- Title: Size Matters: Lorentz Boosted Casimir Effect
- Abstract summary: We study the Lorentz boost of a Casimir cavity, on which little attention is paid to its momentum in historical works.
We find that the vacuum energy and momentum carried by the cavity transform differently from those of point particles due to the cavity's extension feature.

- Abstract: Many evidences appear in the past decades and show that the negativity of Casimir energy is responsible for exotic mechanical and gravitational effects. We study in this work the Lorentz boost of a Casimir cavity, on which little attention is paid to its momentum in historical works. We find that the vacuum energy and momentum carried by the cavity transform differently from those of point particles due to the cavity's extension feature. However, the mass-shell condition of the two are identical as long as the cavity is finite along the moving direction only.

We investigate what types of Casimir effects can occur from quark fields in dense and thin quark matter.
In particular, in the dual chiral density wave, we find that the Casimir energy oscillates as a function of the thickness of matter.
This oscillating Casimir effect is regarded as an analog of that in Weyl semimetals and is attributed to the Weyl points in the momentum space of quark fields.

The Casimir effect is a macroscopic evidence of the quantum nature of the vacuum.

Thin Films [62.997667081978825]
Casimir forces, related to London-van der Waals forces, arise if the spectrum of electromagnetic fluctuations is restricted by boundaries.
We experimentally investigate the influence of self-assembled molecular bio and organic thin films on the Casimir force between a plate and a sphere.
We find that molecular thin films, despite being a mere few nanometers thick, reduce the Casimir force by up to 14%.

We develop a magnonic analog of the Casimir effect into non-Hermitian systems.
We show that this non-Hermitian Casimir effect of magnons is enhanced as the Gilbert damping constant increases.
Our result suggests that energy dissipation serves as a key ingredient of Casimir engineering.

We investigate the Casimir effect for various dispersion relations on the lattice.
We find that Casimir effects for dispersions proportional to an even power of momentum are absent in a long distance but a remnant of the Casimir effect survives in a short distance.
Such a remnant Casimir effect will be experimentally observed in materials with quantum fields on the lattice, such as thin films, narrow nanoribbons, and short nanowires.
