Long-Distance Spin Transport Through a Graphene Quantum Hall Antiferromagnet
Petr Stepanov, Shi Che, Dmitry Shcherbakov +11
Antiferromagnetic insulators (AFMI) are robust against stray fields, and their intrinsic dynamics could enable ultrafast magneto-optics and ultrascaled magnetic information process…
Raman Spectroscopy, Photocatalytic Degradation and Stabilization of Atomically Thin Chromium Triiodide
Dmitry Shcherbakov, Petr Stepanov, Daniel Weber +10
As a 2D ferromagnetic semiconductor with magnetic ordering, atomically thin chromium triiodide is the latest addition to the family of two-dimensional (2D) materials. However, real…
Giant Tunability of Intersubband Transitions and Quantum Hall Quartets in Few-Layer InSe Quantum Wells
Dmitry Shcherbakov, Greyson Voigt, Shahriar Memaran +8
A two-dimensional (2D) quantum electron system is characterized by the quantized energy levels, or subbands, in the out-of-plane direction. Populating higher subbands and controlli…
Distinct magneto-Raman signatures of spin-flip phase transitions in CrI3
Amber McCreary, Thuc T. Mai, Franz G. Utermohlen +16
The discovery of 2-dimensional (2D) materials, such as CrI3, that retain magnetic ordering at monolayer thickness has resulted in a surge of research in 2D magnetism from both pure…
Multistep Methods for Lattice QCD Simulations
Dmitry Shcherbakov, Matthias Ehrhardt
It is well-known that molecular dynamics integrators, which are used for lattice quantum chromodynamics (QCD), suffer from instabilities and possess a rather low order of the accur…
Adapted nested force-gradient integrators: the Schwinger model case
Dmitry Shcherbakov, Matthias Ehrhardt, Jacob Finkenrath +3
We study a novel class of numerical integrators, the adapted nested force-gradient schemes, used within the molecular dynamics step of the Hybrid Monte Carlo (HMC) algorithm. We te…
Force-Gradient Nested Multirate Methods for Hamiltonian System
Dmitry Shcherbakov, Matthias Ehrhardt, Michael Günther +1
Force-gradient decomposition methods are used to improve the energy preservation of symplectic schemes applied to Hamiltonian systems. If the potential is composed of different par…
Light sources with bias tunable spectrum based on van der Waals interface transistors
Hugo Henck, Diego Mauro, Daniil Domaretskiy +13
Light-emitting electronic devices are ubiquitous in key areas of current technology, such as data communications, solid-state lighting, displays, and optical interconnects. Control…
Thickness and twist angle dependent interlayer excitons in metal monochalcogenide heterostructures
Wenkai Zheng, Li Xiang, Felipe de Quesada +18
Interlayer excitons, or bound electron-hole pairs whose constituent quasiparticles are located in distinct stacked semiconducting layers, are being intensively studied in heterobil…
Lessons from -RuCl3 for pursuing quantum spin liquid physics in atomically thin materials
Claudia Ojeda-Aristizabal, Xiaohu Zheng, Changsong Xu +20
Quantum spin liquids can arise from Kitaev magnetic interactions, and exhibit fractionalized excitations with the potential for a topological form of quantum computation. This revi…
