4 Jan 2023 | Abstract: | The Wigner crystal, an ordered array of electrons, is one of the very first
proposed many-body phases stabilized by the electron-electron interaction. This
electron solid phase has been reported in ultra-clean two-dimensional electron
systems at extremely low temperatures, where the Coulomb interaction dominants
over the kinetic energy, disorder potential and thermal fluctuation. We closely
examine this quantum phase with capacitance measurements where the device
length-scale is comparable with the crystal’s correlation length. The
extraordinarily high performance of our technique makes it possible to
quantitatively study the dynamic response of the Wigner crystal within the
single crystal regime. Our result will greatly boost the study of this
inscrutable electron solid. | Source: | arXiv, 2301.01475 | Services: | Forum | Review | PDF | Favorites |
