Statistical mechanics of general discrete nonlinear Schr{ö}dinger models: Localization transition and its relevance for Klein-Gordon lattices
Magnus Johansson, Kim O. Rasmussen
We extend earlier work [Phys.Rev.Lett. 84, 3740 (2000)] on the statistical mechanics of the cubic one-dimensional discrete nonlinear Schrodinger (DNLS) equation to a more general c…
Exact Solutions of the Saturable Discrete Nonlinear Schrodinger Equation
Avinash Khare, K. O. Rasmussen, M. R. Samuelsen +1
Exact solutions to a nonlinear Schr{ö}dinger lattice with a saturable nonlinearity are reported. For finite lattices we find two different standing-wave-like solutions, and for an…
Detecting Breather Excitations with Inelastic Tunneling Spectroscopy
Jian-Xin Zhu, K. O. Rasmussen, A. R. Bishop +1
We propose inelastic electron tunneling spectroscopy scanning tunneling microscopy (IETS-STM) as a means of exciting and observing intrinsic localized modes (breathers) in a macrom…
Origins of elastic properties in ordered nanocomposites
R. B. Thompson, K. O. Rasmussen, T. Lookman
We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock…
Parametric Quantum Resonances for Bose-Einstein Condensates
P. G. Kevrekidis, A. R. Bishop, K. Ø. Rasmussen
We generalize recent work on parametric resonances for nonlinear Schr{ö}dinger (NLS) type equations to the case of three dimensional Bose-Einstein condensates at zero temperatures.…
Models for energy and charge transport and storage in biomolecules
Serge F. Mingaleev, Peter L. Christiansen, Yuri B. Gaididei +2
Two models for energy and charge transport and storage in biomolecules are considered. A model based on the discrete nonlinear Schrodinger equation with long-range dispersive inter…
