Modular differential equations with movable poles and admissible RCFT characters (2023)
Journal Article
Das, A., Gowdigere, C. N., Mukhi, S., & Santara, J. (2023). Modular differential equations with movable poles and admissible RCFT characters. Journal of High Energy Physics, 2023(12), Article 143. https://doi.org/10.1007/jhep12%282023%29143

Studies of modular linear differential equations (MLDE) for the classification of rational CFT characters have been limited to the case where the coefficient functions (in monic form) have no poles, or poles at special points of moduli space. Here we... Read More about Modular differential equations with movable poles and admissible RCFT characters.

Higher-form symmetries, anomalous magnetohydrodynamics, and holography (2023)
Journal Article
Das, A., Gregory, R., & Iqbal, N. (2023). Higher-form symmetries, anomalous magnetohydrodynamics, and holography. SciPost Physics, 14(6), Article 163. https://doi.org/10.21468/scipostphys.14.6.163

In U ( 1 ) Abelian gauge theory coupled to fermions, the non-conservation of the axial current due to the chiral anomaly is given by a dynamical operator F μ ν ~ F μ ν constructed from the field-strength tensor. We attempt to describe this physics in... Read More about Higher-form symmetries, anomalous magnetohydrodynamics, and holography.

Meromorphic cosets and the classification of three-character CFT (2023)
Journal Article
Das, A., Gowdigere, C. N., & Mukhi, S. (2023). Meromorphic cosets and the classification of three-character CFT. Journal of High Energy Physics, 2023(3), Article 23 (2023). https://doi.org/10.1007/jhep03%282023%29023

We investigate the admissible vector-valued modular forms having three independent characters and vanishing Wronskian index and determine which ones correspond to genuine 2d conformal field theories. This is done by finding bilinear coset-type relati... Read More about Meromorphic cosets and the classification of three-character CFT.

New meromorphic CFTs from cosets (2022)
Journal Article
Das, A., Gowdigere, C. N., & Mukhi, S. (2022). New meromorphic CFTs from cosets. Journal of High Energy Physics, 2022(7), Article 152. https://doi.org/10.1007/jhep07%282022%29152

In recent years it has been understood that new rational CFTs can be discovered by applying the coset construction to meromorphic CFTs. Here we turn this approach around and show that the coset construction, together with the classification of meromo... Read More about New meromorphic CFTs from cosets.

Classifying three-character RCFTs with Wronskian Index equalling 0 or 2 (2021)
Journal Article
Das, A., Gowdigere, C. N., & Santara, J. (2021). Classifying three-character RCFTs with Wronskian Index equalling 0 or 2. Journal of High Energy Physics, 2021, Article 195. https://doi.org/10.1007/jhep11%282021%29195

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]. n is the number of characters of the RCFT as well...

Wronskian indices and rational conformal field theories (2021)
Journal Article
Das, A., Gowdigere, C. N., & Santara, J. (2021). Wronskian indices and rational conformal field theories. Journal of High Energy Physics, 2021(4), Article 294. https://doi.org/10.1007/jhep04%282021%29294

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. T... Read More about Wronskian indices and rational conformal field theories.
