Efficient Representation of multicategorical local Hilbert spaces: nonlinear Restricted Boltzmann Machines to Kolmogorov-Arnold Networks
Abhiroop Lahiri
Neural network quantum states (NQS) for representing spin- systems are typically built from Multi-Layer Perceptrons (MLPs) with binary visible variables, in which the…

Loss of classicality in alternating spin-/spin- chain, in the presence of next-neighbor couplings and Dzyaloshinskii-Moriya interactions
Abhiroop Lahiri, Swapan K Pati
We have considered and alternating Heisenberg spin chain with nearest-neighbor (), next-nearest neighbor () antiferromagnetic couplings along with z-component of the Dzya…

Signatures of nonlinear magnetoelectricity in second harmonic spectra of SU(2) symmetry broken quantum many-body systems
Abhiroop Lahiri, Swapan K. Pati
Quantum mechanical perturbative expressions for second order dynamical magnetoelectric (ME) susceptibilities have been derived and calculated for a small molecular system using the…
