Query: Is there a crystalline state of nuclear matter?   A possibility of the crystalline state of nuclear matter is discussed in a
medium--modified Skyrme model. The interaction energy per nucleon in nuclear
matter is evaluated by taking into account the medium influence on single
nucleon--skyrmion properties and the tensor part of the nucleon--nucleon
potential, and by using a variational method of Hartree--Fock type including
zero--point quantum fluctuations. It is shown that in this approach the ground
state of nuclear matter has no crystalline structure due to quantum
fluctuations as well as medium modifications of hadron properties.
