Fermionic Response in Finite-Density ABJM Theory with Broken Symmetry

Oliver DeWolfe, Steven S. Gubser, Oscar Henriksson, Christopher Rosen

摘要:

我们计算了四维规范超引力场畴壁背景中的费米子响应。Bobev等人发现的背景,的全息对偶ABJM理论的零温度状态在有限密度的电荷和类似的零温度极限的全息超导体,但也有一个破缺源。凝聚标量混合了带电场和中性场,对偶于狄拉克方程中的复合费米子算符。发现了稳定准粒子的带隙和无带隙带。

英文摘要:

We calculate fermionic response in domain wall backgrounds of four-dimensional gauged supergravity interpolating between distinct stable AdS vacua. The backgrounds, found by Bobev et al., are holographically dual to zero-temperature states of ABJM theory at finite density for monopole charge and are similar to zero-temperature limits of holographic superconductors, but with a symmetry-breaking source as well. The condensed scalar mixes charged and neutral fields dual to composite fermionic operators in the Dirac equations. Both gapped and gapless bands of stable quasiparticles are found.
