    "abstract": "We present a finite-size scaling analysis of the entanglement in a\ntwo-dimensional arrays of quantum dots modeled by the Hubbard Hamiltonian on a\ntriangular lattice. Using multistage block renormalization group approach, we\nhave found that there is an abrupt jump of the entanglement when a first-order\nquantum phase transition occurs. At the critical point, the entanglement is\nconstant, independent of the block size.",
