I give a review (, possibly biased, ) on chiral theory as edge modes from a personal point of view. After reviewing the problem of chiral theory on the lattice, I comment on the standard method by symmetric mass generation of mirror fermion.I also review the recent work on chiral boson theory in 1+1 d by M. DeMarco, E. Lake, X.-G. Wen.
Since the establishment of the Standard Model of elementary particles, the research in quantum field theory has investigated non-perturbative analysis based on theories with high symmetry, such as supersymmetry. However, the Standard Model, including QCD, has relatively low symmetry, and it is getting important to analyze theories based on features appearing only in QFT with low symmetry. In...
In this talk, we will discuss possible holographic dual of de Sitter Space from two different ideas. One is the original dS/CFT correspondence, and we will present an explicit CFT dual for three dimensional de Sitter space and examine its properties. The other is to study a holographic dual of a half de Sitter space, which has a time- like boundary. After we explain the results based on these...
We study the properties of the Petz recovery map in chaotic systems, such as the Hayden-Preskill setup for evaporating black holes and the SYK model. Since these systems exhibit the phenomenon called scrambling, we expect that the expression of the recovery channel $\mathcal{R}$ gets simplified, given by just the adjoint $\mathcal{N}^{\dagger}$ of the original channel $\mathcal{N}$ which...
Wilson's exact renormalization group (ERG) is a fundamental idea for defining quantum field theory at a non-perturbative level. The conventional ERG based on the momentum cutoff, however, cannot preserve the manifest gauge invariance and this fact hinders non-perturbative analyses of gauge theories using ERG. In this talk, I explain the gradient flow exact renormalization group (GFERG), which...
Current problems in quantum gravity and string theory will be summarized and how they may be overcome in the future will be discussed.
