-like algebras via the -graded Kac-Moody algebra
Armin Ghazi, Ahmad Moradpouri
The Sugawara construction provides a natural way to construct the Virasoro algebra from a current algebra. It was shown in Ref.~\cite{Ghazi:2025oin} that for the Kac-Moody…

The equivariant Virasoro algebra via alternative Sugawara constructions
Armin Ghazi, Ahmad Moradpouri
In this paper, we study the Kac--Moody algebra and generalize the standard Sugawara construction of the Virasoro algebra to an infinite family of new realizations. In this…

Material and size dependent corrections to conductance quantization in anomalous Hall effect from anomaly inflow
Armin Ghazi, Seyed Akbar Jafari
In quantum anomalous Hall (QAH) systems, the Hall conductance is quantized and the corresponding effective topological theory of the system is the Chern-Simons theory. The conducta…
