Bootstrapping smooth conformal defects in Chern-Simons-matter theories
The expectation value of a smooth conformal line defect in a CFT is a conformal invariant functional of its path in space-time. For example, in large N holographic theories, these fundamental observables are dual to the open-string partition function in Ad ...
New York2024Exact quantum conformal symmetry, its spontaneous breakdown, and gravitational Weyl anomaly
The classical Lagrangian of the Standard Model enjoys the symmetry of the full conformal group if the mass of the Higgs boson is put to zero. This is a hint that conformal symmetry may play a fundamental role in the ultimate theory describing nature. The o ...
AMER PHYSICAL SOC2023From kirigami to hydrogels: a tutorial on designing conformally transformable surfaces
Tian Chen, Yingying Ren, Yue Wang
Elastic surfaces that morph between multiple geometrical configurations are of significant engineering value, with applications ranging from the deployment of space-based PV arrays, the erection of temporary shelters, and the realization of flexible displa ...
2022Is a Single Conformer Sufficient to Describe the Reorganization Energy of Amorphous Organic Transport Materials?
Iwona Swiderska, Kun-Han Lin, Jacob Terence Blaskovits, Raimon Fabregat I De Aguilar-Amat, Hélène Wu
The reorganization energy (lambda), which quantifies the structural rearrangement of a molecule when accommodating a charge, is a key parameter in the evaluation of charge mobility in molecular solids. However, it is unclear how lambda is influenced by con ...
AMER CHEMICAL SOC2021Bootstrapping mixed correlators in N=4 super Yang-Mills
Andrea Manenti, Alessandro Vichi
We perform a numerical bootstrap study of the mixed correlator system containing the half-BPS operators of dimension two and three in N = 4 Super Yang-Mills. This setup improves on previous works in the literature that only considered single correlators of ...
SPRINGER2021Bootstrapping superconformal field theories in four dimensions
The conformal bootstrap is a non-perturbative technique designed to study conformal field theories using only first principles, such as unitarity, crossing symmetry and the existence of an Operator Product Expansion. In this thesis we discuss an applicatio ...
EPFL2020Thermal CFTs in momentum space
We study some aspects of conformal field theories at finite temperature in momentum space. We provide a formula for the Fourier transform of a thermal conformal block and study its analytic properties. In particular we show that the Fourier transform vanis ...
SPRINGER2020Harmonic analysis and mean field theory
We review some aspects of harmonic analysis for the Euclidean conformal group, including conformally-invariant pairings, the Plancherel measure, and the shadow transform. We introduce two efficient methods for computing these quantities: one based on weigh ...
Springer2019A structural test for the conformal invariance of the critical 3d Ising model
How can a renormalization group fixed point be scale invariant without being conformal? Polchinski (1988) showed that this may happen if the theory contains a virial current a non-conserved vector operator of dimension exactly (d - 1), whose divergence exp ...
Springer2019Computational Design of Auxetic Shells
Recent advances in material science and digital fabrication provide promising opportunities for product design, mechanical and biomedical engineering, robotics, architecture, art, and science. Engineered materials and personalized fabrication are revolutio ...
