The U(1)×SU(2) Chern–Simons gauge theory is applied to study the 2D t–J model describing the normal state of underdoped cuprate superconductors. The U(1) field produces a flux phase for holons converting them into Dirac-like fermions, while the SU(2) field, due to the coupling to holons gives rise to a gap for spinons. An effective low-energy action involving holons, spinons and a self-generated U(1) gauge field is derived. The Fermi surface and electron spectral function obtained are consistent with photoemission experiments. The theory predicts a minimal gap proportional to doping concentration. It also explains anomalous transport properties.

Three-state model for quasi-two dimensional Cu-O layer of oxide superconductor is considered. The density of states and transport properties (resistivity and thermo-electric power) in normal state are calculated for resonance and non-resonance condition of Cu d-level and O p-level. Thermoelectric power can be positive or negative depending on carrier concentration, bare charge transfer gap and transfer integral between d–p and p–p states and its sign changes at higher temperature. The thermo-electric power when positive passes through a maximum with increase in temperature. The value at its maximum and its location moves up with decrease in carrier concentration. The thermal variation of resistivity changes from metallic like (linear in -T) to semiconducting-like as carrier concentration reduces by small amount.
