Imaging Electron-Hole Asymmetry in the Quantum Melting of Generalized Wigner Crystals
Emma Berger, Michael Arumainayagam, Zhihuan Dong +12
Two-dimensional moiré materials provide a versatile platform to explore phase transitions in strongly correlated systems. Using scanning tunneling microscopy (STM) we have imaged t…
Visualizing the Impact of Quenched Disorder on 2D Electron Wigner Solids
Zhehao Ge, Conor Smith, Zehao He +17
Electron Wigner solids (WSs)1-12 provide an ideal system for understanding the competing effects of electron-electron and electron-disorder interactions, a central unsolved problem…
Atomic dynamics and local structural disorder during ultrafast melting of polycrystalline Pd
Adam Olczak, Ryszard Sobierajski, Przemyslaw Dziegielewski +8
The primary distinction between solid and liquid phases is mechanical rigidity, with liquids having a disordered atomic structure that allows flow. While melting is a common phase…
