Probing carrier interactions using electron hydrodynamics
Georgios Varnavides, Adam S. Jermyn, Polina Anikeeva +1
Electron hydrodynamics arises when momentum-relaxing scattering processes are slow compared to momentum-conserving ones. While the microscopic details necessary to satisfy this con…
Generalized Design Principles for Hydrodynamic Electron Transport in Anisotropic Metals
Yaxian Wang, Georgios Varnavides, Polina Anikeeva +3
Interactions of charge carriers with lattice vibrations, or phonons, play a critical role in unconventional electronic transport of metals and semimetals. Recent observations of ph…
Finite-size effects of electron transport in PdCoO
Georgios Varnavides, Yaxian Wang, Philip J. W. Moll +2
A wide range of unconventional transport phenomena have recently been observed in single-crystal delafossite metals. Here, we present a theoretical framework to elucidate electron…
Capturing 3D atomic defects and phonon localization at the 2D heterostructure interface
Xuezeng Tian, Xingxu Yan, Georgios Varnavides +9
The 3D local atomic structures and crystal defects at the interfaces of heterostructures control their electronic, magnetic, optical, catalytic and topological quantum properties,…
Imaging phonon-mediated hydrodynamic flow in WTe2
Uri Vool, Assaf Hamo, Georgios Varnavides +12
In the presence of interactions, electrons in condensed-matter systems can behave hydrodynamically, exhibiting phenomena associated with classical fluids, such as vortices and Pois…
Direct Imaging and Electronic Structure Modulation of Moiré Superlattices at the 2D/3D Interface
Kate Reidy, Georgios Varnavides, Joachim Dahl Thomsen +7
The atomic structure at the interface between two-dimensional (2D) and three-dimensional (3D) materials influences properties such as contact resistance, photo-response, and high-f…
Generalized Electron Hydrodynamics, Vorticity Coupling, and Hall Viscosity in Crystals
Georgios Varnavides, Adam S. Jermyn, Polina Anikeeva +2
Theoretical and experimental studies have revealed that electrons in condensed matter can behave hydrodynamically, exhibiting fluid phenomena such as Stokes flow and vortices. Unli…
Non-Equilibrium Phonon Transport Across Nanoscale Interfaces
Georgios Varnavides, Adam S. Jermyn, Polina Anikeeva +1
Despite the ubiquity of applications of heat transport across nanoscale interfaces, including integrated circuits, thermoelectrics, and nanotheranostics, an accurate description of…
Magnetically Multiplexed Heating of Single Domain Nanoparticles
Michael G. Christiansen, Ritchie Chen, Polina Anikeeva
Selective hysteretic heating of multiple collocated sets of single domain magnetic nanoparticles (SDMNPs) by alternating magnetic fields (AMFs) may offer a useful tool for biomedic…
