We predict that in thin … WebA topological insulator is an insulator whose Hamiltonian cannot be adiabatically connected to the atomic limit. Adiabatic means that, when tuning some external parameter (e.g. pressure, temperature) to change the Hamiltonian, the process is slow enough that the material stays in its ground state throughout. Qualitative picture.

WebEpsilon-near-zero and epsilon near-pole materials enable reflective systems supporting a class of symmetry-protected and accidental embedded eigenstates (EEs) characterized by a diverging phase resonance.
