Spin-1/2 Heisenberg ladder: variation of entanglement and fidelity measures close to quantum critical points
Amit Tribedi, Indrani Bose
We consider a two-chain, spin-1/2 antiferromagnetic Heisenberg spin ladder in an external magnetic field H. The spin ladder is known to undergo second order quantum phase transitio…

Entanglement and fidelity signatures of quantum phase transitions in spin liquid models
Amit Tribedi, Indrani Bose
We consider a spin ladder model which is known to have matrix product states as exact ground states with spin liquid characteristics. The model has two critical-point transitions a…
