Description

We examine the thermodynamic and thermoelectric properties in the stripe phase of high-Tc cuprates, by using the finite-temperature Lanczos technique for the t-J model with a potential that stabilizes vertical charge stripes. When the stripe potential is turned on, the entropy is suppressed as a consequence of the formation of one-dimensional charge stripes accompanied by an enhancement of antiferromagnetic spin correlation in the spin domains. The stripe formation leads also to weak temperature dependence of the chemical potential, leading to the suppression of the thermoelectric power. The suppression of the entropy and thermoelectric power is consistent with experimental data in the stripe phase of La_{1.6-x}Nd_{0.4}Sr_xCuO_4.
