Rigidity of crystalline color superconducting quark matter
Rigidity of crystalline color superconducting quark matter
We calculate the shear modulus of crystalline color superconducting quark matter, showing that this phase of dense, but not asymptotically dense, three-flavor quark matter responds to shear stress like a very rigid solid. To evaluate the shear modulus, we derive the low-energy effective Lagrangian that describes the phonons that originate …
