DOI: 10.1073/pnas.2018248117
Abstract: What are the ground states of an interacting, low-density electron system? In the absence of disorder, it has long been expected that as the electron density is lowered, the exchange energy gained by aligning the… read more here.

DOI: 10.1103/physrevb.102.125423
Abstract: We observe strong spin-orbit interactions in a two-dimensional electron system formed on $\mathrm{SrTi}{\mathrm{O}}_{3}(001)$ films grown epitaxially on p-Si(001). High-resolution transmission electron microscopy and related analytical techniques reveal a sharp interface between Si and $\mathrm{SrTi}{\mathrm{O}}_{3}$. Strain… read more here.

DOI: 10.1103/physrevb.98.161303
Abstract: Hall viscosity is a nondissipative response function describing momentum transport in two-dimensional (2D) systems with broken time-reversal symmetry. In the classical regime, Hall viscosity contributes to the viscous flow of 2D electrons in the presence… read more here.

DOI: 10.1103/physrevlett.127.016801
Abstract: Electrons on the helium surface display sharp resonant absorption lines related to the transitions between the subbands of quantized motion transverse to the surface. A magnetic field parallel to the surface strongly affects the absorption… read more here.

DOI: 10.1140/epjd/e2020-10328-8
Abstract: The stability of two electron system under the influence of the exponential-cosine-screened-Coulomb (ECSC) potential has been studied as a function of continuously varying nuclear charge (Z) and screening constant (μ). Inter-electronic correlation has explicitly been… read more here.
