How Much Does Money Matter in a Direct Democracy?
The fine-structure splitting of quantum confined InxGa1-x Nexcitons is investigated using polarization-sensitive photoluminescence spectroscopy. The majority of the studied emission lines exhibits mutually orthogonal fine-structure components split by 100-340 mu eV, as measured from the cleaved edge of the sample. The exciton and the biexciton reveal identical magnitudes but reversed sign of the energy splitting.Original Publication:Supaluck Amloy, Y T Chen, K F Karlsson, K H Chen, H C Hsu, C L Hsiao, L C Chen and Per-Olof Holtz, Polarization-resolved fine-structure splitting of zero-dimensional InxGa1-xN excitons, 2011, PHYSICAL REVIEW B, (83), 20, 201307.http://dx.doi.org/10.1103/PhysRevB.83.201307Copyright: American Physical Societyhttp://www.aps.org
Duality Theorems for Crossed Products over Rings
In this note we extend duality theorems for crossed products obtained by M.
Koppinen and C. Chen from the case of a base field or a Dedekind domain to the
case of an arbitrary noetherian commutative ground ring under fairly weak
conditions. In particular we extend an improved version of the celebrated
Blattner-Montgomery duality theorem to the case of arbitrary noetherian ground
rings.Comment: 24 page

Comment on "On the Crooks fluctuation theorem and the Jarzynski equality" [J. Chem. Phys. 129, 091101 (2008)]
It has recently been argued that a self-consistency condition involving the
Jarzynski equality (JE) and the Crooks fluctuation theorem (CFT) is violated
for a simple Brownian process [L. Y. Chen, J. Chem. Phys. 129, 091101 (2008)].
This note adopts the definitions in the original formulation of the JE and CFT
and demonstrates the contrary.Comment: 2 page
