We investigate the propagation properties of quadrupole breather in nonlinear media with a nonlocal exponential-decay response by using the variational method and the equivalent particle method. The analytical solution of the quadrupole breather is obtained. The breather beamwidth, the wavefront curvature, the intensity pattern, and the comparisons between the analytical quadrupole breather solution and the numerical simulations of the nonlocal nonlinear Schrödinger equation in the case of highly nonlocal nonlinearity are analyzed. The results...
