Multi-field inflation and preheating in asymmetric -attractors
Oksana Iarygina, Evangelos I. Sfakianakis, Dong-Gang Wang +1
We analyze and compare the multi-field dynamics during inflation and preheating in symmetric and asymmetric models of -attractors, characterized by a hyperbolic field-space mani…
Shift-Symmetric Orbital Inflation: single field or multi-field?
Ana Achúcarro, Edmund J. Copeland, Oksana Iarygina +3
We present a new class of two-field inflationary attractor models, known as `shift-symmetric orbital inflation', whose behaviour is strongly multi-field but whose predictions are r…
Universality and scaling in multi-field -attractor preheating
Oksana Iarygina, Evangelos I. Sfakianakis, Dong-Gang Wang +1
We explore preheating in multi-field models of inflation in which the field-space metric is a highly curved hyperbolic manifold. One broad family of such models is called -attra…
