The concept of non-Hermitian physics has inspired numerous intriguing phenomena in
classical wave systems. By introducing judicious arrangements of gain and loss media, non …

Integrated photonics will play a key role in quantum systems as they grow from few-qubit
prototypes to tens of thousands of qubits. The underlying optical quantum technologies can …

Dissipation in mechanics, optics, acoustics, and electronic circuits is nowadays recognized
to be not always detrimental but can be exploited to achieve non-Hermitian topological …

We propose an experimentally realizable nonreciprocal magnonic device at the single-
magnon level by exploiting magnon blockade in a magnon-based hybrid system. The …

Non-Hermitian Hamiltonians provide an alternative perspective on the dynamics of quantum
and classical systems coupled non-conservatively to an environment. Once primarily an …

Generation of entanglement between spatially separated macroscopic systems enables
quantum networks and fundamental tests of quantum theory. Here, we propose a scheme to …

Symmetry plays a fundamentally important role in physics. In this work, we find a
conservation law, S†(H c†) S (H c)= I, which is valid for any non-Hermitian scattering center …

We show how to enhance the detection sensitivity of magnon Kerr nonlinearity (MKN) in
cavity magnonics. The considered cavity-magnon system consists of a three-dimensional …

Elastic metamaterial, an engineered artificial material, has received much attention in
physics and engineering communities due to its functional properties unavailable in natural …
