Non-Gaussianity of Entanglement Entropy and Correlations of Composite Operators
Satoshi Iso, Takato Mori, Katsuta Sakai
This is an extended version of the previous paper arXiv:2103.05303 to study entanglement entropy (EE) of a half space in interacting field theories. In the previous paper, we have…
Wilsonian Effective Action and Entanglement Entropy
Satoshi Iso, Takato Mori, Katsuta Sakai
This is a continuation of our previous works on entanglement entropy (EE) in interacting field theories. In arXiv:2103.05303, we have proposed the notion of gauge th…
Burgers Equation vs. Large Limit in -deformed Vector Model
Junichi Haruna, Katsuta Sakai, Kentaroh Yoshida
We study a -deformed vector model, which is classically equivalent to the Nambu-Goto action with static gauge. The thermal free energy density can be computed exac…
Entanglement entropy in scalar field theory and gauge theory on Feynman diagrams
Satoshi Iso, Takato Mori, Katsuta Sakai
Entanglement entropy (EE) in interacting field theories has two important issues: renormalization of UV divergences and non-Gaussianity of the vacuum. In this letter, we investigat…
Large N Analysis of -deformation and Unavoidable Negative-norm States
Junichi Haruna, Takaaki Ishii, Hikaru Kawai +2
We study non-perturbative quantum aspects of -deformation of a free vector model by employing the large limit. It is shown that bound states of the original fi…
A note on higher spin symmetry in the IIB matrix model with the operator interpretation
Katsuta Sakai
We study the IIB matrix model in an interpretation where the matrices are differential operators defined on curved spacetimes. In this interpretation, coefficients of higher deriva…
