Majorana Fermion Zero Modes and Anomalies in String and M Theories
Yotaro Sato
In this thesis, we propose a new consistency condition of quantum field theory: Having an odd number of Majorana fermion zero modes on a dynamical point-like soliton signifies an i…
Direct computation of period polynomials and classification of K3-fibred Calabi--Yau threefolds
Yuichi Enoki, Yotaro Sato, Taizan Watari
One can assign to four-dimensional N=2 supersymmetric Heterotic string vacua a set of classification invariants including a lattice and vector-valued modular forms. Some of t…
On odd number of fermion zero modes on solitons in quantum field theory and string/M theory
Yotaro Sato, Yuji Tachikawa, Taizan Watari
We argue that having an odd number of Majorana fermion zero modes on a dynamical point-like soliton signifies an inconsistency in a theory with 3+1 and higher dimensions. We check…
Witten Anomaly in 4d Heterotic Compactificaitons with N = 2 Supersymmetry
Yuichi Enoki, Yotaro Sato, Taizan Watari
We showed that there is no SU(2) Witten anomaly in a large class of 4d N = 2 supersymmetric Heterotic string compactifications. The consistency conditions we consider are the modul…
