چکیده

In this work, we study non-equilibrium dynamics in Floquet conformal field theories (CFTs) 1+1D, which the driving Hamiltonian involves energy-momentum density spatially modulated by an arbitrary smooth function. This generalizes earlier work was restricted to sine-square deformed type of Hamiltonians, operating within a \mathfrak{sl}_2 ????????2 sub-algebra. Here show remarkably that problem remains soluble generalized case full Virasoro algebra, based on geometrical approach. It is found phase diagram determined stroboscopic trajectories operator evolution. The presence/absence spatial fixed points evolution indicates driven CFT heating/non-heating phase, entanglement entropy grows/oscillates time. Additionally, heating regime further subdivided into multitude phases, with different patterns and distribution density, are characterized number points. Phase transitions between these phases can be achieved simply changing duration application Hamiltonian. %In general, there rich internal structures numbers points, result space. %Interestingly, after each cycle, will shuffle other array, come back original locations p display="inline">p ( p\ge 1 display="inline">p?1 ) cycles. We demonstrate general features concrete examples compare results lattice calculations find remarkable agreement.

Bethe ansatz for deformed WA N − 1 conformal field theories

We propose and investigate the thermodynamic Bethe ansatz equations for the minimal W p models (associated with the AN−1 Lie algebra) perturbed by the least (ZN invariant) primary field ΦN . Our results reproduce the expected ultraviolet and infrared regimes. In particular for the positive sign of the perturbation our equations describe the behaviour of the ground state flowing from the W p mod...

Conformal Field Theories

All unitary Rational Conformal Field Theories (RCFT) are conjectured to be related to unitary coset Conformal Field Theories, i.e., gauged Wess-ZuminoWitten (WZW) models with compact gauge groups. In this paper we use subfactor theory and ideas of algebraic quantum field theory to approach coset Conformal Field Theories. Two conjectures are formulated and their consequences are discussed. Some ...

Hybrid conformal field theories

We describe a class of (2,2) superconformal field theories obtained by fibering a Landau-Ginzburg orbifold CFT over a compact Kähler base manifold. While such models are naturally obtained as phases in a gauged linear sigma model, our construction is independent of such an embedding. We discuss the general properties of such theories and present a technique to study the massless spectrum of the...

Biharmonic Conformal Field Theories

The main result of this paper is the construction of a conformally covariant operator in two dimensions acting on scalar fields and containing fourth order derivatives. In this way it is possible to derive a class of Lagrangians invariant under conformal transformations. They define conformal field theories satisfying equations of the biharmonic type. Two kinds of these biharmonic field theorie...

Logarithmic Conformal Field Theories

We analyse the SU(2) k WZNW models beyond the integrable representations and in particular the case of SU(2) 0. We find that these are good examples of logarithmic conformal field theories as indecomposable representations are naturally produced in the fusion of discrete irreducible representations. We also find extra, chiral and non-chiral, multiplet structure in the theory. The chiral fields,...
