Quantum dynamics in sine-square deformed conformal field theory: Quench from uniform to nonuniform conformal field theory [PDF]

open access: yesPhysical review B, 2018
In this work, motivated by the sine-square deformation (SSD) for (1+1)-dimensional quantum critical systems, we study the non-equilibrium quantum dynamics of a conformal field theory (CFT) with SSD, which was recently proposed to have continuous energy ...

Energy Momentum Tensor and Marginal Deformations in Open String Field Theory [PDF]

open access: yes, 2004
Marginal boundary deformations in a two dimensional conformal field theory correspond to a family of classical solutions of the equations of motion of open string field theory.

Eigenstate thermalization hypothesis in conformal field theory [PDF]

open access: yes, 2016
We investigate the eigenstate thermalization hypothesis (ETH) in d  +  1 dimensional conformal field theories by studying the reduced density matrices in energy eigenstates.

Entanglement Hamiltonian evolution during thermalization in conformal field theory [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2018
In this work, we study the time evolution of the entanglement Hamiltonian during the process of thermalization in a (1+1)-dimensional conformal field theory (CFT) after a quantum quench from a special class of initial states. In particular, we focus on a

AdS field theory from conformal field theory [PDF]

open access: yesJournal of High Energy Physics, 2013
Abstract We provide necessary and sufficient conditions for a Conformal Field Theory to have a description in terms of a perturbative Effective Field Theory in AdS. The first two conditions are well-known: the existence of a perturbative ‘1/N ’ expansion and an approximate Fock space of states generated by a finite number of low ...

Note on Weyl versus conformal invariance in field theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
It was argued recently that conformal invariance in flat spacetime implies Weyl invariance in a general curved background for unitary theories and possible anomalies in the Weyl variation of scalar operators are identified.

Boundary conformal field theory at large charge

open access: yesJournal of High Energy Physics, 2021
We study operators with large internal charge in boundary conformal field theories (BCFTs) with internal symmetries. Using the state-operator correspondence and the existence of a macroscopic limit, we find a non-trivial relation between the scaling ...

Conformal Field Theory for Inhomogeneous One-dimensional Quantum Systems: the Example of Non-Interacting Fermi Gases [PDF]

open access: yes, 2016
Conformal field theory (CFT) has been extremely successful in describing large-scale universal effects in one-dimensional (1D) systems at quantum critical points. Unfortunately, its applicability in condensed matter physics has been limited to situations

Conformal Transformations in Metric-Affine Gravity and Ghosts [PDF]

open access: yes, 2012
Conformal transformations play a widespread role in gravity theories in regard to their cosmological and other implications. In the pure metric theory of gravity, conformal transformations change the frame to a new one wherein one obtains a conformal ...
