We show that the recently introduced ModMax theory of electrodynamics and its Born-Infeld-like generalization are related by a flow equation driven quadratic combination stress-energy tensors.

In this Letter, we introduce a one-parameter deformation of two-dimensional quantum field theories generated by nonanalytic operator that call Root-TT[over ¯]. For conformal theory, the coincides with square root TT[over ¯] operator. More generally, is defined so classically it marginal and generates flow commutes flow. Intriguingly, closely related to ModMax theory recently constructed Bandos, Lechner, Sorokin, Townsend.
A bstract We generalize the auxiliary field deformations of principal chiral model (PCM) introduced in [1] and [2] to sigma models whose target manifolds are symmetric or semi-symmetric spaces, including a Wess-Zumino term latter case. This gives rise new infinite family classically integrable ℤ 2 4 coset form which interest applications integrability worldsheet string theory holography. demonstrate that every this class admits zero-curvature representation for its equations motion by...

Given a model for self-dual nonlinear electrodynamics in four spacetime dimensions, any deformation of this theory which is constructed from the duality-invariant energy-momentum tensor preserves duality invariance. In work we present new proofs known result and also establish previously unknown converse: parametrized family Lagrangians, all an Abelian field strength ${F}_{\ensuremath{\mu}\ensuremath{\nu}}$ but not its derivatives, related by generalized stress flow, sense make precise. We...

Creating sophisticated machine learning models to comprehend interactions between individuals can lead more intuitive user experiences for interactive systems like Amazon Alexa. Beyond basic indicators such as voice modulation and eye movement, a person's combined audio-visual expressions—including vocal intonation facial gestures—act subtle cues reflecting the level of engagement in conversation. This research explores advanced deep techniques detection expressions through data. Initially,...
