Inhomogeneous Evolution of a Dense Ensemble of Optically Pumped Excitons to a Charge Transfer State
Natasha Kirova, Serguei Brazovskii
Phase transformations induced by short optical pulses are mainstream in studies on the dynamics of cooperative electronic states. We present a semi-phenomenological modeling of spa…
Multi-fluid hydrodynamics in charge density waves with collective, electronic, and solitonic densities and currents
Serguei Brazovskii, Natasha Kirova
We present a general scheme to approach the space - time evolution of deformations, currents, and the electric field in charge density waves related to appearance of intrinsic topo…
Phase slips, dislocations, half-integer vortices, two-fluid hydrodynamics and the chiral anomaly in charge and spin density waves
Serguei Brazovskii, Natasha Kirova
This brief review recalls some chapters in theory of sliding incommensurate density waves which may have appeared after inspirations from studies of I.E Dzyaloshinskii and collabor…
From chiral anomaly to two-fluid hydrodynamics for electronic vortices
Serguei Brazovskii, Natasha Kirova
Many recent experiments addressed manifestations of electronic crystals, particularly the charge density waves, in nano-junctions, under electric field effect, at high magnetic fie…
The excitonic insulator route through a dynamical phase transition induced by an optical pulse
Serguei Brazovskii, Natasha Kirova
We consider a dynamical phase transition induced by a short optical pulse in a system prone to thermodynamical instability. We address the case of pumping to excitons whose density…
Dynamical patterns of phase transformations from self-trapping of quantum excitons
Tianyou Yi, Natasha Kirova, Serguei Brazovskii
Phase transitions induced by short optical pulses is a new mainstream in studies of cooperative electronic states. Its special realization in systems with neutral-ionic transformat…
Modeling of dislocations in a CDW junction: interference of the CDW and the normal carriers
Alvaro Rojo Bravo, Tianyou Yi, Natasha Kirova +1
We derive and study equations for dissipative transient processes in a constraint incommensurate charge density wave (CDW) with remnant pockets or a thermal population of normal ca…
Multi-vortex dynamics in junctions of charge density waves
T. Yi, A. Rojo-Bravo, N. Kirova +1
Ground state reconstruction by creation of topological defects in junctions of CDWs is a convenient playground for modern efforts of field-effect transformations in strongly correl…
Observation of correlations up to the micrometer scale in sliding charge-density waves
D. Le Bolloc'h, V. L. R. Jacques, N. Kirova +4
High-resolution coherent x-ray diffraction experiment has been performed on the charge density wave (CDW) system KMoO. The satellite reflection associated with t…
Topological coupling of dislocations and magnetization vorticity in Spin Density Waves
S. Brazovski, N. Kirova
The rich order parameter of Spin Density Waves allows for an unusual object of a complex topological nature: a half-integer dislocation combined with a semi-vortex of the staggered…
