Journal ArticleDOI
Extremely efficient terahertz high-harmonic generation in graphene by hot Dirac fermions
Hassan A. Hafez,Sergey Kovalev,Jan-Christoph Deinert,Zoltan Mics,Bertram Green,Nilesh Awari,Nilesh Awari,Min Chen,Semyon Germanskiy,Ulf Lehnert,Jochen Teichert,Zhe Wang,Klaas-Jan Tielrooij,Zhaoyang Liu,Zongping Chen,Akimitsu Narita,Klaus Müllen,Mischa Bonn,Michael Gensch,Dmitry Turchinovich,Dmitry Turchinovich +20 more
TL;DR: Efficient terahertz harmonic generation—challenging but important for ultrahigh-speed optoelectronic technologies—is demonstrated in graphene through a nonlinear process that could potentially be generalized to other materials.
Journal ArticleDOI
Very Large Tunneling Magnetoresistance in Layered Magnetic Semiconductor CrI$_3$
Zhe Wang,Ignacio Gutiérrez-Lezama,Nicolas Ubrig,Martin Kroner,Marco Gibertini,Takashi Taniguchi,Kenji Watanabe,Atac Imamoglu,Enrico Giannini,Alberto F. Morpurgo +9 more
TL;DR: In this article, the authors show that tunneling conduction in the direction perpendicular to the crystalline planes exhibits a magnetoresistance as large as 10, 000 %, which is a new phenomenon that demonstrates the presence of a strong coupling between transport and magnetism in magnetic van der Waals semiconductors.
Journal ArticleDOI
Magnetic Excitations and Continuum of a Possibly Field-Induced Quantum Spin Liquid in α-RuCl_{3}.
Zhe Wang,S. Reschke,D. Hüvonen,Seung-Hwan Do,K.-Y. Choi,Michael Gensch,Urmas Nagel,Toomas Rõõm,Alois Loidl +8 more
TL;DR: Terahertz spectroscopy of quantum spin dynamics in α-RuCl_{3], a system proximate to the Kitaev honeycomb model, as a function of temperature and magnetic field is reported, characterizing the dynamical properties of a possibly field-induced quantum spin liquid.
Journal ArticleDOI
Experimental observation of Bethe strings
Zhe Wang,Zhe Wang,Jianda Wu,Wang Yang,Anup Kumar Bera,Anup Kumar Bera,D. Kamenskyi,A. T. M. Nazmul Islam,Shenglong Xu,Joseph M. Law,Bella Lake,Bella Lake,Congjun Wu,Alois Loidl +13 more
TL;DR: High-resolution terahertz spectroscopy is used to resolve string states in the antiferromagnetic Heisenberg–Ising chain SrCo2V2O8 in strong longitudinal magnetic fields and identifies strings and fractional magnetic excitations that are accurately described by the Bethe ansatz.
Journal ArticleDOI
Determining the phase diagram of atomically thin layered antiferromagnet CrCl$_3$
Zhe Wang,Marco Gibertini,Dumitru Dumcenco,Takashi Taniguchi,Kenji Watanabe,Enrico Giannini,Alberto F. Morpurgo +6 more
TL;DR: In this article, it was shown that in CrCl$_3$ multilayers, the dependence of the tunnelling conductance on applied magnetic field, temperature, and number of layers tracks the evolution of the magnetic state, enabling the magnetic phase diagram of these systems to be determined experimentally.
