FIG. 1.

(Color online) (a) Hamiltonian breathers for E c  = 40 kV/cm, , , , E = 0. (b) Hamiltonian breathers for E c  = 85 kV/cm, , , , E = 0. The effect of higher coercive field and consequently lower value of the nonlinearity on the breather profile is clearly seen.

FIG. 2.

(Color online) (a) Dissipative breathers for E c  = 40 kV/cm, , , , E = 0.1. (b) Dissipative breathers for E c  = 40 kV/cm, , , , E = 0.1. The effect of an increase in damping is noted. (c) Single dissipative breathers for E c  = 40 kV/cm, , , , E = 0.1. The effect of further increase in damping is clearly noticeable as the breathers quickly dissipate. (d) Dissipative bi-breathers for E c  = 40 kV/cm, , , , E = 0.1. The effect of an increase in the interaction term is noted. (e) Dissipative tri-breathers for E c  = 40 kV/cm, , , , E = 0.1. The effect of further increase in the interaction term in creating tri-breathers is also observed.
