Length and torsion dependence of thermal conductivity in twisted graphene nanoribbons

本文通过精确几何参数（twist和writhe）和分子动力学模拟，揭示扭转石墨烯纳米带的热导率不能仅由初始扭转圈数描述，而需由初始圈数和初始扭转密度两个参数共同刻画。

Electron and phonon transport in twisted graphene nanoribbons

We theoretically study the electrical, thermal and thermoelectric transport properties of graphene nanoribbons under torsional deformations. The modelling follows a nonequilibrium Green's function approach in the ballistic transport regime, describing the electrical and phononic properties through \textit{ab-initio} density functional theory and empirical interatomic potentials, respectively. We consider two different types of deformations, a continuous twist of a given angle applied to the nanoribbon, and two consecutive twists applied in opposite angular directions. The numerical results are…

Chiral kinetic theory of anomalous transport induced by torsion

In Weyl semimetals subjected to torsion, there are two different kinds of chirality: i) the (coordinate-space) shape of the twisted crystal is chiral, and ii) the momentum space contains chiral quasi-particles. Here we construct a general kinetic theory of anomalous transport using the phase space (coordinate and momentum spaces combined) Berry curvature induced by torsion in Weyl systems. We describe how torsion generates the chiral chemical potential, and thus leads to the Chiral Magnetic Effect (CME) in the presence of a background magnetic field. We propose to measure the CME current induc…

Crystallographic bulk-edge correspondence: glide reflections and twisted mod 2 indices

A 2-torsion topological phase exists for Hamiltonians symmetric under the wallpaper group with glide reflection symmetry, corresponding to the unorientable cycle of the Klein bottle fundamental domain. We prove a mod 2 twisted Toeplitz index theorem, which implies a bulk-edge correspondence between this bulk phase and the exotic topological zero modes that it acquires along a boundary glide axis.

当无序介观环中的无自旋费米子系统在由随机势驱动的非均匀位形（Anderson绝缘体）和由排斥相互作用驱动的均匀位形（莫特绝缘体）之间变得不稳定时，持续电流可以增加几个数量级。这一点可以用密度矩阵重整化群算法研究扭曲边界条件下基态能量的变化来说明。
