Generalization of Modular Spread Complexity for Non-Hermitian Density Matrices
Aneek Jana, Maitri Ganguli
In this work we generalize the concept of modular spread complexity to the cases where the reduced density matrix is non-Hermitian. This notion of complexity and associated Lanczos…

Floquet engineering of topological semimetals with bicircularly polarized light
Maitri Ganguli, Aneek Jana, Awadhesh Narayan
We study the effect of illumination of bicircularly polarized light (BCL) on topological semimetals, namely multifold fermion and line-node semimetals. We demonstrate, by means of…

State Dependent Spread Complexity Dynamics in Many-Body Localization Transition
Maitri Ganguli, Aneek Jana
We characterize the Many-Body Localization (MBL) phase transition using the dynamics of spread complexity and inverse participation ratio in the Krylov space starting from differen…
