Breathers in Hamiltonian PT -Symmetric Chains of Coupled Pendula under a Resonant Periodic Force
We derive a Hamiltonian version of the PT-symmetric discrete nonlinear Schrödinger equation that describes synchronized dynamics of coupled pendula driven by a periodic movement of their common strings. In the limit of weak coupling between the pendula, we classify the existence and spectral stability of breathers (time-periodic solutions localized in the lattice) supported near one pair of cou...
متن کاملImperfect chimera states for coupled pendula
The phenomenon of chimera states in the systems of coupled, identical oscillators has attracted a great deal of recent theoretical and experimental interest. In such a state, different groups of oscillators can exhibit coexisting synchronous and incoherent behaviors despite homogeneous coupling. Here, considering the coupled pendula, we find another pattern, the so-called imperfect chimera stat...
متن کاملThe smallest chimera state for coupled pendula
Chimera states in the systems of coupled identical oscillators are spatiotemporal patterns in which different groups of oscillators can exhibit coexisting synchronous and incoherent behaviors despite homogeneous coupling. Although these states are typically observed in large ensembles of oscillators, recently it has been suggested that chimera states may occur in the systems with small numbers ...
متن کاملThe Dynamics of SQUIDs and Coupled Pendula
Josephson [8] predicted in 1962 that a DC tunnel current would flow between two superconductors connected by a thin insulating layer of thickness less than about 20 Å in the absence of a voltage difference, an effect now called the DC Josephson effect. The quantum-mechanical current, called the superconducting current, arises from the tunneling of Cooper pairs of electrons of opposite spin and ...
متن کاملIntermittent Synchronization in a Pair of Coupled Chaotic Pendula
Numerical simulations have been carried out for a pair of unidirectionally coupled identical pendula under the action of a common external ac torque. Both the master pendulum and the slave pendulum were in chaotic states. The only form of persistent locking appeared to be a computational artifact; otherwise the synchronization of slave to master was found to be intermittent. [S0031-9007(98)0663...
