Kelvin-Helmholtz instability is the result of parity-time symmetry breaking

, 2018
Parity-Time (PT)-symmetry is being actively investigated as a fundamental property of observables in quantum physics. We show that the governing equations of the classical two-fluid interaction and the incompressible fluid system are PT-symmetric, and ...

Exact Kerr-like solution and its shadow in a gravity model with spontaneous Lorentz symmetry breaking [PDF]

The European Physical Journal C, 2019
We obtain an exact Kerr-like black hole solution by solving the corresponding gravitational field equations in Einstein-bumblebee gravity model where Lorentz symmetry is spontaneously broken once a vector field acquires a vacuum expectation value ...

Entanglement and Spontaneous Symmetry Breaking in Quantum Spin Models

, 2003
It is shown that spontaneous symmetry breaking does not modify the ground-state entanglement of two spins, as defined by the concurrence, in the XXZ- and the transverse field Ising-chain.

Spontaneous breaking of spatial and spin symmetry in spinor condensates [PDF]

, 2010
Parametric amplification of quantum fluctuations constitutes a fundamental mechanism for spontaneous symmetry breaking. In our experiments, a spinor condensate acts as a parametric amplifier of spin modes, resulting in a twofold spontaneous breaking of ...

Spontaneous symmetry breaking of coupled Fabry–Pérot nanocavities

Communications Physics
Ring cavities are quickly emerging as preferential platforms to investigate spontaneous symmetry breaking. However, research on handedness polarisation splitting within Kerr-coupled cavities is yet at a preliminary stage.

Spontaneous symmetry breaking and response functions [PDF]

, 2004
We study the quantum phase transition occurring in an infinite homogeneous system of spin 1/2 fermions in a non-relativistic context. As an example we consider neutrons interacting through a simple spin-spin Heisenberg force.

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

Advanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Diagnosing strong-to-weak symmetry breaking via Wightman correlators

Communications Physics
Symmetry plays a fundamental role in quantum many-body physics, and a central concept is spontaneous symmetry breaking. Recent developments highlight new symmetry-breaking patterns known as strong-to-weak spontaneous symmetry breaking, characterized by ...

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.
