Recent progresses in the development of graphene and other two-dimensional (2D) electronic systems have sparked renewed interest in the field of strong interlayer interactions and corresponding novel quantum phases. In particular, the highly tunable electronic properties of constituent 2D layers, together with the accessibility of ultra-small interlayer separation, enable the investigation of the drag effect in previously inaccessible strong-coupling regimes.<\/p>\n<p style=\"font-weight: 400;\">In this talk, I will present our recent work on the interlayer drag experiments in several graphene-based electronic double-layer systems, to reveal a fingerprint feature of drag effect between massless and massive fermions, to discover a new type of quantum interference effect in inter-layer Coulomb drag, and to demonstrate a giant and highly-tunable supercurrent drag effect. Our findings establish a novel platform, i.e., electronic double-layer systems, to exploit novel inter-layer quantum effects, and offer unforeseen opportunities for new-principle electronic devices.<\/p>\n<p>\u00a0<\/p>\n<h4>Curriculum Vitae\uff1a<\/h4>\n<h6 style=\"font-weight: 400;\"><strong style=\"font-weight: var(--wp--custom--font-weight--medium);\">Education:<\/strong><\/h6>\n<p style=\"font-weight: 400;\">Ph.D. in Physics\u00a0\u00a0University of Science and Technology of China\u00a0\u00a0\u00a0\u00a0\u00a0\u00a007\/2002<\/p>\n<h6 style=\"font-weight: 400;\"><strong style=\"font-weight: var(--wp--custom--font-weight--medium);\">Employment:<\/strong><\/h6>\n<p style=\"font-weight: 400;\">University of Science and Technology of China\u00a0\u00a0\u00a0\u00a0Professor\u00a0\u00a0Department of Physics\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a008\/ 2007 &#8211; Current<\/p>\n<h6 class=\"texts\"><strong>Research Interests:<\/strong><\/h6>\n<p><span lang=\"EN-US\">Low-dimensional Quantum Matter Physics<\/span><\/p>\n<p style=\"font-weight: 400;\">\u00a0<\/p>\n<h6 style=\"font-weight: 400;\"><strong style=\"font-weight: var(--wp--custom--font-weight--medium);\">Selective Recent Publications (see a full publication list at http:\/\/staff.ustc.edu.cn\/~cgzeng\/publications.html):<\/strong><\/h6>\n<ul>\n<li style=\"font-weight: 400;\">Ran Tao, Lin Li*, Hong-Yi Xie*, Xiaodong Fan, Linhai Guo, Lijun Zhu, Yuedong Yan, Zhenyu Zhang, and\u00a0<u>Changgan Zeng*<\/u>, \u201cJosephson\u2013Coulomb drag effect between graphene and a LaAlO<sub>3<\/sub>\/SrTiO<sub>3<\/sub>\u00a0superconductor\u201d, Nat.
