrme model in 4+1 dimensions, in which Skyrmions are strings ending o…
Exact Results in Discretized Gauge Theories
So Matsuura, Tatsuhiro Misumi, Kazutoshi Ohta
We apply the localization technique to topologically twisted N=(2,2) supersymmetric gauge theory on a discretized Riemann surface (the generalized Sugino model). We exactly evaluat…
