The Picoelectrodynamics Theory Network is working on decoding the interplay of electrodynamic fields deep inside matter at the atomic level. We are addressing the questions that will lead to the discovery of novel topological phases of matter, atomistic anomalous waves, vacuum, and thermal...

Topological optical N-insulators

Page
Topological Pico-Electrodynamics One of the key achievements of the last decade has been the realization that topology may be used to categorize and find new phases of matter (Nobel Prize in Physics in 2016). The inherent spin-orbit interaction in some materials, known as topological insulators...

Quantum Field Theory for Angular Momentum of Light

Page
Quantum sensing of photonic spin density using a single spin qubit Nitrogen vacancy (NV) centers in diamond have emerged as promising room temperature quantum sensors for probing condensed matter phenomena ranging from spin liquids, 2D magnetic materials, and magnons to hydrodynamic flow of current...

What is pico-electrodynamics? PED deals with the exploration of electrodynamic fields inside matter at the atomistic level. Some of the phenomena unique to the PED regime include new topological electrodynamic phases of matter, anomalous atomistic waves, and angular momentum of gauge fields coupled...

Purdue researchers control the quantum vacuum

News: December 13, 2021
Purdue researchers have made a breakthrough demonstration of controlling energy transfer mediated by vacuum fluctuations. They have proposed and demonstrated a non-reciprocal, diode-like Casimir device. Their results were published in Nature Nanotechnology. A striking prediction of quantum mechanics...
