Effects of molecular dipole orientation on the exciton binding energy of CH3NH3PbI3
(2016)
We present a simple interacting tight-binding model for excitons, which is used to investigate the dependence
of the exciton binding energy of CH

Tunable and long-range energy transfer efficiency through a graphene nanodisk
(2016)
In this paper, we present a theoretical investigation of the energy transfer efficiency between a pair of quantum emitters placed in proximity to a conducting graphene nanodisk. The energy transfer efficiency quantifies ...
Statistical studies of on-line complex systems : a social network and a betting exchange
(Trinity College (Dublin, Ireland). School of Physics, 2011)
In recent years, the complexity that arises out of collective social and economic
behaviour has become a popular research subject for physicists. In particular, the
fields of complex network science and econophysics have ...
Dynamic behavior of a piezowalker, inertial and frictional configurations
(American Institute of Physics, 1999)
We have examined two configurations of a piezowalker, the inertial and the frictional one, both of which are capable of moving samples with submicrometer steps over a distance of some millimeters. We demonstrated that, ...
The Crystal Structure of Bubbles in the Wet Foam Limit (Amendment)
(Royal Society of Chemistry, 2006)
We have observed a rich variety of three-dimensional crystal
and defect structures spontaneously formed by small (diameter
200 mm) bubbles in a wet foam. The observations confirm and
extend those made by Bragg and Nye ...
Atomic scale spin-dependent STM on magnetite using antiferromagnetic STM tips
(2005)
STM tips made from antiferromagnetic MnNi have been used to investigate the atomic structure of the (001) and (111) surfaces of Fe3O4. The clean (001) surface displays a (root 2 x root 2)R45 degrees superlattice, which is ...
Optimising Transport in a Homogeneous Network
(American Physical Society, 2004)
Many situations in physics, biology, and engineering consist of the transport of some physical quantity
through a network of narrow channels. The ability of a network to transport such a quantity in every direction
can ...
Torque in nested Halbach cylinders

Anomalous magnetization reversal due to proximity effect of antiphase boundaries
(2011)
Here we report anomalous double switching hysteresis loop and high coercivity (~0.1 T) in Fe3O4(110) thin films. Our analytical model based on spin chains confined within small antiphase boundary domains (APBDs) suggests ...
Magnetic structuring of linear copper electrodeposits
(2012)
Electrodeposition of copper is investigated in localized magnetic fields produced by linear arrays
of permanent magnets. The thickness and texture of the deposits depend on the magnitude and
direction of the field. The ...
