Metric Options: Counts1 Year3 YearSelecting 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
An operator formalism for bosonization at finite temperature and density is developed. We treat the general case of anyon statistics. The exact n -point correlation functions, satisfying the Kubo–Martin–Schwinger condition, are explicitly constructed. The invariance under both vector and axial transformations allows to introduce two chemical potentials, which give rise to non-vanishing persistent currents. Investigating the exact momentum distribution, we discover anyon condensation in certain range of the statistical parameter, which shows that condensation is not an exclusive prerogative of bosonic systems. As an application of the general formalism, we solve the massless Thirring model at finite temperature, deriving the charge density and the persistent current.
