自旋选择绝缘体

Spin-selective insulators

J. Silva-Valencia

摘要:

自旋选择绝缘体出现在由两个内部自由度的费米子和另一个载流子组成的系统中,该载流子可以是费米子或玻色子。这些绝缘体的特征是一种费米子的无隙态和另一种费米子的绝缘体态,后者满足一个包含另一种载流子的双态关系。我们回顾了这些独特的绝缘体出现的不同情况,专注于玻色费米混合物,最近和有前途的情况下观察这些绝缘体在冷原子设置。

英文摘要:

Spin-selective insulators emerge in systems composed of fermions with two internal degrees of freedom and another carrier, which could be fermionic or bosonic. These insulators are characterized by a gapless state for one kind of fermion and an insulator state for the other, with the latter satisfying a commensurability relation that involves the other carrier. We review the different scenarios where these unique insulators arise, focusing on Bose-Fermi mixtures, the most recent and promising scenario for observing these insulators in cold atom setups.
