Switchable giant room-temperature nonlinear Hall effect in Bilayer Graphene
Margherita Melegari, Ignacio Gutiérrez-Lezama, Justin C. W. Song +1
Utilizing quantum second-order nonlinear transport for practical junction-free devices require materials with large and tunable nonlinearites at room temperature -- a current mater…
Layer photovoltaic effect in van der Waals heterostructures
Oles Matsyshyn, Ying Xiong, Arpit Arora +1
We argue that the layer electric polarization of noncentrosymmetric layered heterostructures can be generically controlled by light yielding a layer photovoltaic effect (LPE). The…
The Fermi-Dirac staircase occupation of Floquet bands and current rectification inside the optical gap of metals: a rigorous perspective
Oles Matsyshyn, Justin C. W. Song, Inti Sodemann Villadiego +1
We consider a model of a Bloch band subjected to an oscillating electric field and coupled to a featureless fermionic heat bath, which can be solved exactly. We demonstrate rigorou…
Photocurrent as a multi-physics diagnostic of quantum materials
Qiong Ma, Roshan Krishna Kumar, Su-Yang Xu +2
The photoexcitation life-cycle from incident photon (and creation of photoexcited electron hole pair) to ultimate extraction of electrical current is a complex multi-physics proces…
Anomalous skew-scattering nonlinear Hall effect and chiral photocurrents in {\it PT}-symmetric antiferromagnets
Da Ma, Arpit Arora, Giovanni Vignale +1
Berry curvature and skew-scattering play central roles in determining both the linear and nonlinear anomalous Hall effects. Yet in {\it PT}-symmetric antiferromagnetic metals, Hall…
The Berry dipole photovoltaic demon and the thermodynamics of photo-current generation within the optical gap of metals
Li-kun Shi, Oles Matsyshyn, Justin C. W. Song +1
We dismantle the previously held misconception that it is impossible for bulk rectification mechanisms to induce a net DC electric current when the frequency of the impinging radia…
