Question about Monopole Operator
I've been studying IR-dualities in 2+1 dimensions. I encountered monopole operators in the following paper:
Time-Reversal Symmetry, Anomalies, and Dualities in (2+1)d
On page 10, starting from $QED …

Question about Charge and Gauge Transformation
Does gauge invariance imply charge neutrality? I understand that all physical observables must be gauge invariant. Does this mean that physical observables must be neutral?
If a quark is in red, a g …

Why did David Tong say that the global topological $U(1)$ symmetry is unbroken in Higgs phase?
In the paper A Duality Web in 2+1 Dimensions and Condensed Matter Physics by Seiberg, Senthil, Wang, and Witten, they studied the particle-vortex dualities in $2+1$ dimensions.
On page 20, section 3. …
