Notes on resummation-based quantum Monte Carlo vis-à-vis sign-problematic Heisenberg models on canonical geometrically frustrated lattices
Nisheeta Desai, Sumiran Pujari
We show here that a direct application of resummation-based quantum Monte Carlo (QMC) -- implemented recently for sign-problem-free SU(2)-symmetric Hamiltonians in the stochastic s…
Punctured-Chern topological invariants for semi-metallic bandstructures
Ankur Das, Eyal Cornfeld, Sumiran Pujari
Topological insulator-based methods underpin the topological classification of gapped bands, including those surrounding semi-metallic nodal defects. However, multiple bands with g…
Decoupling Nuclear Spins via Interaction-Induced Freezing in Nitrogen Vacancy Centers in Diamond
Abhishek Kejriwal, Dasika Shishir, Sumiran Pujari +1
Nitrogen-Vacancy (NV) centers in diamonds provide a room-temperature platform for various emerging quantum technologies, e.g. the long nuclear spin coherence times as potential qua…
