We use a collection of experimental tools to characterize and manipulate the collective states of Avogadro number of electrons, particularly in van der Waals heterostructures.
The ground and excited states of these emergent phenomena, such as superconductivity, magnetism, and topology, will underpin future energy-efficient devices.
Quantum sensors based on atomic defects in diamond leverage the fundamental principles of quantum mechanics to directly reveal unprecedented nanoscale quantities from quantum states.
The van der Waals (vdW) heterostructures, composed of 2D materials, transcend the constraints of chemistry and lattice matching, facilitating the deliberate design of programmable quantum states.
The emergent states in vdW heterostructures can be characterized against tuning knobs such as temperature, magnetic field, carrier density, perpendicular electric field, and more.
