标题： Dual chiral density wave induced oscillating Casimir effect

摘要： 卡西米尔效应已被知为由限制在小体积内的光子场诱导产生，并且其费米子对应物也被预测存在于广泛的量子系统中。 在这里，我们研究了在密集而薄的夸克物质中的夸克场可以产生哪些类型的卡西米尔效应。 特别是，在可能作为密集夸克物质基态的对偶手征密度波中，我们发现卡西米尔能量会随着物质厚度的变化而振荡。 这种振荡的卡西米尔效应被视为类似于外尔半金属中的效应，并归因于夸克场动量空间中的外尔点。 此外，我们还表明，夸克费米海也会诱导出振荡现象，总卡西米尔能量由多个振荡组成。 显示英文摘要

摘要： 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.
