Physicists developed simplified formulas to quantify quantum entanglement in strongly correlated electron systems. Their approach was applied to nanoscale materials, revealing unexpected quantum ...

Scientists from Tomsk Polytechnic University have presented a new approach to the asymptotic description of open nonlinear quantum systems. It is based on the quasi–classical approximation, a kind of ...

Students often struggle with temperature conversions in science courses due to time constraints. A simplified approximation method offers a solution by using basic arithmetic: double Celsius and add ...

Standard life contingency formulas are shown to have matrix analogues. The derivation of these multidimensional forms permits simple solutions to multiple contingency problems, including moves in and ...
