One loop amplitude from null string
Ming Yu, Chi Zhang, Yao-Zhong Zhang
We generalize the CHY formalism to one-loop level, based on the framework of the null string theory. The null string, a tensionless string theory, produces the same results as the…
Supersymmetric Hamiltonian Approach to Edge Excitations in Fractional Quantum Hall Effect
Ming Yu, Xin Zhang
A supersymmetric Hamiltonian is constructed for the edge excitations of the Moore-Read (Pfaffian) like state, which is a realization of the N=2 supersymmetric CS model. Fermionic g…
Superconformal Algebras in Light-cone Gauge Quantization of String Theories on $AdS_3
Jian Jing, Ming Yu
Motivated by superstring theories on , we construct spacetime superconformal algebras (SCAs) living on the boundary in terms of the transversal physical degrees of f…
Light-Cone Gauge Quantization of String Theories on Space
Ming Yu, Bo Zhang
Light-cone gauge quantization procedures are given, for superstring theory on space charged with NS-NS background, both in NSR and GS formalism. The spacetime (super)confor…
Fusion, Crossing and Monodromy in Conformal Field Theory Based on Current Algebra with Fractional Level
J. L. Petersen, J. Rasmussen, M. Yu
Based on our earlier work on free field realizations of conformal blocks for conformal field theories with current algebra and with fractional level and spins, we discuss i…
Conformal blocks for admissible representations of current algebra
J. L. Petersen, J. Rasmussen, M. Yu
A review is presented of the recently obtained expressions for conformal blocks for {\it admissible} representations in current algebra based on the Wakimoto free field con…
