      abstract     = {We present detailed analytic calculations of finite-volume
                      energy spectra, mean field theory, as well as a systematic
                      low-energy effective field theory for the square lattice
                      quantum dimer model. The analytic considerations explain why
                      a string connecting two external static charges in the
                      confining columnar phase fractionalizes into eight distinct
                      strands with electric flux $\frac{1}{4}$. An emergent
                      approximate spontaneously broken $SO(2)$ symmetry gives rise
                      to a pseudo-Goldstone boson. Remarkably, this soft
                      phonon-like excitation, which is massless at the
                      Rokhsar-Kivelson (RK) point, exists far beyond this point.
                      The Goldstone physics is captured by a systematic low-energy
                      effective field theory. We determine its low-energy
                      parameters by matching the analytic effective field theory
                      with exact diagonalization results and Monte Carlo data.
                      This confirms that the model exists in the columnar (and not
                      in a plaquette or mixed) phase all the way to the RK point.},
