  author={T. T. Sergeev and Alexander A. Zyablovsky and Evgeny S. Andrianov and Yuriy E. Lozovik},
Exceptional point (EP) is a spectral singularity in non-Hermitian systems. The passing over the EP leads to a phase transition, which endows the system with unconventional features that find a wide range of applications. However, the need of using the dissipation and amplification limits the possible applications of systems with the EP. In this work, the concept of phase transitions at the EP is expanded to Hermitian systems that are free from dissipation and amplification. It is considered a…

Universal Critical Behaviours in Non-Hermitian Phase Transitions

This work proves that the non-degenerate steady state of a non-Hermitian quantum many body system is a universal function of the first derivative of the steady state energy with respect to the control parameter, and reveals that quantum entanglement in non- hermitian phase transition point presents universal scaling behaviors with critical exponents being (1 − 1/p).

Parametric instability of optical non-Hermitian systems near the exceptional point

It is shown that it is possible to increase the mode amplitudes without increasing the power of the signal, which enables compensation for losses in dissipative systems and opens a wide range of applications in optics, plasmonics, and optoelectronics, in which loss is an inevitable problem and plays a crucial role.

Enhanced sensitivity at higher-order exceptional points

Higher-order exceptional points are observed in a coupled cavity arrangement—specifically, a ternary, parity–time-symmetric photonic laser molecule—with a carefully tailored gain–loss distribution and it is found that the frequency response follows a cube-root dependence on induced perturbations in the refractive index.

Observation of the exceptional-point-enhanced Sagnac effect

A precisely controllable integrated optical gyroscope based on stimulated Brillouin scattering is used to study non-Hermitian physics and nonlinear optics in high-quality-factor microresonators, revealing a four-fold enhancement of the Sagnac scale factor near exceptional points.

A phonon laser operating at an exceptional point

Non-Hermitian physical systems have attracted considerable attention lately for their unconventional behaviour around exceptional points (EPs)—spectral singularities at which eigenvalues and

Higher-order exceptional point in a cavity magnonics system

We propose to realize the pseudo-Hermiticity in a cavity magnonics system consisting of the Kittel modes in two small yttrium-iron-garnet spheres coupled to a microwave cavity mode. The effective

Observation of a non-Hermitian phase transition in an optical quantum gas

A non-Hermitian phase transition of a photon Bose-Einstein condensation to a dissipative phase characterized by a biexponential decay of the condensate’s second-order coherence is experimentally demonstrated.

Exceptional points in optics and photonics

The topic of exceptional points in photonics is reviewed and some of the possible exotic behavior that might be expected from engineering such systems are explored, as well as new angle of utilizing gain and loss as new degrees of freedom, in stark contrast with the traditional approach of avoiding these elements.

A new type of non-Hermitian phase transition in open systems far from thermal equilibrium

A new type of non-Hermitian phase transition in open systems far from thermal equilibrium, which can have place in the absence of an exceptional point, is demonstrated and pave the way to manipulate the heat energy transfer in the coupled out-of-equilibrium systems.

Exceptional Points as Lasing Prethresholds

The genesis of lasing, as an evolution of the laser hybrid eigenstates comprised of electromagnetic modes and atomic polarization, is considered. It is shown that the start of coherent generation at
