Coulomb drag in double layer graphene systems separated by an h-BN interlayer allows probing of the electron-electron interactions in the effective limit of zero layer separation. Although these interactions can be influenced by plasmons, phonons and exchange and correlation effects, these excitations have never been studied altogether, missing the effects of their coupling on the drag physics. Here we study theoretically the effects of these quasiparticles and their coupling, including also the effects of the electronic exchange and correlation, and demonstrate that the drag resistivity can attain a maximum value at room temperature and beyond, where hybridized plasmon-phonon modes contribute significantly. In particular, the hybridization of the plasmons with the hyperbolic phonons of h-BN, confined within the reststrahlen bands, enhance the drag resistivity. This study paves the way for the exploration of novel many-body physics phenomena in systems coupled through emerging 2D hyperbolic materials.

由h-BN中间层分隔的双层石墨烯系统中的库仑阻力允许在零层分隔的有效极限内探测电子-电子相互作用。尽管这些相互作用会受到等离激元，声子以及交换和相关效应的影响，但这些激发从未被完全研究过，缺少了它们耦合对拖曳物理的影响。在这里，我们从理论上研究了这些准粒子及其耦合的影响，包括电子交换和相关的影响，并证明了在室温及更高温度下（在杂化等离子体激元-声子模式中起重要作用），抗阻性可以达到最大值。尤其是，等离激元与h-BN的双曲声子的杂交，被限制在reststrahlen带内，增强抗阻力性。这项研究为探索通过新兴的2D双曲材料耦合的系统中的新颖多体物理现象铺平了道路。
