Ferroelectric-assisted charge-transfer plasmons in graphene/CuInP2S6

Yinming Shao, Hae-Yeon Lee, Jin Zhang, Samuel Moore et autres

Abstract Two-dimensional materials and their van der Waals heterostructures provide a versatile platform for novel optoelectronic functionalities. Interfacial charge transfer in such stacks enables high-quality graphene plasmons, but the charge-doping is fixed by work-function differences between constituent layers. Ferroelectric substrates have been …

Colloquium: Semi-Dirac Fermions in Quantum Matter

Bruno Uchoa, Mohamed M. Elsayed, Valeri N. Kotov, Yinming Shao et autres

This article reviews the recent progress on the subject of semi-Dirac fermions, two dimensional quasiparticles that disperse quadratically, as Galilean invariant particles, or linearly, as massless relativistic particles, depending on their direction of motion. These particles exist at a phase boundary set …

Cavity control of multiferroic order in single-layer NiI2

Chongxiao Fan, Emil Viñas Boström, Xinle Cheng, Lukas Grunwald et autres

Abstract Controlling materials through their interactions with electromagnetic vacuum fluctuations is an emergent frontier in material engineering. Although recent experiments have demonstrated dark cavity effects for electronic material phases, like superconductivity, ferroelectricity and charge density waves, a smoking gun experiment for magnetic …

Signatures of quantum chaos in phonon-polariton billiards

Yinan Dong, Felix Liu, Ekrem Demirboga, Andrey Grankin et autres

We use scanning near-field optical microscopy to image hyperbolic phonon polaritons in hexagonal boron nitride (hBN) billiards with integrable and chaotic geometries. In Sinai billiards, we observe irregular mode patterns consistent with quantum scarring, together with an unexpected sensitivity to weak probe …

The path to room-temperature superconductivity: A programmatic approach

Rohit P. Prasankumar, Matthew Julian, Michael Hutcheon, C Heil et autres

Room-temperature superconductivity is arguably the greatest challenge in condensed matter physics, with significant practical and commercial implications if it can be solved. There are no physical laws preventing this from occurring; indeed, superconductivity has been observed in so many different materials under …

Cavity-altered superconductivity

Itai Keren, Tatiana A. Webb, Shuai Zhang, Shuai Zhang et autres

Is it feasible to alter the ground-state properties of a material by engineering its electromagnetic environment? Inspired by theoretical predictions1–12, experimental realizations of such cavity-controlled properties without optical excitation are beginning to emerge13–19. Here we devised and implemented a new platform to …
