We numerically investigate the necessary ingredients for reentrant behavior in the phase diagram of physical systems. Studies on the possibly simplest model that exhibits reentrance, the two-dimensional random-bond Ising model, show that reentrant behavior is generic whenever frustration is present in the model. For both discrete and continuous disorder distributions, the phase diagram in the d...
We report the crystal structure and dielectric properties of a pure H2O@C60 crystal at low temperature. The caged water molecules free from the hydrogen bonds rotate even at 8 K. The antifreeze rotating water molecules respond to an external electric field due to their permanent dipole moment.
night work can have a significant impact on health, well-being, performance and occupational safety of workers. night workers often complain about the sleep disorder characterized by excessive sleepiness. the aim of the study was to determine the level of sleepiness among night workers and investigate its relationship with oral temperature in a hot industry. this cross-sectional study involved...
We report a first-order structurally-driven Mott transition a t T=357 K in single crystal Ca2RuO4, an isomorph to the superconductor Sr2RuO4. A discontinuous jump in electrical resistivity with a concomitant change in magnetic moment is triggered by a pronounced structural transition from a high temperature tetragonal phase to a low temperature orthorhombic phase. We argue that t h e elastic en...
We investigate experimentally the entropy transfer between two distinguishable atomic quantum gases at ultralow temperatures. Exploiting a species-selective trapping potential, we are able to control the entropy of one target gas in presence of a second auxiliary gas. With this method, we drive the target gas into the degenerate regime in conditions of controlled temperature by transferring ent...
