Reflection Vectors and Quantum Cohomology of Blowups

Kavli Affiliate: Todor Milanov | First 5 Authors: Todor Milanov, Xiaokun Xia, , , | Summary: Let $X$ be a smooth projective variety with a semisimple quantum cohomology. It is known that the blowup $operatorname{Bl}_{rm pt}(X)$ of $X$ at one point also has semisimple quantum cohomology. In particular, the monodromy group of the quantum cohomology […]

Classification of chiral fermionic CFTs of central charge $le 16$

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Philip Boyle Smith, Ying-Hsuan Lin, Yuji Tachikawa, Yunqin Zheng, | Summary: We classify two-dimensional purely chiral conformal field theories which are defined on two-dimensional surfaces equipped with spin structure and have central charge less than or equal to 16, and discuss their duality webs. This result can […]

A diffuse scattering model of ultracold neutrons on wavy surfaces

Kavli Affiliate: T. Higuchi | First 5 Authors: S. Imajo, H. Akatsuka, K. Hatanaka, T. Higuchi, G. Ichikawa | Summary: Metal tubes plated with nickel-phosphorus are used in many fundamental physics experiments using ultracold neutrons (UCN) because of their ease of fabrication. These tubes are usually polished to a average roughness of 25-150 nm. However, […]

Constraint on Early Dark Energy from Isotropic Cosmic Birefringence

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Johannes R. Eskilt, Laura Herold, Eiichiro Komatsu, Kai Murai, Toshiya Namikawa | Summary: Polarization of the cosmic microwave background (CMB) is sensitive to new physics violating parity symmetry, such as the presence of a pseudoscalar "axionlike" field. Such a field may be responsible for early dark energy […]
