Runaway Gravitational Production of Dark Photons

Posted by Chicago

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: We demonstrate that gravitational particle production (GPP) of a massive, Abelian, vector (Proca) field during inflation in the presence of nonminimal coupling to gravity may suffer from an instability which leads to runaway production of […]

K-theoretic Heisenberg algebras and permutation-equivariant Gromov–Witten theory

Posted by dbos Tokyo

Kavli Affiliate: Todor Milanov | First 5 Authors: Todor Milanov, , , , | Summary: We found an interesting application of the K-theoretic Heisenberg algebras of Weiqiang Wang to the foundations of permutation equivariant K-theoretic Gromov–Witten theory. We also found an explicit formula for the genus 0 correlators in the permutation equivariant Gromov–Witten theory of […]
