Effects of transcranial alternating current stimulation over right-DLPFC on vigilance tasks depend on the arousal level

Scientific Reports, 2022
Current theoretical accounts on the oscillatory nature of sustained attention predict that entrainment via transcranial alternating current stimulation (tACS) at alpha and theta frequencies on specific areas of the prefrontal cortex could prevent the ...

Synchronized and desynchronized phases of coupled non-equilibrium exciton-polariton condensates

, 2008
We theoretically analyze the synchronized and desynchronized phases of coupled non-equilibrium polariton condensates within mean field theory. An analytical condition for the existence of a synchronized phase is derived for two coupled wells. The case of

Shunt-capacitor-assisted synchronization of oscillations in intrinsic Josephson junctions stack

, 2010
We show that shunt capacitor stabilizes synchronized oscillations in intrinsic Josephson junction stacks biased by DC current. This synchronization mechanism has an effect similar to the previously discussed radiative coupling between junctions, however,

Enhanced synchronization in an array of spin torque nano oscillators in the presence of oscillating external magnetic field

, 2014
We demonstrate that the synchronization of an array of electrically coupled spin torque nano-oscillators (STNO) modelled by Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation can be enhanced appreciably in the presence of a common external microwave ...
