Freudenthal duality in conformal field theory
Journal of High Energy PhysicsRotational Freudenthal duality (RFD) relates two extremal Kerr-Newman (KN) black holes (BHs) with different angular momenta and electric-magnetic charges, but with the same Bekenstein-Hawking entropy.

Localized quench in 1+1 conformal field theory
EPJ Web of Conferences, 2016 We study the boundary dual of AdS3 spacetime with a point particle. Particles in AdS3 generate topological defects, which allows to formulate the geodesic image method for boundary correlators.

Conformal Field Theories in Fractional Dimensions [PDF]
Physical Review Letters, 2014 We study the conformal bootstrap in fractional space-time dimensions, obtaining rigorous bounds on operator dimensions. Our results show strong evidence that there is a family of unitary CFTs connecting the 2D Ising model, the 3D Ising model, and the free scalar theory in 4D. We give numerical predictions for the leading operator dimensions and central

Entanglement entropy in conformal quantum mechanics
Journal of High Energy Physics, 2023 We consider sets of states in conformal quantum mechanics associated to generators of time evolution whose orbits cover different regions of the time domain.

Spin clusters and conformal field theory [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2013 We study numerically the fractal dimensions and the bulk three-point connectivity for the spin clusters of the Q-state Potts model in two dimensions with $1\leq Q\leq 4$. We check that the usually invoked correspondence between FK clusters and spin clusters works at the level of fractal dimensions.

Quark-antiquark potential in defect conformal field theory
Journal of High Energy Physics, 2017 We consider antiparallel Wilson lines in N $$ \mathcal{N} $$ = 4 super Yang-Mills in the presence of a codimension-1 defect. We compute the Wilson lines’ expectation value both at weak coupling, in the gauge theory, and at strong coupling, by finding the

Boundary Conformal Field Theory [PDF]
, 2006 Boundary conformal field theory (BCFT) is simply the study of conformal field theory (CFT) in domains with a boundary. It gains its significance because, in some ways, it is mathematically simpler: the algebraic and geometric structures of CFT appear in a more straightforward manner; and because it has important applications: in string theory in the ...

Minimal lectures on two-dimensional conformal field theory
SciPost Physics Lecture Notes, 2018 We provide a brief but self-contained review of conformal field theory on the Riemann sphere. We first introduce general axioms such as local conformal invariance, and derive Ward identities and BPZ equations.

Spontaneous conformal symmetry breaking in fishnet CFT
Physics Letters B, 2020 Quantum field theories with exact but spontaneously broken conformal invariance have an intriguing feature: their vacuum energy (cosmological constant) is equal to zero. Up to now, the only known ultraviolet complete theories where conformal symmetry can

Loops in AdS from conformal field theory
Journal of High Energy Physics, 2017 We propose and demonstrate a new use for conformal field theory (CFT) crossing equations in the context of AdS/CFT: the computation of loop amplitudes in AdS, dual to non-planar correlators in holographic CFTs. Loops in AdS are largely unexplored, mostly
