condensed matter - Low dim physics: Examples of confinement-deconfinement phases of U(1) gauge theory in 2 dimensions


Please provide some examples of confinement-deconfinement phases of U(1) gauge theory in 2 spacetime dimensions (Low dimwnsional physics).


U(1) gauge theory can be:


pure U(1) gauge theory, or


U(1) gauge theory with matter fields (bosonic/fermionic).


It is the best to provide examples for both cases.

Understanding Stagnation point in pitot fluid

What is stagnation point in fluid mechanics. At the open end of the pitot tube the velocity of the fluid becomes zero.But that should result...
