Phase-space Fisher information of 2D gapped Dirac materials Bolívar, Juan Carlos Nagy, Agnes Romera Gutiérrez, Elvira Phase-space Fisher information Topological phase transitions Dirac materials It is shown that phase-space Fisher information marks topological phase transitions in 2D Dirac gapped materials. The phase-space Fisher information determined for electrons and holes exhibit minimum at the charge neutrality points. Topological quantum numbers are defined to identify different phases utilizing combined information measures. Upper and lower bounds are derived for the phase-space Fisher information. 2020-04-23T11:50:57Z 2020-04-23T11:50:57Z 2019-02-26 journal article Romera, E. (2019). Juan Carlos Bolívar, Ágnes Nagy &.
