Optical evidence for the existence of a stripe structure in the normal and superconducting phases of YbA2Cu3O6+x

We study optical interband absorption spectra of insulator and metallic YBa2Cu3O6+ x films in a wide temperature region which includes the pseudogap and superconducting states. We show that in the pseudogap state a stripe structure appears with polaron-like charge carriers having an antiferromagneti...

Description
Summary:We study optical interband absorption spectra of insulator and metallic YBa2Cu3O6+ x films in a wide temperature region which includes the pseudogap and superconducting states. We show that in the pseudogap state a stripe structure appears with polaron-like charge carriers having an antiferromagnetic core.
