New Non-supersymmetric Tachyon-Free Strings
In four decades of string theory research only a handful of examples of non-supersymmetric, tachyon-free string models with only one neutral scalar at tree level are known. In this talk I will present new non-supersymmetric and tachyon-free string theories using asymmetric orbifolds that serve as the lower-dimensional counterparts to the O(16)xO(16) string in 4d, 6d, and 8d, each featuring only one neutral scalar at tree level.
