The author's calculations show that magnetic skyrmions in metallic multilayers such as Co/Pt can be controllably moved on surfaces, simply by using a focused laser beam. Temperature gradients at the spot directly yield skyrmion motion, due to temperature dependence of parameters, but another contribution even more important: Thermoelastic lattice expansion results strain-induced local gradient ...

At present, Boolean algebra based computations by the use of silicon based semiconductor technology are irreversible in nature. This is due to the mismatch of number of inputs and outputs. Reversible logic circuit maps unique input to the output and ensure one to one mapping and basis for emerging applications like low-power design, quantum computation, optical computing, bioinformatics and nan...
