Nonlinear Quantum Spectroscopy System for Quantum Materials

Abstract

We propose developing a nonlinear spectroscopy system for measuring fractional symmetries, correlations, and many-body entanglement in quantum materials. Specifically, an optical parametric oscillator (OPO) and single photon detectors will be combined with a recently developed vacuum suitcase compatible magneto-optical cryostat, enabling broad band nonlinear Raman and photocurrent spectroscopies. This state of the art system will be the first combining low-energy impulsive Raman spectroscopy, full polarization control, and single photon correlation measurements to provide a new quantum light scattering system useful in many areas relevant to DOD (e.g. charge density wave, topological semimetals, and 2D heterostructures with novel excitations and extreme nonlinearities useful in nanoscale electronics, quantum computing and novel optical sensors). The new system will build on the PI’s recent accomplishments in developing Raman and Photocurrent spectroscopies to probe the complex responses of quantum materials. Expanding on this success the instrument will allow tuning the optical excitation across a broad range of relevant energies to probe the quantum geometry, correlations and ultimately entanglement. These cutting edge capabilities will be coupled to the PI’s existing magneto-optical system with vacuum suitcase to allow the study of bulk, thin films and 2D heterostructures at the forefront of condensed matter. As such the newly developed system will benefit multiple groups in Boston working at the forefront of quantum materials, especially those interested in probing the topological and correlated properties. Indeed the system will be highly automated, thus allowing the PI to build on his existing collaborations with groups in physics, chemistry, and engineering.
