Axions are hypothetical particles that were proposed to solve the strong charge–parity
problem in high-energy physics. Although they have long been known in quantum field …

Interactions induced by electromagnetic fluctuations, such as van der Waals and Casimir
forces, are of universal nature present at any length scale between any types of systems …

We propose to realize mechanical parity-time (PT) symmetry in two coupled optomechanical
systems. To provide gain to one mechanical resonator and the same amount of dam** to …

We give an overview of the work done during the past ten years on the Casimir interaction in
electronic topological materials, our focus being solids, which possess surface or bulk …

We focus on the transmission and reflection coefficients of light in systems involving
topological insulators (TIs). Due to the electromagnetic coupling in TIs, new mixing …

Dynamic tuning of optical cavities is highly desired in many photonic systems. Here, we
show that Fabry-Pérot (FP) cavities can be actively controlled by the Casimir force. The …

Here, we present a critical review of recent developments in Casimir physics motivated by
discoveries of novel materials. Specifically, topologically nontrivial properties of the …

For nonreciprocal objects in vacuum, the Casimir interaction can become repulsive. Here,
we present a comprehensive study for idealized nonreciprocal materials known as perfect …

In this paper we critically reconsider the Casimir repulsion between surfaces that carry the
Chern-Simons interaction (corresponding to the Hall-type conductivity). We present a …

Quantum and thermal fluctuations are fundamental to a plethora of phenomena within
quantum optics, including the Casimir effect that acts between closely separated surfaces …
