Tautological stable pair invariants of Calabi-Yau 4-folds

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Yukinobu Toda, , , | Summary: Let $X$ be a Calabi-Yau 4-fold and $D$ a smooth divisor on it. We consider tautological complex associated with $L=mathcal{O}_X(D)$ on the moduli space of Le Potier stable pairs and define its counting invariant by integrating the Euler class […]

Sign of hard X-ray pulsation from the gamma-ray binary system LS 5039

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hiroki Yoneda, Kazuo Makishima, Teruaki Enoto, Dmitry Khangulyan, Takahiro Matsumoto | Summary: To understand the nature of the brightest gamma-ray binary system LS 5039, hard X-ray data of the object, taken with the Suzaku and NuSTAR observatories in 2007 and 2016, respectively, were analyzed. The two data […]

2, 12, 117, 1959, 45171, 1170086, …: A Hilbert series for the QCD chiral Lagrangian

Kavli Affiliate: Tom Melia | First 5 Authors: Lukas Graf, Brian Henning, Xiaochuan Lu, Tom Melia, Hitoshi Murayama | Summary: We apply Hilbert series techniques to the enumeration of operators in the mesonic QCD chiral Lagrangian. Existing Hilbert series technologies for non-linear realizations are extended to incorporate the external fields. The action of charge conjugation […]

Multi-field dark energy: cosmic acceleration on a steep potential

Kavli Affiliate: Misao Sasaki | First 5 Authors: Yashar Akrami, Misao Sasaki, Adam R. Solomon, Valeri Vardanyan, | Summary: We argue that dark energy with multiple fields is theoretically well-motivated and predicts distinct observational signatures, in particular when cosmic acceleration takes place along a trajectory that is highly non-geodesic in field space. Such models provide […]

Quiver Yangian and Supersymmetric Quantum Mechanics

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Dmitry Galakhov, Masahito Yamazaki, , , | Summary: The statistical model of crystal melting represents BPS configurations of D-branes on a toric Calabi-Yau three-fold. Recently it has been noticed that an infinite-dimensional algebra, the quiver Yangian, acts consistently on the crystal-melting configurations. We physically derive the algebra […]
