It is demonstrated that topological insulator lasers are theoretically possible and experimentally feasible and shown that the underlying topological properties lead to highly efficient lasers, robust to defects and disorder, with single-mode lasing even at conditions high above the laser threshold.

This work proposes and discusses two computational algorithms that search for optimal potentials for self- assembly of a given target configuration and demonstrates that the algorithms do indeed cause self-assembly of the target lattice.

The first experimental observation of a topological transition in a non-Hermitian system is presented, and standard methods for examining topological properties, which involve probing edge (or surface) states, are ignored.
Optimized interactions for targeted self-assembly: application to a honeycomb lattice.

An inverse statistical-mechanical methodology to find optimized interaction potentials that lead spontaneously to a target many-particle configuration, extending the traditional idea of self-assembly to incorporate both amorphous and crystalline structures as well as quasicrystals.
Self-assembly of the simple cubic lattice with an isotropic potential.

An isotropic pair potential V(r) is presented for a three-dimensional many-particle system whose classical ground state is the low-coordinated simple cubic lattice and it is shown that standard approximate integral-equation theories of the liquid state cannot be used in the reverse mode to predict the correct simple cubic potential.
