• Authors: Daisuke Fujii, Katsumasa Nakayama, Kei Suzuki,
• Abstract summary: 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.

• Abstract: The Casimir effect is known to be induced from photon fields confined by a small volume, and also its fermionic counterpart has been predicted in a wide range of quantum systems. Here, 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, which is a possible ground state of dense quark matter, 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. In addition, we show that an oscillation is also induced from the quark Fermi sea, and the total Casimir energy is composed of multiple oscillations.

  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 observe that the entanglement phase transitions occurring in the stationary state have the same nature as that occurring in the vacuum of the non-hermitian Hamiltonian.

• Dirac/Weyl-node-induced oscillating Casimir effect [0.0]
  The Casimir effect is a quantum phenomenon induced by the zero-point energy of relativistic fields confined in a finite-size system. We show the typical properties of the Casimir effect for relativistic electron fields in Dirac/Weyl semimetals. We find an oscillation of the Casimir energy as a function of the thickness of the thin film, which stems from the existence of Dirac/Weyl nodes in momentum space.

• Remnants of the nonrelativistic Casimir effect on the lattice [0.0]
  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.

  We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
