Large- limit of the gradient flow in the 2D nonlinear sigma model
Hiroki Makino, Fumihiko Sugino, Hiroshi Suzuki
The gradient flow equation in the 2D nonlinear sigma model with lattice regularization is solved in the leading order of the expansion. By using this solution, we anal…
A new mechanism of realizing inflationary universe with recourse to backreaction of quantized free fields -- Inflation without inflaton --
Yoshinobu Habara, Hikaru Kawai, Masao Ninomiya
It is shown that the inflationary era in early universe is realized due to the effect of backreaction of quantized matter fields. In fact we start by quantizing a free scalar field…
On the continuity of the commutative limit of the 4d N=4 non-commutative super Yang-Mills theory
Masanori Hanada, Hidehiko Shimada
We study the commutative limit of the non-commutative maximally supersymmetric Yang-Mills theory in four dimensions (N=4 SYM). The commutative limits of non-commutative spaces are…
Nonstandard representations of type C affine Hecke algebra from K-operators
Kohei Motegi
We construct nonstandard finite-dimensional representations of type C affine Hecke algebra from the viewpoint of quantum integrable models. There exists two classes of nonstandard…
Tracy-Widom distribution as instanton sum of 2D IIA superstrings
Shinsuke M. Nishigaki, Fumihiko Sugino
We present an analytic expression of the nonperturbative free energy of a double-well supersymmetric matrix model in its double scaling limit, which corresponds to two-dimensional…
Thermal property in Brownian motion of a particle coupled to vacuum fluctuations
Naritaka Oshita, Kazuhiro Yamamoto, Sen Zhang
We investigate Brownian motions of a particle coupled to vacuum fluctuations of a quantum field. The Unruh effect predicts that an observer in an accelerated motion sees the Minkow…
