DOI: 10.1007/jhep10(2024)136

Abstract: Two different methods are used to study the existence and stability of the (1+1)-dimensional Φ4 oscillon. The variational technique approximates it by a periodic function with a set of adiabatically changing parameters. An alternative approach… read more here.

DOI: 10.1103/physrevd.107.085012

Abstract: Oscillons in a simple, 1-dimensional scalar field theory with a cubic potential are discussed. The theory has a classical sphaleron, whose decay generates a version of the oscillon. A good approximation to the small-amplitude oscillon… read more here.

DOI: 10.1103/physrevlett.130.181002

Abstract: In broad classes of inflationary models the period of accelerated expansion is followed by fragmentation of the inflaton scalar field into localized, long-lived, and massive oscillon excitations. We demonstrate that matter dominance of oscillons, followed… read more here.

DOI: 10.1177/10812865221107413

Abstract: The oscillon is a highly localized dynamical phenomenon occurring in a thin horizontal layer of granular material, which rests on a rigid plate oscillating in the vertical direction. The geometry is axially symmetric and physically… read more here.
