Antiferromagnetic Ordering on CoO(001) Studied by Metastable Helium Beam Diffraction
P. Banerjee, X. Liu, M. Farzaneh +4
Magnetic diffractive scattering of coherent metastable helium atomic beams from CoO(001) surfaces reveal the presence of an anomalous enhancement in the intensity of the half-order…
Soliton Ratchets Induced by Excitation of Internal Modes
C. R. Willis, M. Farzaneh
Recently Flach et.al. used a symmetry analysis to predict the appearance of directed energy current in homogeneously spatially extended systems coupled to a heat bath in the presen…
Kink Radiation on Small Discrete Periodic Damped Driven Nonlinear sine-Gordon Arrays
C. R. Willis
In this paper, we explain the fundamental properties of the radiation processess of untrapped kinks moving on discrete lattices or any spatially periodic potential. In particular w…
Discrete Breathers
S. Flach, C. R. Willis
Nonlinear classical Hamiltonian lattices exhibit generic solutions in the form of discrete breathers. These solutions are time-periodic and (typically exponentially) localized in s…
Localized Excitations in two-dimensional Hamiltonian Lattices
S. Flach, K. Kladko, C. R. Willis
We analyze the origin and features of localized excitations in a discrete two-dimensional Hamiltonian lattice. The lattice obeys discrete translational symmetry, and the localized…
Nonlinear Localized Excitations and the Dynamics of H-Bonds in DNA
S. Flach, C. R. Willis
We analyze typical models which intend to describe (parts of) the dynamics of H-Bonds in DNA. We show that these models generically allow for nonlinear localized excitatons (NLEs)…
