Effect of biharmonic coupling in frequency-weighted Kuramoto oscillators
R. Senthamizhan, R. Gopal, V. K. Chandrasekar
We investigate the collective dynamics of globally coupled phase oscillators with frequency-weighted biharmonic coupling. Although frequency-weighted and biharmonic extensions of t…
Self-oscillations induced by self-induced torque in magnetic double tunnel junction
R. Arun, R. Gopal, V. K. Chandrasekar +1
Self-oscillations of the magnetization due to self-induced torque (SIT) in a magnetic double tunnel junction that consists of perpendicularly polarized, pinned and free layers is i…
Swarmalators with frequency-weighted interactions
R. Senthamizhan, R. Gopal, V. K. Chandrasekar
We investigate the role of frequency-weighted interactions in a solvable model of one-dimensional (1D) swarmalators confined to a ring, where both spatial and phase couplings are s…
Frustration Induced Chimeras and Motion in Two Dimensional Swarmalators
R. Senthamizhan, R. Gopal, V. K. Chandrasekar
Swarmalators are phase oscillators capable of simultaneous swarming and synchronization, making them potential candidates for replicating complex dynamical states. In this work, we…
Exploration of field-like torque and field-angle tunability in coupled spin-torque nano oscillators for synchronization
R. Arun, R. Gopal, V. K. Chandrasekar +1
We investigate the influence of field-like torque and the direction of the external magnetic field on a one-dimensional array of serially connected spin-torque nano oscillators, ha…
High frequency oscillations in spin-torque nano oscillator due to bilinear coupling
R. Arun, R. Gopal, V. K. Chandrasekar +1
Exchange coupling in an interfacial context is crucial for spin-torque nano oscillator (STNO) that consists of a non-magnetic spacer which is alloyed with a ferromagnetic material.…
