All-optical band engineering of gapped Dirac materials

We demonstrate theoretically that the interaction of electrons in gapped Dirac materials (gapped graphene and transition-metal dichalchogenide monolayers) with a strong off-resonant electromagnetic...

From football to physics

Zachary Hulcher was once set on becoming a lawyer. In high school, he took part in mock trials and competed...

Robust Two-Dimensional Electronic Properties in Three-Dimensional Microstructures of Rotationally Stacked Turbostratic Graphene

Nils Richter1,2, Yenny R. Hernandez1,3,4, Sebastian Schweitzer5, June-Seo Kim1,5,6, Ajit Kumar Patra5,7, Jan Englert8, Ingo Lieberwirth3, Andrea Liscio9,10, Vincenzo Palermo9, Xinliang Feng3,11, Andreas Hirsch8,...

General Green’s function formalism for layered systems: Wave function approach

The single-particle Green's function (GF) of mesoscopic structures plays a central role in mesoscopic quantum transport. The recursive GF technique is a standard...

Interaction effects in a chaotic graphene quantum billiard

We investigate the local electronic structure of a Sinai-like, quadrilateral graphene quantum billiard with zigzag and armchair edges using scanning tunneling microscopy (STM)...

Publisher’s Note: Interpenetrating graphene networks: Three-dimensional node-line semimetals with massive negative linear compressibilities [Phys. Rev. B 94, 245422 (2016)]

Publisher's Note: Interpenetrating graphene networks: Three-dimensional node-line semimetals with massive negative linear compressibilities Yangzheng Lin, Zhisheng Zhao, Timothy A. Strobel, and R. E....

Ultrafast Multiphoton Thermionic Photoemission from Graphite

Graphene, a two-dimensional sheet of carbon atoms, is a remarkable material. It is strong, transparent, flexible, and an excellent conductor of electricity. These...

Deviation from the Normal Mode Expansion in a Coupled Graphene-Nanomechanical System

A significant deviation from the normal mode expansion is observed in the optomechanically measured thermal noise of a graphene membrane suspended on a...

Interpenetrating graphene networks: Three-dimensional node-line semimetals with massive negative linear compressibilities

We investigated the stability and mechanical and electronic properties of 15 metastable mixed sp2−sp3 carbon allotropes in the family of interpenetrating graphene networks...

Role of direct exchange and Dzyaloshinskii-Moriya interactions in magnetic properties of graphene derivatives: C_{2} F and C_{2} H

According to Lieb's theorem the ferromagnetic interaction in graphene-based materials with bipartite lattice is a result of disbalance between the number of sites...

Contact-Induced Spin Relaxation in Graphene Nonlocal Spin Valves

We report on a systematic study of contact-induced spin relaxation in gated graphene nonlocal spin valves. We demonstrate the enhancement of the nonlocal...

Entanglement bonanza

Quantum computers promise huge speedups on some computational problems because they harness a strange physical property called entanglement, in which...
