Metal-Insulator transitions in the periodic Anderson model
G. Sordi, A. Amaricci, M. J. Rozenberg
We solve the Periodic Anderson model in the Mott-Hubbard regime, using Dynamical Mean Field Theory. Upon electron doping of the Mott insulator, a metal-insulator transition occurs…
Bulk-like d band of SrVO3 under a self-protective cap layer
M. Takizawa, M. Minohara, H. Kumigashira +10
We have performed a detailed angel-resolved photoemission spectroscopy study of in-situ prepared SrVO3 thin films. Naturally capped by a ``transparent'' protective layer, contribut…
Impurity effects in the quantum kagome system ZnCu3(OH)6Cl2
R. Chitra, M. J. Rozenberg
Motivated by the recent experiments on the new spin half Kagome compound ZnCu3(OH)6Cl2, we study a phenomenological model of a frustrated quantum magnet. The model has a spin liqui…
Disorder effects in the quantum kagome antiferromagnet ZnCu3(OH)6Cl2
M. J. Rozenberg, R. Chitra
The recent NMR experiments on ZnCu3(OH)6Cl2 motivate our study of the effect of non- magnetic defects on the antiferromagnetic spin-1/2 kagome lattice. We use exact diagonalization…
Non-volatile resistive switching in dielectric superconductor YBCO
C. Acha, M. J. Rozenberg
We report on the reversible, nonvolatile and polarity dependent resistive switching between superconductor and insulator states at the interfaces of a Au/YBaCuO (YB…
