Space charge and screening of a supercritical impurity cluster in monolayer graphene
Eugene B. Kolomeisky, Joseph P. Straley
Coulomb impurity of charge is known to destabilize the ground state of undoped graphene with respect to creation of screening space charge if exceeds a critical value of $…
Vortex wake patterns in superfluid
Eugene B. Kolomeisky
Excitations in the form of quantized vortex rings are known to exist in superfluid at energies and momenta exceeding those of the Landau phonon-roton spectrum. They form a…
Splashes in isotropic media
Eugene B. Kolomeisky
The response of a medium to a sudden localized perturbation (a "splash") will be explained for isotropic media within the framework of linear response theory. In this theory splash…
Negative group velocity and Kelvin-like wake pattern
Eugene B. Kolomeisky, Jonathan Colen, Joseph P. Straley
Wake patterns due to a uniformly traveling source are a result of the resonant emission of the medium's collective excitations. When there exists a frequency range where such excit…
Kelvin-Mach wake in a two-dimensional Fermi sea
Eugene B. Kolomeisky, Joseph P. Straley
The dispersion law for plasma oscillations in a two-dimensional electron gas in the hydrodynamic approximation interpolates between and dependences…
Screening and plasma oscillations in an electron gas in the hydrodynamic approximation
Eugene B. Kolomeisky, Joseph P. Straley
A hydrodynamic theory of screening in a generic electron gas of arbitrary dimensionality is given that encompasses all previously studied cases and clarifies the predictions of the…
