We show the existence of topological phases of Bloch insulators with time-reversal symmetry
in three dimensions. These phases are characterized by topological Z 2 invariants whose …

Recent numerical simulations of flat-band models with interactions which show clear
evidence of fractionalized topological phases in the absence of a net magnetic field have …

We study the phases of Bloch insulators with time-reversal symmetry on the basis of the
homotopy of the ground-state wave functions in momentum space and find that there are two …

Dynamical phases with novel topological properties are known to arise in driven systems of
free fermions. In this paper, we obtain a ‘periodic table’ to describe the phases of such time-…

Single-molecule fluorescence resonance energy transfer (smFRET) is one of the most
general and adaptable single-molecule techniques. Despite the explosive growth in the …

Single-stranded DNA generated in the cell during DNA metabolism is stabilized and
protected by binding of ssDNA-binding (SSB) proteins. Escherichia coli SSB, a representative …

Many phenomena in physics, chemistry, and biology can be modelled by spatial random
processes. One such process is continuum percolation, which is used when the phenomenon …

Imaging single fluorescent proteins in living mammalian cells is challenged by out-of-focus
fluorescence excitation. To reduce out-of-focus fluorescence we developed reflected light-…

We present a pedagogical review of the physics of fractional Chern insulators with a
particular focus on the connection to the fractional quantum Hall effect. While the latter …

The excitation spectrum of a two-dimensional p x+ ipy fermionic superfluid, such as a thin
film of 3 He− A, includes a gapless Majorana-Weyl fermion which is confined to the boundary …
