Ambient-pressure bulk superconductivity deep in the magnetic state of CeRhIn5
Johnpierre Paglione, P. -C. Ho, M. B. Maple +4
Specific heat, magnetic susceptibility and electrical transport measurements were performed at ambient pressure on high-quality single crystal specimens of CeRhIn5 down to ultra-lo…
Reply to comment by Y. Ando on "Onset of Boson Mode at the Superconducting Critical Point of Underdoped YBaCuO" by N. Doiron-Leyraud et al
Nicolas Doiron-Leyraud, Louis Taillefer
In a recent Comment [arXiv:0711.4654], Y. Ando raises two valid issues in relation to our low-temperature heat transport study of YBaCuO across the insulator-to-superco…
The Hubbard model on the triangular lattice: Spiral order and spin liquid
Peyman Sahebsara, David Sénéchal
We investigate the half-filled Hubbard model on an isotropic triangular lattice with the variational cluster approximation. By decreasing the on-site repulsion (or equivalently…
Observation of Berry's Phase in a Solid State Qubit
P. J. Leek, J. M. Fink, A. Blais +7
In quantum information science, the phase of a wavefunction plays an important role in encoding information. While most experiments in this field rely on dynamic effects to manipul…
Magnetism and d-wave superconductivity on the half-filled square lattice with frustration
Andriy H. Nevidomskyy, Christian Scheiber, David Senechal +1
The role of frustration and interaction strength on the half-filled Hubbard model is studied on the square lattice with nearest and next-nearest neighbour hoppings t and t' using t…
The quantum vs classical aspects of one dimensional electron-phonon systems revisited by the renormalization group method
H. Bakrim, C. Bourbonnais
An extension of the renormalization group method that includes the effect of retardation for the interactions of a fermion gas is used to re-examine the quantum and classical prope…
