Entanglement and apparent thermality in simulated black holes
Iason A. Sofos, Andrew Hallam, Jiannis K. Pachos
We investigate the apparent thermality of Hawking radiation in the semi-classical limit of quantum black holes using the mean-field limit of a chiral spin-chain simulator, which mo…
AdS/CFT Correspondence with a 3D Black Hole Simulator
Aydin Deger, Matthew D. Horner, Jiannis K. Pachos
One of the key applications of AdS/CFT correspondence is the duality it dictates between the entanglement entropy of Anti-de Sitter (AdS) black holes and lower-dimensional conforma…
Centrifugal deformations of the gravitational kink
Paolo Maraner, Jiannis K. Pachos
The Kaluza-Klein reduction of 4d conformally flat spacetimes is reconsidered. The corresponding 3d equations are shown to be equivalent to 2d gravitational kink equations augmented…
Universal Features of Dimensional Reduction Schemes from General Covariance Breaking
Paolo Maraner, Jiannis K. Pachos
Many features of dimensional reduction schemes are determined by the breaking of higher dimensional general covariance associated with the selection of a particular subset of coord…
Interactions in Abelian and Yang-Mills Theories
Jiannis Pachos
There is a natural way to study the long distance interactions of gauge theories in the electric (momentum) representation. Here, the main ideas are presented for the Abelian and Y…
Fast Lane for Confinement
Jiannis Pachos
Within the Electric Schroedinger Representation of the Yang-Mills theory the Hamiltonian eigenstate and eigenvalue, as well as the Coulomb and confining potentials are presented fo…
Schroedinger Representation of CP(N) Model for Large N
Phillial Oh, Jiannis Pachos
We examine the 1+1 dimensional CP(N) model in the large N limit by using the Schroedinger representation. Starting from the Hamiltonian analysis of the model, we present the variat…
Conformal Symmetry and the Three Point Function for the Gravitational Axial Anomaly
Jiannis Pachos, Ricardo Schiappa
This work presents a first study of a radiative calculation for the gravitational axial anomaly in the massless Abelian Higgs model. The two loop contribution to the anomalous corr…
(1+1)-Dimensional SU(N) Static Sources in E and A Representations
Jiannis Pachos
Here is presented a detailed work on the (1+1) dimensional SU(N) Yang-Mills theory with static sources. By studying the structure of the SU(N) group and of the Gauss' law we constr…
The Coulomb Branch of Yang-Mills Theory from the Schroedinger Representation
Jiannis Pachos
The Coulomb branch of the potential between two static colored sources is calculated for the Yang-Mills theory using the electric Schroedinger representation.
Static Colored SU(2) Sources in (1+1)-Dimensions - An Analytic Solution in the Electric Representation
Jiannis Pachos, Antonios Tsapalis
Within the Schroedinger Electric Representation we analytically calculate the complete wave functional obeying Gauss' law with static SU(2) sources in (1+1)-dimensions. The effecti…
Virasoro Algebra and O(N) Sigma Model
Jiannis Pachos
Within the framework of a local expansion of the logarithm of the O(N) sigma-model vacuum functional, valid for slowly varying fields, the modified Virasoro algebra is studied. The…
Short Distance Properties from Large Distance Behaviour
Paul Mansfield, Marcos Sampaio, Jiannis Pachos
For slowly varying fields the vacuum functional of a quantum field theory may be expanded in terms of local functionals. This expansion satisfies its own form of the Schrödinger eq…
Second Order Calculations of the O(N) sigma-Model Laplacian
Jiannis Pachos
For slowly varying fields on the scale of the lightest mass the logarithm of the vacuum functional of a massive quantum field theory can be expanded in terms of local functionals s…
The O(N) sigma-model Laplacian
Paul Mansfield, Jiannis Pachos
For fields that vary slowly on the scale of the lightest mass the logarithm of the vacuum functional of a massive quantum field theory can be expanded in terms of local functionals…
