    "abstract": "Maximally entangled mixed states are those states that, for a given\nmixedness, achieve the greatest possible entanglement. For two-qubit systems\nand for various combinations of entanglement and mixedness measures, the form\nof the corresponding maximally entangled mixed states is determined primarily\nanalytically. As measures of entanglement, we consider entanglement of\nformation, relative entropy of entanglement, and negativity; as measures of\nmixedness, we consider linear and von Neumann entropies. We show that the forms\nof the maximally entangled mixed states can vary with the combination of\n(entanglement and mixedness) measures chosen. Moreover, for certain\ncombinations, the forms of the maximally entangled mixed states can change\ndiscontinuously at a specific value of the entropy.",
