FUTURE PROJECTS

String Theory

Double Field Theory is a proposal to incorporate T-duality as a symmetry structure of a field theory on a 2d-dimensional doubled torus. When String Theory on a $-dimensional torus, the symmetry group is isomorphic to the orthogonal group O(d, d; Z). Double Field Theory has the additional dual torus. Hence Double Field Theory provides a doubled geometry. One can see the manifest T-duality structure in Double Field Theory.

Quantum Information

Many studies in Quantum Entanglement were derivable based on numerical approaches. Therefore, people are interested in developing new technology for obtaining analytical solutions. Recently, the Ryu-Takayanagi prescription in the Anti-de Sitter (AdS) spacetime simplifies the computation. The procedure is to solve a co-dimensional two surface with a minimized area and a given boundary coming from one lower-dimensional Conformal Field Theory (CFT). This result implies that emergent spacetime comes from the degrees of Quantum Entanglement. Although the conformal symmetry has largely constrained possible analytical solutions, the n-sheet method (replica trick) could not have a convenient application. Developing methods beyond or without the replica trick in the AdS/CFT correspondence has received much attention in the study of Quantum Information.

Quantum Field Theory and Lattice Theory

Applying the perturbation method to QFT builds a generic tool for a probe of a weakly coupled region. Although people still do not know how to study a strongly coupled region from a similar procedure, various physical phenomena and experiments confirmed the perturbation method. The most interesting strongly coupled system should be Quantum Chromodynamics (QCD). QCD describes the dynamics between quarks and gluons. The color confinement and asymptotic freedom are open questions. The difficulty is the extraction of physical information from the low-energy QCD. The numerical study is also time-consuming due to a strong constraint of the Nielsen-Ninomiya theorem. The low-energy (or strong coupling) regime is necessary to develop new numerical and analytical tools because the coupling is strong. This direction address an unsolved problem in mathematical physics, the Yang-Mills existence and mass gap problem.
