Abstract: Abstract Magnetic properties of polycrystalline La1-xCaxMn0.9Cu0.1O3 (0.02 ≤ x ≤ 0.4) have been investigated in detail. All samples show a clear ferromagnetic-paramagnetic transition. The Curie temperature TC decreases with increasing Ca-dopant. Inverse susceptibility of all the samples deviates from… read more here.

Abstract: A quantum two-level system immersed in a sub-Ohmic bath experiences enhanced low-frequency quantum statistical fluctuations which render the nonequilibrium quantum dynamics highly non-Markovian. Upon using the numerically exact time-evolving matrix product operator approach, we investigate… read more here.
