The emergence of exceptional points (EPs) in the parameter space of a (2D) eigenvalue problem is studied in a general sense in mathematical physics. In coupled systems, it gives rise to unique physical phenomena upon which novel approaches for the development of seminal types of highly sensitive sensors shall leverage their fascinating properties. Here, we demonstrate at room temperature the emergence of EPs in coupled spintronic nanoscale oscillators, coming along with the observation of…

Exceptional points in classical spin dynamics
TLDR
It is shown that encircling individual EPs in a parameter space results in non-reciprocal spin dynamics and the range of optimal protocol parameters for high-efficiency asymmetric spin filter based on this effect is found.
Exceptional points in dissipatively coupled spin dynamics
We theoretically investigate dynamics of classical spins exchange-coupled through an isotropic medium. The coupling is treated at the adiabatic level of the medium's response, which mediates a
Dynamically encircling an exceptional point for asymmetric mode switching
TLDR
It is demonstrated that a dynamical encircling of an exceptional point is analogous to the scattering through a two-mode waveguide with suitably designed boundaries and losses, and mode transitions are induced that transform this device into a robust and asymmetric switch between different waveguide modes.
Mutual synchronization of spin torque nano-oscillators through a long-range and tunable electrical coupling scheme
TLDR
This work demonstrates the successful mutual synchronization of two spin-torque oscillators with a large separation distance through their long range self-emitted microwave currents, leading to a strong improvement of both the emitted power and the linewidth.
Mutual phase-locking of microwave spin torque nano-oscillators
TLDR
It is shown that two STNOs in close proximity mutually phase-lock—that is, they synchronize, which is a general tendency of interacting nonlinear oscillator systems.
Enhanced sensitivity at higher-order exceptional points
TLDR
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.
Vowel recognition with four coupled spin-torque nano-oscillators
TLDR
The results demonstrate that non-trivial pattern classification tasks can be achieved with small hardware neural networks by endowing them with nonlinear dynamical features such as oscillations and synchronization, and that the high experimental recognition rates stem from the ability of these oscillators to synchronize.
Scaling up electrically synchronized spin torque oscillator networks
TLDR
This study demonstrates that spin-torque oscillators are suitable for applications based on synchronized networks of oscillators, and demonstrates that the stability of synchronization in time exceeds 1.6 milliseconds corresponding to 105 periods of oscillation.
Level attraction and exceptional points in a resonant spin-orbit torque system
Level attraction can appear in driven systems where instead of repulsion two modes coalesce in a region separated by two exceptional points. This behavior was proposed for optomechanical and
Topological energy transfer in an optomechanical system with exceptional points
TLDR
This work demonstrates the transfer of energy between two vibrational modes of a cryogenic optomechanical device using topological operations and shows that this transfer arises from the presence of an exceptional point in the spectrum of the device, which is non-reciprocal.
