Metasurfaces exhibiting spatially asymmetric inner structures have been shown to host
unidirectional scattering effects, benefiting areas where directional control of waves is …

Identifying phase boundaries of interacting systems is one of the key steps to understanding
quantum many-body models. The development of various numerical and analytical methods …

Non-Hermitian physical systems have attracted considerable attention in recent years for
their unique properties around exceptional points (EPs), where the eigenvalues and …

Exceptional points facilitate peculiar dynamics in non-Hermitian systems. Yet, in photonics,
they have mainly been studied in the classical realm. In this work, we reveal the behavior of …

Thermodynamics constrains changes to the energy of a system, both deliberate and
random, via its first and second laws. When the system is not in equilibrium, fluctuation …

Over the past decade, classical optical systems with gain or loss, modeled by non-Hermitian
parity-time symmetric Hamiltonians, have been deeply investigated. Yet, their applicability to …

Multiphoton correlations in linear photonic quantum networks are governed by matrix
permanents. Yet, surprisingly few systematic properties of these crucial algebraic objects are …

Since the realization of quantum systems described by non-Hermitian Hamiltonians with
parity-time (PT) symmetry, interest in non-Hermitian, quantum many-body models has …

We study operator correlations of a spinful Luttinger liquid after introducing a non-Hermitian
interaction quench, yielding supersonic modes and dominant superconducting correlations …

Photonics, as a platform for quantum information processing, has the unique ability to exploit
the qubits temporal degree of freedom. For photonic quantum computing, this can be used to …
