Abstract
We discuss the thermal entanglement close to a quantum phase transition by analyzing the concurrence for one dimensional models in the quantum Ising universality class. We demonstrate that the entanglement sensitivity to thermal and to quantum fluctuations obeys universal --scaling behaviour. We show that the entanglement, together with its criticality, exhibits a peculiar universal crossover behaviour.
