Reflectance of two materials

Extreme ultraviolet optical constants

Ongoing
In the vacuum ultraviolet and extreme ultraviolet (EUV), the indices of refraction of all materials become complex: N = n + ik, or N = 1- d + ik. Here, n is the

Micro- and nano-optomechanical systems

Ongoing
Light can interact with mechanical systems in interesting and useful ways, not only probing the mechanical motion with spectacular sensitivity, but also driving

Self-dual quasiperiodic percolation

Author(s)
Grace Sommers, Michael Gullans, David Huse
How does the percolation transition behave in the absence of quenched randomness? To address this question, we study a nonrandom self-dual quasiperiodic model
