Gate-Tunable Graphene Hall Sensors with High Magnetic Field Sensitivity
Brian T. Schaefer, Lei Wang, Alexander Jarjour +4
Solid-state magnetic field sensors are important to both modern electronics and fundamental materials science. Many types of these sensors maintain high sensitivity only in a limit…
Momentum-Dark Intervalley Exciton in Monolayer Tungsten Diselenide Brightened via Chiral Phonon

Inversion symmetry breaking and three-fold rotation symmetry grant the valley degree of freedom to the robust exciton in monolayer transition metal dichalcogenides (TMDCs), which c…
Effect of Rough Walls on Transport in Mesoscopic He Films
Priya Sharma, Antonio Corcoles, R. G. Bennett +3
The interplay of bulk and boundary scattering is explored in a regime where quantum size effects modify mesoscopic transport in a degenerate Fermi liquid film of He on a rough…
Optical detection and manipulation of spontaneous gyrotropic electronic order in a transition-metal dichalcogenide semimetal
Su-Yang Xu, Qiong Ma, Yang Gao +16
The observation of chirality is ubiquitous in nature. Contrary to intuition, the population of opposite chiralities is surprisingly asymmetric at fundamental levels. Examples range…
Imaging and control of critical spin fluctuations in two-dimensional magnets
Chenhao Jin, Zui Tao, Kaifei Kang +4
Strong spin fluctuations are expected near the thermodynamic critical point of a continuous magnetic phase transition. Such critical spin fluctuations are highly correlated and in…

Moiré superlattices are emerging as a new route for engineering strongly correlated electronic states in two-dimensional van der Waals heterostructures, as recently demonstrated in…
Anharmonicity strongly enhancing thermal interface conductance: A new anharmonic atomistic Green's function formalism
Jinghang Dai, Zhiting Tian
The traditional atomistic Green's function (AGF) was formulated in the harmonic regime, preventing it from capturing the role of anharmonicity in interfacial thermal transport. Inc…
Identifying Higher Order Topology and Fractional Corner Charge Using Entanglement Spectra
Penghao Zhu, Kieran Loehr, Taylor L. Hughes
We study the entanglement spectrum (ES) of two-dimensional -symmetric second-order topological insulators (TIs). We show that some characteristic higher order topological ob…
Dissipation-enabled hydrodynamic conductivity in a tunable bandgap semiconductor
Cheng Tan, Derek Y. H. Ho, Lei Wang +10
Electronic transport in the regime where carrier-carrier collisions are the dominant scattering mechanism has taken on new relevance with the advent of ultraclean two-dimensional m…
Inducing Kondo Screening of Vacancy Magnetic Moments in Graphene with Gating and Local Curvature
Yuhang Jiang, Jinhai Mao, Po-Wei Lo +7
In normal metals, the magnetic-moment of impurity-spins disappears below a characteristic Kondo temperature, TK. This marks the formation of a polarized cloud of conduction band el…
Symmetry-breaking signatures of multiple Majorana zero modes in one-dimensional spin-triplet superconductors
