WebApr 11, 2024 · A string field theory for closed bosonic strings is formulated using pants decomposition and the Fokker–Planck formalism. String theory is a framework where elementary particles and their interactions are replaced with strings as the basic building blocks of matter. Webt. e. In physics, topological order [1] is a kind of order in the zero-temperature phase of matter (also known as quantum matter). Macroscopically, topological order is defined and described by robust ground state degeneracy [2] and quantized non-Abelian geometric phases of degenerate ground states. [1] Microscopically, topological orders ...
