In the paper, “Double semions in arbitrary dimension,” published in Communications in Mathematical Physics, Michael Freedman and Matthew Hastings present a new construction of topological phases of matter in higher dimensions, generalizing the double semion theory in two dimensions. This theory is distinct from the Dijkgraaf-Witten model and generalized toric code models. Read the published version. Read more
In this paper, which was just published in Physical Review B, a quantitative theory for the two-terminal conductance of a proximitized nanowire in the Coulomb blockade regime is developed. This theory allows one to understand and interpret the experimental data from the recent experiment by Charles Marcus’s group at Station Q Copenhagen that demonstrated Read more
Recent improvements in the control of quantum systems make it seem feasible to finally build a quantum computer within a decade. While it has been shown that such a quantum computer can in principle solve certain small electronic structure problems and idealized model Hamiltonians, the highly relevant problem of directly solving a complex correlated Read more
