Quadratic differentials as stability conditions
We prove that moduli spaces of meromorphic quadratic differentials with
simple zeroes on compact Riemann surfaces can be identified with spaces of
stability conditions on a class of CY3 triangulated categories defined using
quivers with potential associated to triangulated surfaces. We relate the
finite-length trajectories of such quadratic differentials to the stable
objects of the corresponding stability condition.Comment: 123 pages; 38 figures. Version 2: hypotheses in the main results

Electric dipole moments and the search for new physics
Static electric dipole moments of nondegenerate systems probe mass scales for
physics beyond the Standard Model well beyond those reached directly at high
energy colliders. Discrimination between different physics models, however,
requires complementary searches in atomic-molecular-and-optical, nuclear and
particle physics. In this report, we discuss the current status and prospects
in the near future for a compelling suite of such experiments, along with
developments needed in the encompassing theoretical framework.Comment: Contribution to Snowmass 2021; updated with community edits and

De Novo Domestication Concept for Potato Germplasm Enhancement
Wild potato germplasm serves as a natural pool of agronomically valuable traits for potato breeding, such as resistance to pathogens and abiotic stresses, quality, and consumer-oriented traits. The introgression of these traits into cultivated potato is hampered by the different kinds of incompatibility and linkages between desirable and undesirable features in hybrid progeny. The trait donor improvement via correction of negative characteristics prior to hybridization to domestic potato can be a solution to the linkage drag problem. The de novo domestication concept for developing new crops using gene editing technologies was previously proposed and performed for tomato and physalis. In this review, we collected information about donor properties of different wild potato species and developed a strategy for potato germplasm enhancement using the de novo domestication approach. The possible modifications of several candidate genes responsible for undesirable traits in wild potato, including high steroidal glycoalkaloid content, self-incompatibility, tuberization under short day conditions, and long stolons are proposed. The current challenges and future prospects of implementing the de novo domestication strategy for potato are discussed
