Contribution

It presents a novel method for analyzing oscillons and demonstrates how changing the minimum field value affects their dynamics and structure.

Findings

Changing the minimum field value leads to oscillon pairs with different amplitudes and frequencies.

Analytical results closely match numerical simulations.

The approach provides new insights into oscillon behavior in scalar field theories.

Abstract

In this work we study configurations in one-dimensional scalar field theory, which are time-dependent, localized in space and extremely long-lived called oscillons. It is investigated how the action of changing the minimum value of the field configuration representing the oscillon affects its behavior. We find that one of the consequences of this procedure, is the appearance of a pair of oscillon-like structures presenting different amplitudes and frequencies of oscillation. We also compare our analytical results to numerical ones, showing excellent agreement.
