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…
A Quantum Approach to the Continuum Heisenberg Spin-Chain Model: Position-Dependent Mass Formalism and Pre-canonical Quantization
V. Chithiika Ruby, M. Lakshmanan
Painlevé's singularity structure analysis, combined with stereographic mapping, has previously been applied to a one-dimensional Heisenberg spin-chain continuum model which identif…
Unique multistable states in periodic structures with saturable nonlinearity
S. Vignesh Raja, A. Govindarajan, M. Lakshmanan
We report that conventional saturable periodic structures, in sharp contrast to the conventional systems with different nonlinearities which exhibit the typical S- shaped optical b…
Electromagnetic breathing dromion-like structures in an anisotropic ferromagnetic medium
Sathishkumar Perumal, J. Sivapragasam, M. Lakshmanan
The influence of Gilbert damping on the propagation of electromagnetic waves (EMWs) in an anisotropic ferromagnetic medium is investigated theoretically. The interaction of the mag…
Nonlinear two-component system of time-fractional PDEs in (2+1)-dimensions: Invariant subspace method combined with variable transformation
P. Prakash, K. S. Priyendhu, M. Lakshmanan
In this article, we develop a systematic approach of the invariant subspace method combined with variable transformation to find the generalized separable exact solutions of the no…
Painlevé Analysis, Prelle-Singer Approach, Symmetries and Integrability of Damped Hénon-Heiles System
C. Uma Maheswari, N. Muthuchamy, V. K. Chandrasekar +2
We consider a modified damped version of Hénon-Heiles system and investigate its integrability. By extending the Painlevé analysis of ordinary differential equations we find that t…
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…
Simulation of universal optical logic gates under energy sharing collisions of Manakov solitons and fulfillment of practical optical logic criteria
M. Vijayajayanthi, T. Kanna, M. Lakshmanan
The universal optical logic gates, namely NAND and NOR gates, have been theoretically simulated by employing the energy sharing collision of bright optical solitons in the Manakov…
