Eddwi Hesky Hasdeo
I am a theoretical condensed matter physicist investigating the fundamental aspects of electron, photon, and phonon dynamics in solids. My primary research explores the fascinating consequences of quantum geometry, Berry curvature, electron hydrodynamics (viscous Navier-Stokes electron flows), topological photonics for quantum computing, and thermoelectric transport in low-dimensional materials.
Research Highlights
My research bridges quantum materials, photonics, and hydrodynamic transport to understand non-classical driving forces in solids and discover platforms for future quantum technologies:
🌊 Hydrodynamic Electron Transport
Developing Navier-Stokes equations for electrons in clean 2D materials. Discovered Coulomb drag viscosity, negative drag conductivity in viscous channels (Phys. Rev. B 2023), and quantum geometric Berry curvature corrections to electronic flow (Phys. Rev. B 2021).
Read topic overview →⚛ Quantum Geometry & Optoelectronics
Investigating how the internal structure of the electronic wave function (quantum metric and Berry curvature) dictates cyclotron motion without magnetic fields (New J. Phys. 2019) and optical rotations in topological flat bands (New J. Phys. 2022).
Read topic overview →💻 Topological Optics & Qubit Entanglement
Demonstrating topological surface waves (unidirectional Surface Plasmon Polaritons) in Weyl semimetals. Utilizing unidirectional SPPs to mediate long-lived entanglement between quantum bits (qubits) for quantum architectures (Phys. Rev. B 2022).
Read topic overview →⚡ Thermoelectric Transport in Nanostructures
Formulating the universal quantum confinement rule ($L / \Lambda < 1$) for enhanced thermoelectric power factors in nanostructures (Phys. Rev. Lett. 2016) and optimizing bandgaps in Dirac materials (J. Appl. Phys. 2019).
