N. Peter Armitage

Appointment

Fellow

Quantum Materials

About

N. Peter Armitage is a physicist whose research centers on understanding material systems which exhibit coherent quantum effects at low temperatures, like superconductors and quantum magnetism.

His principal scientific interest is understanding how it is that large ensembles of strongly interacting, but fundamentally simple particles like electrons in solids, act collectively to exhibit complex emergent quantum phenomena.  He is exploiting (and developing) recent technical breakthroughs using very low frequency microwave and THz range radiation to probe these systems at their natural frequency scales. The material systems of interest require new measurement techniques since their relevant frequencies typically fall between the range of usual optical and electronic methods.  He has recently been interested in the quantized response functions that characterize topological states of matter, as well as developing new techniques that allow the measurement of previously hidden correlations in states of matter like spin liquids.
