“…Based on cavity-magnon polaritons, quantum memories have been realized [25], remote coherent coupling between two magnons has been proposed [26] and observed [27]. At the same time, coupled cavitymagnon polaritons are attractive systems for exploring non-Hermitian physics [15,28,29], because of their easy reconfiguration, flexible tunability, and especially the strong compatibility with microwave [30,31], optics [32][33][34][35], as well as mechanical resonators [36,37].…”

As the counterpart of PT symmetry, abundant phenomena and potential applications of anti-PT symmetry have been predicted or demonstrated theoretically. However, experimental realization of the coupling required in the anti-PT symmetry is difficult. Here, by coupling two YIG spheres to a microwave cavity, the large cavity dissipation rate makes the magnons coupled dissipatively with each other, thereby obeying a two-dimensional anti-PT Hamiltonian. In terms of the magnon-readout method, a new method adopted here, we demonstrate the validity of our method in constructing an anti-PT system and present the counterintuitive level attraction process. Our work provides a new platform to explore the anti-PT symmetry properties and paves the way to study multi-magnoncavity-polariton systems.

“…[20][21][22][23] One of the best known monolayer superconductors, NbSe 2 , is a conventional s-wave superconductor in the monolayer limit. [24][25][26] Despite its conventional nature, recent results point toward the proximity to potential correlated ground states, [27][28][29][30] suggesting that other related materials would be outstanding candidates for monolayer unconventional superconductors.…”

Unconventional superconductors represent one of the fundamental directions in modern quantum materials research. In particular, nodal superconductors are known to appear naturally in strongly correlated systems, including cuprate superconductors and heavy‐fermion systems. Van der Waals materials hosting superconducting states are well known, yet nodal monolayer van der Waals superconductors have remained elusive. Here, using low‐temperature scanning tunneling microscopy (STM) and spectroscopy (STS) experiments, we show that pristine monolayer 1H‐TaS2 realizes a nodal superconducting state. By including non‐magnetic disorder, we drive the nodal superconducting state to a conventional gapped s‐wave state. Furthermore, we observe the emergence of many‐body excitations close to the gap edge, signalling a potential unconventional pairing mechanism. Our results demonstrate the emergence of nodal superconductivity in a van der Waals monolayer, providing a building block for van der Waals heterostructures exploiting unconventional superconducting states.This article is protected by copyright.
