Quantum Phase Transitions in a Cuprate Superconductor Bi_{2}Sr_{2-x}La_{x}CuO_{6+δ}

Yoichi Ando, S. Ono, X. F. Sun +4

To elucidate a quantum phase transition (QPT) in Bi_2Sr_{2-x}La_xCuO_{6+δ}, we measure charge and heat transport properties at very low temperatures and examine the following chara…
