Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The Lagrange multiplier method is applied to study a nonequilibrium steady state with energy flux in the one-dimensional spin-1/2 XX model of a magnetoelectric with the Katsura-Nagaosa-Balatsky mechanism at sufficiently low temperatures. With the help of the Jordan-Wigner transformation, the problem is reduced to that with the Hamiltonian for spinless noninter-acting fermions and can be solved exactly. A number of phase diagrams are plotted, and the dependences of the magnetization, electric polarization, and various susceptibilities on the magnetic and electric fields, as well as on the energy flux, are calculated.
