+A paradigmatic example where the symmetry of an ordered phase remains unknown is in \urusi.
 \urusi is a heavy fermion superconductor in which superconductivity condenses out of a 
 symmetry broken state referred to as hidden order (HO) [cite pd paper], and at sufficiently
 large [hydrostatic?] pressures, both give way to local moment antiferromagnetism.

 Many [all?] of these theories rely on the formulation of a microscopic model for the

 that studies the HO transition using resonant ultrasound spectroscopy (RUS). 
 RUS is an experimental technique that measures mechanical resonances of a sample. These
 resonances contain information about the full elastic tensor of the material. Moreover, 
 the frequency locations of the resonances are sensitive to symmetry breaking at an electronic

+phase transition due to electron-phonon coupling [cite]. Ref.~\cite{ghosh:apa2019a} uses this information
 to place strict thermodynamic bounds on the symmetry of the HO OP, again, independent of 
 any microscopic model. Motivated by these results, in this paper we consider a mean field theory
 of an OP coupled to strain and the effect that the OP symmetry has on the elastic response
 in different symmetry channels. Our study finds that a single possible OP symmetry
 reproduces the experimental strain susceptibilities, and fits the experimental data well.
 
+We first present a phenomenological Landau-Ginzburg mean field theory of strain coupled to an

+to the experimentally obtained phase diagram of \urusi. 
+Then we compute the elastic response to strain, and examine the response function dependence on
+the symmetry of the OP.
+We proceed to compare the results from mean field theory with data from RUS experiments.
+We further examine the consequences of our theory at non-zero applied pressure in comparison
+with recent x-ray scattering experiments [cite].
+Finally, we discuss our conclusions and future experimental and theoretical work that our results motivate.

 The point group of \urusi is \Dfh, and any coarse-grained theory must locally
 respect this symmetry. We will introduce a phenomenological free energy density
 in three parts: that of the strain, the order parameter, and their interaction.
