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 d-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 as the manifold. Because the T-duality swaps the torus and the dual one, one can see the manifest T-duality structure in Double Field Theory.

Quantum Information

A mysterious feature of quantum physics is that one cannot both have an absolute prediction of position and momentum. An intuitive way to understand this feature is to introduce the hidden variables in quantum theory. However, the local hidden variables are incompatible with an experimental result of Bell's inequality in a 2-qubit system. This result successfully establishes the role of quantum physics. The quantum generalization of Bell's inequality leads to a connection between entanglement entropy and the maximum violation of Bell's inequality in an arbitrary 2-qubit system. Therefore, the maximum violation of Bell's inequality indicates a non-trivial link to Quantum Entanglement. 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

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: For any compact gauge group, a non-trivial quantum Yang-Mills theory has a positive
