Navigating the gAI Landscape: Insights from a Physics Education Survey (2024)
Journal Article
Zambon, C., Mizouri, A., & Stevenson, C. (2024). Navigating the gAI Landscape: Insights from a Physics Education Survey. Enhancing Teaching and Learning in Higher Education, 2, 16-38. https://doi.org/10.62512/etlhe.15

A survey of physics students at Durham University sheds some light on the students' current use and understanding of gAI and their concerns for the future and the education sector. Physics students highlight that the main use of gAI is for computatio... Read More about Navigating the gAI Landscape: Insights from a Physics Education Survey.

Integrable defects at junctions within a network (2020)
Journal Article
Corrigan, E., & Zambon, C. (2020). Integrable defects at junctions within a network. Journal of Physics A: Mathematical and Theoretical, 53(48), Article 484001. https://doi.org/10.1088/1751-8121/abbec3

The purpose of this article is to explore the properties of integrable, purely transmitting, defects placed at the junctions of several one-dimensional domains within a network. The defect sewing conditions turn out to be quite restrictive—for exampl... Read More about Integrable defects at junctions within a network.

Type II defects revisited (2018)
Journal Article
Corrigan, E., & Zambon, C. (2018). Type II defects revisited. Journal of High Energy Physics, 2018(09), Article 019. https://doi.org/10.1007/jhep09%282018%29019

Energy and momentum conservation in the context of a type II, purely transmitting, defect, within a single scalar relativistic two-dimensional field theory, places a severe constraint not only on the nature of the defect but also on the potentials fo... Read More about Type II defects revisited.

The classical nonlinear Schrödinger model with a new integrable boundary (2014)
Journal Article
Zambon, C. (2014). The classical nonlinear Schrödinger model with a new integrable boundary. Journal of High Energy Physics, 2014(08), Article 036. https://doi.org/10.1007/jhep08%282014%29036

A new integrable boundary for the classical nonlinear Schrödinger model is derived by dressing a boundary with a defect. A complete investigation of the integrability of the new boundary is carried out in the sense that the boundary K matrix is deriv...

Integrable defects in affine Toda field theory and infinite-dimensional representations of quantum groups (2010)
Journal Article
Corrigan, E., & Zambon, C. (2010). Integrable defects in affine Toda field theory and infinite-dimensional representations of quantum groups. Nuclear Physics B, 848(3), 545-577. https://doi.org/10.1016/j.nuclphysb.2011.03.007

Transmission matrices for two types of integrable defect are calculated explicitly, first by solving directly the nonlinear transmission Yang–Baxter equations, and second by solving a linear intertwining relation between a finite-dimensional represen...

A transmission matrix for a fused pair of integrable defects in the sine-Gordon model. (2010)
Journal Article
Corrigan, E., & Zambon, C. (2010). A transmission matrix for a fused pair of integrable defects in the sine-Gordon model. Journal of Physics A: Mathematical and Theoretical, 43, Article 345201. https://doi.org/10.1088/1751-8113/43/34/345201

Within the quantum sine-Gordon model a transmission matrix describing the scattering of a soliton with a fused pair of integrable defects is proposed. The result is consistent with the classical picture of scattering and highlights the differences be...

Jump-defects in the nonlinear Schrodinger model and other non-relativistic field theories. (2005)
Journal Article

Recent work on purely transmitting 'jump-defects' in the sine-Gordon model and other relativistic field theories is extended to non-relativistic models. In all the cases investigated the defect conditions are provided by 'frozen' Bäcklund transformat...

Some aspects of jump-defects in the quantum sine-Gordon model (2005)
Journal Article
Bowcock, P., Corrigan, E., & Zambon, C. (2005). Some aspects of jump-defects in the quantum sine-Gordon model. Journal of High Energy Physics, 2005(08), Article 023. https://doi.org/10.1088/1126-6708/2005/08/023

The classical sine-Gordon model permits integrable discontinuities, or jump-defects, where the conditions relating the fields on either side of a defect are Bäcklund transformations frozen at the defect location. The purpose of this article is to exp... Read More about Some aspects of jump-defects in the quantum sine-Gordon model.

Classically integrable field theories with defects. (2004)
Journal Article
Bowcock, P., Corrigan, E., & Zambon, C. (2004). Classically integrable field theories with defects. International Journal of Modern Physics A, 19(supp02), 82-91. https://doi.org/10.1142/s0217751x04020324

Some ideas and remarks are presented concerning a possible Lagrangian approach to the study of internal boundary conditions relating integrable fields at the junction of two domains. The main example given in the article concerns single real scalar f... Read More about Classically integrable field theories with defects..

Affine Toda field theories with defects (2004)
Journal Article

A lagrangian approach is proposed and developed to study defects within affine Toda field theories. In particular, a suitable Lax pair is constructed together with examples of conserved charges. It is found that only those models based on ar(1) data... Read More about Affine Toda field theories with defects.
