The Schwinger pair production rate in confining theories via holography
Daisuke Kawai, Yoshiki Sato, Kentaroh Yoshida
We study the Schwinger pair production in confining theories. The production rate in an external electric field E is numerically evaluated by using the holographic description. The…
A deformation of quantum affine algebra in squashed WZNW models
Io Kawaguchi, Kentaroh Yoshida
We proceed to study infinite-dimensional symmetries in two-dimensional squashed Wess-Zumino-Novikov-Witten (WZNW) models at the classical level. The target space is given by squash…
Universal aspects of holographic Schwinger effect in general backgrounds
Yoshiki Sato, Kentaroh Yoshida
We consider universal aspects of a holographic Schwinger effect in general backgrounds with an external homogeneous electric field. The argument is based on the potential analysis…
Dynamical F-strings intersecting D2-branes in type IIA supergravity
Kunihito Uzawa, Kentaroh Yoshida
We present time-dependent exact solutions composed of F-strings intersecting D2-branes in type IIA supergravity. The F-strings tend to approach each other with time in the six-dime…
Schrodinger Sigma Models and Jordanian Twists
Io Kawaguchi, Takuya Matsumoto, Kentaroh Yoshida
We proceed to study the integrable structures of two-dimensional non-linear sigma models defined on three-dimensional Schrodinger spacetimes. We show that anisotropic Lax pairs are…
Holographic Schwinger effect in confining phase
Yoshiki Sato, Kentaroh Yoshida
We consider the Schwinger effect in confining phase by using a holographic setup. The potential analysis is performed for the confining D3-brane and D4-brane backgrounds. We find t…
