Antiferromagnetic order in systems with doublet $S_{\mathrm{tot}}=1/2$ ground states

Sambuddha Sanyal, Argha Banerjee, Kedar Damle +1

We use projector Quantum Monte-Carlo methods to study the $S_{\mathrm{tot}}=1/2$ doublet ground states of two dimensional $S=1/2$ antiferromagnets on a $L\times L$ square lattice with…
