Quantum‐Mechanical Wave Functions in Singular Potentials: Linear and Nonlinear States

open access: yesAdvanced Physics Research, EarlyView.
The attractive singular potential −1/r2$-1/r^2$ gives rise to the quantum collapse in the 3D linear Schroedinger equation. The article summarizes theoretical results demonstrating suppression of the collapse and creation of the missing ground state (GS) in a gas of bosonic particles, carrying an electric dipole moment, which are pulled to the central ...

Compactons and topological solitons of the Drinfel'd–Sokolov system

open access: yesNonlinear Analysis, 2014
This paper presents the Drinfel’d–Sokolov system (shortly D(m, n)) in a detailed fashion. The Jacobi’s elliptic function method is employed to extract the cnoidal and snoidal wave solutions. The compacton and solitary pattern solutions are also retrieved.

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

open access: yesAdvanced Physics Research, EarlyView.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

Interface Engineering in Piezoelectric‐on‐Insulator Platforms: Coupling of Electrons, Photons, and Phonons for Multifunctional Integration

open access: yesElectron, EarlyView.
The underlying interface physics and engineering strategies across key POI material systems, including LiNbO3/Si, LiNbO3/SiC, LiNbO3/diamond, and AlN/diamond, were reviewed. The key engineering strategies such as atomic‐scale bonding optimization, nanostructuring, ultrathin phonon‐bridge interlayers, and ferroelectric domain wall engineering for ...

Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Multi-soliton dynamics of anti-self-dual gauge fields

open access: yesJournal of High Energy Physics, 2022
We study dynamics of multi-soliton solutions of anti-self-dual Yang-Mills equations for G = GL(2, ℂ) in four-dimensional spaces. The one-soliton solution can be interpreted as a codimension-one soliton in four-dimensional spaces because the principal ...

Visible Octave Frequency Combs in Silicon Nitride Nanophotonic Waveguides Driven by Ti:Sapphire Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

open access: yesLaser &Photonics Reviews, EarlyView.
This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.
