  Empirical evidence in heavy fermion, pnictide, and other systems suggests
that unconventional superconductivity appears associated to some form of
real-space electronic order. For the cuprates, despite several proposals, the
emergence of order in the phase diagram between the commensurate
antiferromagnetic state and the superconducting state is not well understood.
Here we show that in this regime doped holes assemble in "electronic polymers."
Within a Monte Carlo study we find, that in clean systems by lowering the
temperature the polymer melt condenses first in a smectic state and then in a
Wigner crystal both with the addition of inversion symmetry breaking. Disorder
blurs the positional order leaving a robust inversion symmetry breaking and a
nematic order, accompanied by vector chiral spin order and with the persistence
of a thermodynamic transition. Such electronic phases, whose properties are
reminiscent of soft-matter physics, produce charge and spin responses in good
accord with experiments.
