A theorem on extensive ground state entropy, spin liquidity and some related models
Sumiran Pujari
An exact mechanism is written down to guarantee extensive residual ground state entropy and spin liquidity in spin-1/2 lattice models with bond-dependent couplings. It is based on…

Bilayer Coulomb phase of two dimensional dimer models: Absence of power-law columnar order
Nisheeta Desai, Sumiran Pujari, K. Damle
We study the fully-packed dimer model on the bilayer square lattice with fugacity equal to () for inter-layer (intra-layer) dimers, and intra-layer interaction between n…
