No spin-localization phase transition in the spin-boson model without local field
Tao Liu, Mang Feng, Lei Li +2
We explore the spin-boson model in a special case, i.e., with zero local field. In contrast to previous studies, we find no possibility for quantum phase transition (QPT) happening…

The same superconducting criticality for underdoped and overdoped La_{2-x}Sr_xCuO_4 single crystals
H. H. Wen, X. H. Chen, W. L. Yang +1
By measuring the superconducting diamagnetic moments for an underdoped and an overdoped La_{2-x}Sr_xCuO_4 single crystal with equal qualities and roughly equal transition temperatu…
