Quantum Anisotropic Sigma and Lambda Models as Spin Chains
Calan Appadu, Timothy J. Hollowood, Dafydd Price +1
We consider lambda and anisotropic deformations of the SU(2) principal chiral model and show how they can be quantized in the Hamiltonian formalism on a lattice as a suitable spin…
Yang Baxter and Anisotropic Sigma and Lambda Models, Cyclic RG and Exact S-Matrices
Calan Appadu, Timothy J. Hollowood, Dafydd Price +1
Integrable deformation of SU(2) sigma and lambda models are considered at the classical and quantum levels. These are the Yang-Baxter and XXZ-type anisotropic deformations. The XXZ…
Giant Magnons of String Theory in the Lambda Background
Calan Appadu, Timothy J. Hollowood, J. Luis Miramontes +2
The analogues of giant magnon configurations are studied on the string world sheet in the lambda background. This is a discrete deformation of the AdS(5)xS(5) background that prese…
Quantum Inverse Scattering and the Lambda Deformed Principal Chiral Model
Calan Appadu, Timothy J. Hollowood, Dafydd Price
The lambda model is a one parameter deformation of the principal chiral model that arises when regularizing the non-compactness of a non-abelian T dual in string theory. It is a cu…
Beta Function of k Deformed AdS_5 x S^5 String Theory
Calan Appadu, Timothy J. Hollowood
We calculate the one loop beta function for the would-be marginal coupling on the world sheet of the k deformed sigma models associated to a quantum group with q=exp(i pi/k). This…
