Gravitational Instabilities in Circumstellar Disks [PDF]
, 2016 [Abridged] Star and planet formation are the complex outcomes of gravitational collapse and angular momentum transport mediated by protostellar and protoplanetary disks. In this review we focus on the role of gravitational instability in this process. We

Suppressing spatiotemporal lasing instabilities with wave-chaotic microcavities [PDF]
Science, 2018 Taming laser instabilities Broad-area and high-power lasers often suffer from instabilities owing to the chaotic interference of multiple modes within the cavity.

A Novel Mechanism of Pair Creation in Pulsar Magnetospheres
Universe, 2021 In this paper we study the possibility of efficient pair production in a pulsar’s magnetosphere. It has been shown that by means of relativistic centrifugal force the electrostatic field exponentially amplifies.

Electromagnetic radiation related to dislocation dynamics in a seismic preparation zone
Annals of Geophysics, 2002 Electromagnetic emission is observed frequently before earthquakes as high noise level in VLF and ULF bands. We present theoretical considerations on electromagnetic radiation caused by dislocation dynamics in the preseismic micro-sources (micro ...

Magnetocentrifugal Mechanism of Pair Creation in AGN
Universe, 2023 In this study, we examine the efficiency of pair creation by means of the centrifugal mechanism. The strong magnetic field and the effects of rotation, which always take place in Kerr-type black holes, guarantee the frozen-in condition, leading to the ...

Fermi-liquid instabilities at magnetic quantum phase transitions [PDF]
, 2006 This review discusses instabilities of the Fermi-liquid state of conduction electrons in metals with particular emphasis on magnetic quantum critical points. Both the existing theoretical concepts and experimental data on selected materials are presented;

Emission Modes in Electrospray Thrusters Operating with High Conductivity Ionic Liquids
Aerospace, 2020 Electrospray thruster life and mission performance are strongly influenced by grid impingement, the extent of which can be correlated with emission modes that occur at steady-state extraction voltages, and thruster command transients.
