A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Conformal differential operator in embedding space and its applications

Journal of High Energy Physics, 2019
We develop techniques useful for obtaining conformal blocks in embedding space. We construct a unique differential operator in embedding space and use it to construct a function that will be an important ingredient in assembling conformal blocks. We show

Dispersion relation for CFT four-point functions

Journal of High Energy Physics, 2020
We present a dispersion relation in conformal field theory which expresses the four point function as an integral over its single discontinuity. Exploiting the analytic properties of the OPE and crossing symmetry of the correlator, we show that in ...

Wronskian indices and rational conformal field theories

Journal of High Energy Physics, 2021
The classification scheme for rational conformal field theories, given by the Mathur-Mukhi-Sen (MMS) program, identifies a rational conformal field theory by two numbers: (n, l). n is the number of characters of the rational conformal field theory.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

A deformed supersymmetric $$w_{1+\infty }$$ w 1 + ∞ symmetry in the celestial conformal field theory

European Physical Journal C: Particles and Fields, 2022
Abstract By using the K-free complex bosons and the K-free complex fermions, we construct the $$\mathcal {N}\,{=}\,2$$ N = 2 supersymmetric $$W_{\infty }^{K,K}$$ W ∞ K , K algebra which is the matrix generalization of previous $${{\mathcal {N}}}\,{=}\,2$$ N = 2 supersymmetric $$W_{\infty }$$ W ∞ algebra. By twisting this $${{\mathcal {N}}}\,{=}\,2$$ N =

Towards a supersymmetric $w_{1+\infty }$ symmetry in the celestial conformal field theory

Physical Review, 2022
The w1+∞ symmetry algebra appears in the Einstein–Yang–Mills theory, proposed recently by Strominger. In this paper, we derive the supersymmetric w1+∞ symmetry by using the known results on the operator product expansions (OPEs) between the graviton, gravitino, gluon, and gluino in the supersymmetric version of the above theory.

A new handle on three-point coefficients: OPE asymptotics from genus two modular invariance

Journal of High Energy Physics, 2017
We derive an asymptotic formula for operator product expansion coefficients of heavy operators in two dimensional conformal field theory. This follows from modular invariance of the genus two partition function, and generalises the asymptotic formula for

Classifying three-character RCFTs with Wronskian index equalling 0 or 2

Journal of High Energy Physics, 2021
In the modular linear differential equation (MLDE) approach to classifying rational conformal field theories (RCFTs) both the MLDE and the RCFT are identified by a pair of non-negative integers [n,l].
