Seminar Link: Picoelectrodynamics Theory Network - YouTube Abstract We discuss how the many-body excitation spectrum of topological insulators is affected by the presence of long-range Coulomb interactions. In the one-dimensional Su-Schrieffer-Heeger model and its mirror-symmetric variant, strongly...

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 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 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...
