Solitons of the constrained Schrödinger equations

Journal of Physics Communications
We consider the linear vector Schrödinger equation subjected to quadratic constraints. We demonstrate that the resulting nonlinear system is closely related to the Ablowitz-Ladik hierarchy and use this fact to derive the N -soliton solutions for the ...

Solutions to a nonlinear Schr\"odinger equation with periodic potential and zero on the boundary of the spectrum [PDF]

, 2014
We study the following nonlinear Schr\"odinger equation $$-\Delta u + V(x) u = g(x,u),$$ where V and g are periodic in x. We assume that 0 is a right boundary point of the essential spectrum of $-\Delta+V$.

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser

Advanced Science, Volume 13, Issue 28, 18 May 2026.
An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling

A modified Jacobi elliptic functions method for optical soliton solutions of a conformable nonlinear Schrödinger equation

Қарағанды университетінің хабаршысы. Математика сериясы
In this paper, we study precise and exact traveling wave solutions of the conformable differential nonlinear Schrödinger equation. Then, we transform the given equation into an integer order differential equation by utilizing the wave transformation and

Superradiance and Broadband Emission Driving Fast Electron Dephasing in Open Quantum Systems

Advanced Science, Volume 13, Issue 27, 13 May 2026.
We uncover the physical origin of ultrafast electron dephasing in solid‐state high‐harmonic generation by simulating the Lindblad equation for the dissipative Hubbard model. Coexistence of Dicke superradiance and broadband emission is revealed, whose destructive interference shortens the effective scattering time and provides a unified picture of ...

Influence of Peptide‐Based Chelator Sequences on HER2‐Targeting Radiopeptide

Journal of Peptide Science, Volume 32, Issue 5, May 2026.
Peptide‐based chelator consisting of Cys‐Gly‐Gly‐Gly incorporated into HER2‐targeting rL‐A9 peptide for 99mTc‐labeling. [99mTc]Tc‐CGGG‐rL‐A9 exhibited high binding affinity and tumor uptake and retention. ABSTRACT In our pursuit of developing HER2‐targeting radiolabeled peptides for detection and therapy of HER2‐positive breast cancer, the previously ...

Characterisation of a phylogenetically distinct PL25 family ulvan lyase from a seaweed biomass enriched metagenome

The FEBS Journal, Volume 293, Issue 10, Page 2885-2907, May 2026.
Ulvan is a polysaccharide available from green seaweed with beneficial properties for various applications. The full potential of ulvan requires enzymatic degradation of the polymer, thus producing ulvan oligosaccharides. This study expands the armoury of characterised ulvan lyases.

An Explicit Construction of Kaleidocycles by Elliptic Theta Functions

Studies in Applied Mathematics, Volume 156, Issue 5, May 2026.
ABSTRACT We study a configuration space consisting of ordered points on the two‐dimensional sphere satisfying a system of quadratic constraints. We construct explicit periodic orbits in the configuration space using elliptic theta functions. The constructed orbits simultaneously satisfy semi‐discrete analogues of the modified KdV and sine‐Gordon ...

Are physiological oscillations physiological?

The Journal of Physiology, Volume 604, Issue 9, Page 3672-3693, 1 May 2026.
Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

Quantum Time‐Marching Algorithms for Solving Linear Transport Problems Including Boundary Conditions

International Journal for Numerical Methods in Engineering, Volume 127, Issue 8, 30 April 2026.
ABSTRACT This article presents the first complete application of a quantum time‐marching algorithm for simulating multidimensional linear transport phenomena with arbitrary boundaries, whereby the success probabilities are problem intrinsic. The method adapts the linear combination of unitaries algorithm to block encode the diffusive dynamics, while ...
