Holographic fractional topological insulators in 2+1 and 1+1 dimensions
Andreas Karch, Joseph Maciejko, Tadashi Takayanagi
We give field theory descriptions of the time-reversal invariant quantum spin Hall insulator in 2+1 dimensions and the particle-hole symmetric insulator in 1+1 dimensions in terms…
Conductance and noise signatures of Majorana backscattering
Suk Bum Chung, Xiao-Liang Qi, Joseph Maciejko +1
We propose a conductance measurement to detect the backscattering of chiral Majorana edge states. Because normal and Andreev processes have equal probability for backscattering of…
Fractional topological insulators in three dimensions
Joseph Maciejko, Xiao-Liang Qi, Andreas Karch +1
Topological insulators can be generally defined by a topological field theory with an axion angle theta of 0 or pi. In this work, we introduce the concept of fractional topological…
Topological quantization in units of the fine structure constant
Joseph Maciejko, Xiao-Liang Qi, H. Dennis Drew +1
Fundamental topological phenomena in condensed matter physics are associated with a quantized electromagnetic response in units of fundamental constants. Recently, it has been pred…
