Mapping of Fermionic Lattice Models for Ising Solvers
Lakshya Nagpal, Aditya Kumar, S. R. Hassan
We present an end-to-end, symmetry-aware pipeline that converts interacting fermionic and quantum-spin models into annealer-ready QUBOs while preserving low-energy physics. The wor…

Positive scalar curvature and exotic structures on simply connected four manifolds
Aditya Kumar, Balarka Sen
We address Gromov's band width inequality and Rosenberg's -stability conjecture for simply connected smooth four manifolds. Both results are known to be false in dimension 4 d…
