Reparametrization modes in 2d CFT and the effective theory of stress tensor exchanges
Journal of High Energy Physics, 2021 We study the origin of the recently proposed effective theory of stress tensor exchanges based on reparametrization modes, that has been used to efficiently compute Virasoro identity blocks at large central charge.

Safe Reparametrization of Component-Based WSNs [PDF]
, 2014 Modern Wireless Sensor Networks are moving from singe-purpose custom built solutions towards multi-purpose application hosting platforms. These platforms support multiple concurrent applications managed by multiple actors. Reconfigurable component-models are a viable solution for supporting these scenarios by reducing management and development ...

Virasoro blocks and the reparametrization formalism
Journal of High Energy Physics, 2023 An effective theory designed to compute Virasoro identity blocks at large central charge, expressed in terms of the propagation of a reparametrization/shadow mode between bilocal vertices, was recently put forward.

Time-reparametrization invariances, multithermalization and the Parisi scheme
SciPost Physics Core, 2023 The Parisi scheme for equilibrium and the corresponding slow dynamics with multithermalization - same temperature common to all observables, different temperatures only possible at widely separated timescales – imply one another.

Reparametrization invariance and partial re-summations of the heavy quark expansion
Journal of High Energy Physics, 2018 We extend existing work on reparametrization invariance (RPI) of the heavy-quark expansion (HQE). RPI implies relations between different orders of the HQE.

Chaos and the reparametrization mode on the AdS2 string
Journal of High Energy Physics, 2023 We study the holographic correlators corresponding to scattering of fluctuations of an open string worldsheet with AdS2 geometry. In the out-of-time-order configuration, the correlators display a Lyapunov growth that saturates the chaos bound.

Reparametrization modes, shadow operators, and quantum chaos in higher-dimensional CFTs
Journal of High Energy Physics, 2019 We study two novel approaches to efficiently encoding universal constraints imposed by conformal symmetry, and describe applications to quantum chaos in higher dimensional CFTs.

Reparametrization ghost contribution to superstring multiloop amplitudes
Physical Review D, 1992 We use the sewing procedure in the operator formalism to construct the {ital N}-point {ital g}-loop vertex {ital V}{sub {ital N};{ital g}} for the ({ital b},{ital c}) system in superstring theory. After computing explicitly the lowest picture-changed states, we saturate {ital V}{sub {ital N};{ital g}} with them showing that the reparametrization ghost ...

Optimal affine reparametrization of rational curves
Journal of Symbolic Computation, 2011 Let \({\mathbb K}\) be a characteristic zero field, and let \({\mathcal C}\) be a rational curve in \({\mathbb F}^N\) (\(N\) arbitrary), where \({\mathbb F}\) is the algebraic closure of \({\mathbb K}\). Assume that \({\mathcal C}\) is parametrized by means of a birational parametrization \(\phi(t)\) with coefficients over an algebraic extension ...
