Supersymmetric QFT, Super Loop Spaces and Bismut-Chern Character
Fei Han
In this paper, we give a quantum interpretation of the Bismut-Chern character form (the loop space lifting of the Chern character form) as well as the Chern character form associat…

Witten Genus and String Complete Intersections
Qingtao Chen, Fei Han
In this note, we prove that the Witten genus of nonsingular string complete intersections in product of complex projective spaces vanishes. Our result generalizes a known result of…

Modular invariance, characteristic numbers and invariants
Fei Han, Weiping Zhang
We generalize the "miraculous cancellation" formulas of Alvarez-Gaumé, Witten and Kefeng Liu to a twisted version where an extra complex line bundle is involved. We also apply our…
