We investigate the time-dependent R\'{e}nyi entanglement entropy after a quantum quench starting from Mott-insulating and charge-density-wave states in one-dimensional free boson system. The second is found to be negative of logarithm permanent matrix consisting single-particle correlation functions. From this relation inequality, we obtain rigorous conditions for satisfying volume-law growth. ...
The rare earth nickelates RNiO3 are metallic at high temperatures and insulating magnetically ordered low temperatures. temperature phase has been predicted to be type II multiferroic, i.e. ferroelectric magnetic order coupled occur simultaneously. Confirmation of those ideas inhibited by the absence experimental data on single crystals. Here we report Raman spectroscopic crystals (R = Y, Er, H...
Magnetization, resistivity, thermal expansion, thermopower, and neutron powder diffraction data are presented for the perovskite manganite Pr0.7Ba0.3MnO3. A distinct ferromagnetic insulating state, similar to that observed in the La0.88Sr0.12MnO3 system, is observed in the temperature range between the paramagneticferromagnetic transition at TFM'180 K and the broad metal-insulator transition ne...
Conductivity and field effect measurements in thin insulating Al granular films are reported. The occurrence of a symmetrical field effect and of very slow conductance relaxations is demonstrated. They are identical to the electron glassy behaviours already reported in insulating indium oxide thin films. The results suggest that the phenomena are quite general. The study of structurally discont...
