Exact columnar dimer ground state and quantum phase transitions in a frustrated coupled spin ladder model
Manas Ranjan Mahapatra, Rakesh Kumar
We study a spin-half frustrated coupled ladder system, in which ladders with leg, rung, and diagonal interactions are linked via nearest-neighbor coupling. By introducing a leg-sym…

Exact staggered dimer ground state and its stability in a two-dimensional magnet
Manas Ranjan Mahapatra, Rakesh Kumar
Finding an exact solution for a realistic interacting quantum many-body problem is often challenging. There are only a few problems where an exact solution can be found, usually in…
