abstract = {Recently, the collective phase behaviors of charged
DNA-viruses (rods) are explored in various low ionic
strengths, where much slowing down relaxations are observed
in equilibrium. These phases are distinguished by crossing
the critical ionic strength, where the salt-dependent
effective microscopic dynamics are important with
non-monotonic multi-phase boundaries. This is also
interested in terms of phase transition and replica symmetry
breaking (RSB), realized by the divergence of relaxation
time and the exponent power of correlation lengths in
dynamic disorderorder transitions. RSB occurs as the result
of many-body interactions of randomized orientations. Here,
in this paper, one of the chiral mesophases, the X-pattern
is highlighted for its long-time metastable state consisting
of cavity loops bounded within the planar nematic, as a new
type of a glass, noted as a chiral glass. The chiral glass
is discussed in terms of the divergences for relaxations in
the characteristic time as well the inverse of an optical
pitch length, which are analyzed in the long-time-lapsed
orientation textures via image-time correlations. The
outcome highlights interesting aspects of charge effect in
the 'twist' elasticity energy for optimizing the long-ranged
repulsive electrostatic interactions among charged DNA
rods.},
