Scalar Field Theories with Screening Mechanisms
... dynamically suppresses theses forces without the need for fine tuning. This relies on the presence of non-linearities in the equations of motion. Most physics done is linear, so studying screening mechanisms can give insight into non-linear theories. The screening mechanism can also be relevant in t ...
