文摘

•: The geometric quantum discord (GQD) of a two qubits system is investigated.
•: The behaviors of GQD under the asymmetry environments are displayed and discussed.
•: The revival phenomenon is depressed with increasing temperature pan id="mmlsi51" class="mathmlsrc">pan class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0378437116301182&_mathId=si51.gif&_user=111111111&_pii=S0378437116301182&_rdoc=1&_issn=03784371&md5=3055fdbe2cd8ef126e0fe5d43bf54b67" title="Click to view the MathML source">Tpan>pan class="mathContainer hidden">pan class="mathCode"> $T$ pan>pan>pan>.
