Abstract

We are witnessing and participating the grand discovery of various topological states of matter.
In this talk, I will introduce time-reversal-invariant topological superconductivity and its two
experimental realizations in one dimension. Each boundary hosts one Majorana Kramers pair,
producing tabletop supersymmetry, quantized tunneling conductance, and fractional Josephson
effects beyond Kitaev
s classification. I will then highlight the tantalizing roles played by the
many-body interactions. One prime example is the emergence of quadruple periodicity and
fractionalized parafermions in a Josephson junction. Another paradigmatic setup is a weakly
probed floating topological superconductor, in which a two-channel Kondo ground state becomes
topologically stabilized.
