Asymmetric Galilean conformal algebras
Eric Ragoucy, Jorgen Rasmussen, Christopher Raymond
The usual Galilean contraction procedure for generating new conformal symmetry algebras takes as input a number of symmetry algebras which are equivalent up to central charge. We d…
Critical behaviour of loop models on causal triangulations
Bergfinnur Durhuus, Xavier Poncini, Jorgen Rasmussen +1
We introduce a dense and a dilute loop model on causal dynamical triangulations. Both models are characterised by a geometric coupling constant and a loop parameter in such…
Staggered modules of superconformal minimal models
Christopher Raymond, David Ridout, Jorgen Rasmussen
We investigate a class of reducible yet indecomposable modules over the superconformal algebras. These so-called staggered modules exhibit a non-diagonalisable action of the…
Multi-graded Galilean conformal algebras
Eric Ragoucy, Jorgen Rasmussen, Christopher Raymond
Galilean conformal algebras can be constructed by contracting a finite number of conformal algebras, and enjoy truncated -graded structures. Here, we present a generali…
Higher-order Galilean contractions
Jorgen Rasmussen, Christopher Raymond
A Galilean contraction is a way to construct Galilean conformal algebras from a pair of infinite-dimensional conformal algebras, or equivalently, a method for contracting tensor pr…
Galilean contractions of -algebras
Jorgen Rasmussen, Christopher Raymond
Infinite-dimensional Galilean conformal algebras can be constructed by contracting pairs of symmetry algebras in conformal field theory, such as -algebras. Known examples includ…
Integrability and conformal data of the dimer model
Alexi Morin-Duchesne, Jorgen Rasmussen, Philippe Ruelle
The central charge of the dimer model on the square lattice is still being debated in the literature. In this paper, we provide evidence supporting the consistency of a desc…
Fusion rules for the logarithmic superconformal minimal models I: the Neveu-Schwarz sector
Michael Canagasabey, Jorgen Rasmussen, David Ridout
It is now well known that non-local observables in critical statistical lattice models, polymers and percolation for example, may be modelled in the continuum scaling limit by loga…
Boundary algebras and Kac modules for logarithmic minimal models
Alexi Morin-Duchesne, Jorgen Rasmussen, David Ridout
Virasoro Kac modules were initially introduced indirectly as representations whose characters arise in the continuum scaling limits of certain transfer matrices in logarithmic mini…
Critical dense polymers with Robin boundary conditions, half-integer Kac labels and fermions
Paul A. Pearce, Jorgen Rasmussen, Ilya Yu. Tipunin
For general Temperley-Lieb loop models, including the logarithmic minimal models with coprime integers, we construct an infinite family of Robin boundary c…
Logarithmic Superconformal Minimal Models
Paul A. Pearce, Jorgen Rasmussen, Elena Tartaglia
The higher fusion level logarithmic minimal models LM(P,P';n) have recently been constructed as the diagonal GKO cosets (A_1^{(1)})_k oplus (A_1^{(1)})_n / (A_1^{(1)})_{k+n} where…
Coset construction of logarithmic minimal models: branching rules and branching functions
Paul A. Pearce, Jorgen Rasmussen
Working in the Virasoro picture, it is argued that the logarithmic minimal models LM(p,p')=LM(p,p';1) can be extended to an infinite hierarchy of logarithmic conformal field theori…
Modular invariant partition function of critical dense polymers
Alexi Morin-Duchesne, Paul A. Pearce, Jorgen Rasmussen
A lattice model of critical dense polymers is solved exactly for arbitrary system size on the torus. More generally, an infinite family of lattice loop models is studied on the tor…
W-extended Kac representations and integrable boundary conditions in the logarithmic minimal models WLM(1,p)
Jorgen Rasmussen
We construct new Yang-Baxter integrable boundary conditions in the lattice approach to the logarithmic minimal model WLM(1,p) giving rise to reducible yet indecomposable representa…
Classification of Kac representations in the logarithmic minimal models LM(1,p)
Jorgen Rasmussen
For each pair of positive integers r,s, there is a so-called Kac representation (r,s) associated with a Yang-Baxter integrable boundary condition in the lattice approach to the log…
Coset Graphs in Bulk and Boundary Logarithmic Minimal Models
Paul A. Pearce, Jorgen Rasmussen
The logarithmic minimal models are not rational but, in the W-extended picture, they resemble rational conformal field theories. We argue that the W-projective representations are…
On the CFT duals for near-extremal black holes
Jorgen Rasmussen
We consider Kerr-Newman-AdS-dS black holes near extremality and work out the near-horizon geometry of these near-extremal black holes. We identify the exact U(1)_L x U(1)_R isometr…
A near-NHEK/CFT correspondence
Jorgen Rasmussen
We consider excitations around the recently introduced near-NHEK metric describing the near-horizon geometry of the near-extremal four-dimensional Kerr black hole. This geometry ha…
Graph fusion algebras of WLM(p,p')
Jorgen Rasmussen
We consider the W-extended logarithmic minimal model WLM(p,p'). As in the rational minimal models, the so-called fundamental fusion algebra of WLM(p,p') is described by a simple gr…
Solvable Critical Dense Polymers on the Cylinder
Paul A. Pearce, Jorgen Rasmussen, Simon P. Villani
A lattice model of critical dense polymers is solved exactly on a cylinder with finite circumference. The model is the first member LM(1,2) of the Yang-Baxter integrable series of…
A note on Kerr/CFT and free fields
Jorgen Rasmussen
The near-horizon geometry of the extremal four-dimensional Kerr black hole and certain generalizations thereof has an SL(2,R) x U(1) isometry group. Excitations around this geometr…
Isometry-preserving boundary conditions in the Kerr/CFT correspondence
Jorgen Rasmussen
The near-horizon geometries of the extremal Kerr black hole and certain generalizations thereof are considered. Their isometry groups are all given by SL(2,R) x U(1). The usual bou…
Fusion matrices, generalized Verlinde formulas, and partition functions in WLM(1,p)
Jorgen Rasmussen
The infinite series of logarithmic minimal models LM(1,p) is considered in the W-extended picture where they are denoted by WLM(1,p). As in the rational models, the fusion algebra…
Grothendieck ring and Verlinde-like formula for the W-extended logarithmic minimal model WLM(1,p)
Paul A. Pearce, Jorgen Rasmussen, Philippe Ruelle
We consider the Grothendieck ring of the fusion algebra of the W-extended logarithmic minimal model WLM(1,p). Informally, this is the fusion ring of W-irreducible characters so it…
