String Theory, Field Theory, and Quantum Gravity

Piljin Yi works on superstring theories, field theories, and quantum aspects of gravitational theories. He is an expert on semiclassical solitons and quantum coherent objects, and authored a series of papers on magnetic monopoles and the supersymmetric spectra of dyons in Yang-Mills theories, which remain among the authoritative references on the subject.

He is widely recognized for having given an existence proof of D0-brane bound states; this proof is one of the central evidences for the hypothetical M-theory, which, as was initially conjectured by E. Witten, is supposed to include all known superstring theories as special limits. Emergence of stable fundamental strings as coherent objects in an unstable open string theories is another of his important discoveries, with far-reaching yet unrealized implications for the illusive string field theory.

His more recent interest include a holographic picture of QCD with emphasis on nucleon dynamics, a general formulation of wall-crossing phenomena of BPS objects, and applications of superstring theory to real world phenomenology.
