Fundamental interactions

We draw a picture of physical systems that allows us to recognize what
“time” is by requiring consistency with the way that time enters the
fundamental laws of Physics. Elements of the picture are two
non-interacting and yet entangled quantum systems, one of which acting
as a clock. The setting is based on the Page and Wootters mechanism,
with tools from large-N quantum approaches....

3. Scrutinizing the pion condensed phase

When the isospin chemical potential exceeds the pion mass, charged pions condense in the zero- momentum state forming a superfluid. Chiral perturbation theory provides a very powerful tool for studying this phase. However, the formalism that is usually employed in this context does not clarify various aspects of the condensation mechanism and makes the identification of the soft modes...
