Visualization and Control of Quasi‐Monoenergetic Proton Shock Waves in a Single Nanoplasma
Nanophotonics, Volume 15, Issue 13, 13 July 2026.Femtosecond laser pulses irradiate isolated gold nanoparticles to yield tunable quasi‐monoenergetic proton shells. Proton energy correlates linearly with laser intensity, providing a compact scheme for easily modulated laser‐driven ion sources. ABSTRACT This work demonstrates direct visualization and deterministic control of quasi‐monoenergetic proton ...

, 2020 We consider an integro-differential 2-component multidimensional Gross-Pitaevskii equation with a Manakov-type cubic nonlocal nonlinearity. In the framework of the WKB-Maslov semiclassical formalism, we obtain a semiclassically reduced 2-component ...

Polaron Dynamics in a Quasi-Two-Dimensional Bose–Einstein Condensate
Universe, 2023 The concept of polaron quasiparticles was first introduced in the pioneering papers by Landau and Feynman in the 1930s and 1940s. It describes the phenomenon of an external particle producing a bound state in an embedded medium.

Standing waves of nonlinear Schrödinger systems with all attractive forces
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract Since the pioneering work of Lin and Wei on nonlinear Schrödinger systems of n$n$ components with interaction forces aij$a_{ij}$ between the i$i$‐th and j$j$‐th components for 1⩽i,j⩽n$1\leqslant i,j\leqslant n$, there have been numerous further developments in many directions. However, even in the simplest case where all interaction forces are

The Gross–Pitaevskii equation: Bäcklund transformations and admitted solutions
, 2018 Bäcklund transformations are applied to study the Gross-Pitaevskii equation. Supported by previous results, a class of Bäcklund transformations admitted by this equation are constructed.

Conserved energies for the one dimensional Gross-Pitaevskii equation
, 2020 We prove the global-in-time well-posedness of the one dimensional Gross-Pitaevskii equation in the energy space, which is a complete metric space equipped with a newly introduced metric and with the energy norm describing the H$^{8}$ regularities of the ...

Multiple front and pulse solutions in spatially periodic systems
Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.Abstract In this paper, we develop a comprehensive mathematical toolbox for the construction and spectral stability analysis of stationary multiple front and pulse solutions to general semilinear evolution problems on the real line with spatially periodic coefficients.

Density matrix form of Gross-Pitaevskii equation
, 2014 We consider the generalized pure state density matrix which depends on different time moments. The evolution equation for this density matrix is obtained in case where the density matrix corresponds to the solutions of Gross-Pitaevskii ...

The Casimir-like effect in a one-dimensional Bose gas
New Journal of Physics, 2019 The electromagnetic Casimir effect manifests as the interaction between uncharged conducting objects that are placed in a vacuum. More generally, the Casimir-like effect denotes an induced interaction between external bodies in a fluctuating medium.
