1265. Investigations of the Intermolecular Interactions between Organic Conjugated Monomers, and Conjugated Oligomers and Nanotubes Using Dispersion-Corrected DFT

Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)

Invited Speaker / Conférencier invité

This talk will focus on discussing and analyzing intermolecular interactions between organic conjugated polymers used in organic light-emitting diodes (OLEDs) and between conjugated oligomers and carbon nanotubes (CNTs) in CNT-oligomer composites. Dispersion-corrected density functional theory will be employed to study these systems. The construction of multilayered OLEDs typically involves...

We consider the one-dimensional spin chain for arbitrary spin s on a periodic chain with N sites, H = \sum_i^N ( a (S_i^z)^2 + b S_i^z S_{i+1}^z ), the generalization of the chain that was studied by Blume and Capel. The Hamiltonian only involves the z component of the spin thus it is essentially an Ising model. The Hamiltonian also figures exactly as the anisotropic term in the famous...

1165. The motion of spherical particles in a simple ratcheting system with AC Fields

Hanyang Wang, Gary W. Slater University of Ottawa Ratcheting systems make it possible to control the motion of particles in such a way that it becomes possible to separate mixtures of particles on the basis of various physical properties (such as charge, size, shape, etc.). The ratcheting system that we study is a standard microfluidic channel with symmetry breaking obstacles placed...

1176. Long-term behaviour of granular chains held between walls is really equilibrium.

Granular chains have been the focus of a number of studies, in part due to their numerous applications, ranging from shock absorption and vibration reduction to energy localization. Force impulses to an unloaded granular chain result in a propagating solitary wave (SW), analogous to a soliton of the Korteweg-de Vries equation. When SWs collide with a boundary or another SW, secondary solitary...

1264. Critical noise parameters for fault tolerant quantum computation

Noise is imminent to a quantum computing process. With the help of quantum error correcting codes, the logical information in a qubit can be preserved by encoding it in a system of several physical qubits and by performing gates in a fault tolerant manner. However, it is crucial to know the noise model affecting the physical qubits, in order to estimate the error on the logical qubit and...
