论文摘要
复杂阶参数波动的受控动力探针测量可能揭示其大规模的集体激发。在这里，我们设计动态淬灭协议，以独立激发各向同性Balian中的所有十个Midgap Higgs玻色子 - 跨度$ p $ - wave superfluid或superpocductor的Werthamer状态。该分析基于SO（5）伪词的运动的显微镜方程，这是将通常的Bloch方程扩展到五个维空间。这些协议的关键是实现破坏动能的旋转对称性并利用角动量$ j = 2 $的不可约表示的淬火。对于扰动淬灭，我们在这些HIGGS模式的时间内发现（未折扣）周期性振荡。考虑了实现我们对超流体或超导体的建议的实验。
Controlled dynamical probe measurement of complex order parameter fluctuations may reveal its massive collective excitations. Here, we design dynamical quench protocols to excite independently all ten midgap Higgs bosons in the isotropic Balian--Werthamer state of a spinfull $p$-wave superfluid or superconductor. The analysis is based on microscopic equations of motion of an SO(5) pseudospin, an extension of the usual Bloch equation to a five dimensional space. Key to these protocols is the realization of quenches that break the rotational symmetry of the kinetic energy and exploit the irreducible representation of the angular momentum $J=2$. For perturbative quenches, we find (non-decaying) periodic oscillations in time of these Higgs modes. Experiments to realize our proposal for either superfluids or superconductors are considered.
