Percolative nature of the dc paraconductivity in the cuprate superconductors

Petar Popčević, Damjan Pelc, Yang Tang +7

We present an investigation of the planar direct-current (dc) paraconductivity of the model cuprate material HgBa${}_2$CuO${}_{4+\delta }$ in the underdoped part of the phase diagram. The si…
