Casimir effect in dual chiral density waves

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

In this talk, we discuss the discovery of a new Casimir effect that emerges from the quark field in dense, thin quark matter when the magnetic field is zero or non-zero. Surprisingly, in the dual chiral density wave (DCDW) phase, a candidate ground state of dense quark matter, the Casimir energy oscillates as a function of thickness. This finding highlights a novel oscillating Casimir phenomenon driven by QCD dynamics in extreme conditions.
