摘要：
A closed form, explicit expression for a chiral interaction potential between two rigid helices at arbitrary, fixed mutual orientations was derived. This bare, 'ground state' pair potential has a complex landscape and a number of nontrivial features. As an illustration of possible manifestations of pair potential features in real phenomena, an attempt was made to qualitatively rationalize some of the observed properties of cholesteric aggregates of DNA.
