Appearance of photonic minibands in disordered photonic crystals (2003)
Journal Article
Kaliteevski, M., Manzanares Martinez, J., Cassagne, D., Albert, J., Brand, S., & Abram, R. (2003). Appearance of photonic minibands in disordered photonic crystals. Journal of Physics: Condensed Matter, 15(6), 785-790. https://doi.org/10.1088/0953-8984/15/6/305

We have demonstrated the appearance of photonic minibands within the photonic bandgaps of a disordered system represented by randomly distributed 'vacancies' of air cylinders. The positions of the photonic minibands are defined by the energies of the... Read More about Appearance of photonic minibands in disordered photonic crystals.

Increasing the efficiency of erbium-based sources using silicon quantum dots - Discussion (2003)
Journal Article
Abram, R., Kenyon, A., Stoneham, A., & Dobson, P. (2003). Increasing the efficiency of erbium-based sources using silicon quantum dots - Discussion. Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 361(1803), 361-362. https://doi.org/10.1098/rsta.2002.1132

Silicon nanoclusters exhibit novel and interesting optical and electrical properties that are not observed in bulk silicon. Moreover, it has been discovered that there exists a strong coupling between nanoclusters and rare–earth ions that results in...

A comparison of gas dynamics in smooth particle hydrodynamics and semi-analytic models of galaxy formation (2003)
Journal Article
Helly, J., Cole, S., Frenk, C., Baugh, C., Benson, A., Lacey, C., & Pearce, F. (2003). A comparison of gas dynamics in smooth particle hydrodynamics and semi-analytic models of galaxy formation. Monthly Notices of the Royal Astronomical Society, 338(4), 913-925. https://doi.org/10.1046/j.1365-8711.2003.06152.x

We compare the results of two techniques used to calculate the evolution of cooling gas during galaxy formation: smooth particle hydrodynamics (SPH) simulations and semi-analytic modelling. We improve upon the earlier statistical comparison of Benson... Read More about A comparison of gas dynamics in smooth particle hydrodynamics and semi-analytic models of galaxy formation.

Galaxy formation using halo merger histories taken from N-body simulations (2003)
Journal Article
Helly, J., Cole, S., Frenk, C., Baugh, C., Benson, A., & Lacey, C. (2003). Galaxy formation using halo merger histories taken from N-body simulations. Monthly Notices of the Royal Astronomical Society, 338(4), 903-912. https://doi.org/10.1046/j.1365-8711.2003.06151.x

We develop a hybrid galaxy formation model that uses outputs from an N-body simulation to follow the merger histories (or ‘merger trees’) of dark matter haloes and treats baryonic processes, such as the cooling of gas within haloes and subsequent sta...

The inner structure of ΛCDM haloes - I. A numerical convergence study (2003)
Journal Article
Power, C., Navarro, J., Jenkins, A., Frenk, C., White, S., Springel, V., …Quinn, T. (2003). The inner structure of ΛCDM haloes - I. A numerical convergence study. Monthly Notices of the Royal Astronomical Society, 338(1), 14-34. https://doi.org/10.1046/j.1365-8711.2003.05925.x

We present a comprehensive set of convergence tests which explore the role of various numerical parameters on the equilibrium structure of a simulated dark matter halo. We report on results obtained with two independent, state-of-the-art, multi-stepp... Read More about The inner structure of ΛCDM haloes - I. A numerical convergence study.

Local field and aggregation dependence of the micro- and macroscopic optical non-linearity of zwitterionic molecules (2003)
Journal Article
Cross, G., Hackman, N., Thomas, P., Szablewski, M., Pålsson, L., & Bloor, D. (2003). Local field and aggregation dependence of the micro- and macroscopic optical non-linearity of zwitterionic molecules. Optical Materials, 21(1-3), 29-37. https://doi.org/10.1016/s0925-3467%2802%2900108-8

When a dipolar-conjugated molecule can lower its energy through gaining aromaticity, there can be a quite dramatic evolution of its polarisation properties dependent on the local reaction field generated in its environment. We have studied conjugated... Read More about Local field and aggregation dependence of the micro- and macroscopic optical non-linearity of zwitterionic molecules.

Direct measurement of twist mosaic in epitaxial GaN. (2003)
Journal Article
Lafford, T., Ryan, P., Joyce, D., Goorsky, M., & Tanner, B. (2003). Direct measurement of twist mosaic in epitaxial GaN. physica status solidi (a) – applications and materials science, 195(1), 265-270. https://doi.org/10.1002/pssa.200306270

The laboratory application of grazing incidence in-plane X-ray diffraction to the measurement of the in-plane (twist) mosaic of GaN epitaxial layers is demonstrated. Only a single measurement containing no extrapolation uncertainty is required. The r... Read More about Direct measurement of twist mosaic in epitaxial GaN..
