Virasoro Symmetry in Neural Networks

Published:Dec 30, 2025 19:00
1 min read
ArXiv

Analysis

This paper presents a novel approach to constructing Neural Network Field Theories (NN-FTs) that exhibit the full Virasoro symmetry, a key feature of 2D Conformal Field Theories (CFTs). The authors achieve this by carefully designing the architecture and parameter distributions of the neural network, enabling the realization of a local stress-energy tensor. This is a significant advancement because it overcomes a common limitation of NN-FTs, which typically lack local conformal symmetry. The paper's construction of a free boson theory, followed by extensions to Majorana fermions and super-Virasoro symmetry, demonstrates the versatility of the approach. The inclusion of numerical simulations to validate the analytical results further strengthens the paper's claims. The extension to boundary NN-FTs is also a notable contribution.

Analysis

This paper explores the connections between holomorphic conformal field theory (CFT) and dualities in 3D topological quantum field theories (TQFTs), extending the concept of level-rank duality.

Condensing specific anyons on these interfaces leads to dualities between TQFTs. The work focuses on the c=24 holomorphic theories classified by Schellekens, uncovering new dualities, some involving non-abelian anyons and non-invertible symmetries. The findings generalize beyond c=24, including a duality between Spin(n^2)_2 and a twisted dihedral group gauge theory. The paper also identifies a sequence of holomorphic CFTs at c=2(k-1) with Spin(k)_2 fusion category symmetry.

Analysis

This paper investigates the thermodynamic stability of a scalar field in an Einstein universe, a simplified cosmological model. The authors calculate the Feynman propagator, a fundamental tool in quantum field theory, to analyze the energy and pressure of the field. The key finding is that conformal coupling (ξ = 1/6) is crucial for stable thermodynamic equilibrium. The paper also suggests that the presence of scalar fields might be necessary for stability in the presence of other types of radiation at high temperatures or large radii.

Analysis

This paper explores the interfaces between gapless quantum phases, particularly those with internal symmetries. It argues that these interfaces, rather than boundaries, provide a more robust way to distinguish between different phases. The key finding is that interfaces between conformal field theories (CFTs) that differ in symmetry charge assignments must flow to non-invertible defects. This offers a new perspective on the interplay between topology and gapless phases, providing a physical indicator for symmetry-enriched criticality.
Reference

Whenever two 1+1d conformal field theories (CFTs) differ in symmetry charge assignments of local operators or twisted sectors, any symmetry-preserving spatial interface between the theories must flow to a non-invertible defect.

Analysis

This paper explores the construction of conformal field theories (CFTs) with central charge c>1 by coupling multiple Virasoro minimal models.

The identification of fixed points with specific symmetry groups (e.g., PSL2(N), Mathieu group) is particularly significant, as it expands the known landscape of CFTs. The paper's rigorous approach and discovery of new fixed points contribute to our understanding of CFTs beyond the standard minimal models.
