Casimir effect in the dual chiral density wave

Fujii, Daisuke; Suzuki, Kei   ; Nakayama, Katsumasa*

Recently, new types of Casimir effects realized in condensed matter systems have been discovered. For example, the photonic Casimir effect in Weyl semimetals was found to exhibit remarkable behavior. This new type of Casimir effect may also be realized in dense quark matter. In this presentation, we discuss typical features of the Casimir effect in finite density QCD using the Nambu-Jona-Lasinio model. In particular, an remarkable behavior of the Casimir effect in the dual chiral density wave phase is revealed.
