Soft Oscillons
Fabio van Dissel, Oriol Pujolàs
We present a novel type of soliton dubbed soft oscillons. In contrast with conventional oscillons the soft counterparts come in a continuum of unboundedly large sizes. They are pec…
Semiclassical Backreaction: A Qualitative Assessment
Fabio van Dissel, George Zahariade
The backreaction of quantum degrees of freedom on classical backgrounds is a poorly understood topic in theoretical physics. Most often it is treated within the semiclassical appro…
Oscillon spectroscopy
Fabio van Dissel, Oriol Pujolas, Evangelos Sfakianakis
The sine-Gordon model in 3+1 dimensions is known to admit two oscillons of different energy and frequency but comparable lifetime. We show that the oscillon spectrum includes more…
Symmetric multifield oscillons
Fabio van Dissel, Evangelos I. Sfakianakis
Oscillons are long-lived, spatially localized field configurations, which are supported by attractive non-linearities in the scalar potential. We study oscillons comprised of multi…
