A Versatile Materials Class for Solution‐Processed Optics and Photonics Based On Titanium Oxide Hydrates and Polyalcohols: A Perspective

Advanced Materials, EarlyView.
A new, solution‐processable class of optical materials based on molecular hybrids of metal oxide hydrates and commodity polymers is discussed here, including their synthesis, processing into thin films, patterning, and photonic structures realized to date.

Perovskite Microwires for Room Temperature Exciton‐Polariton Neural Network

Advanced Materials, EarlyView.
Exciton‐polaritons are explored as a novel platform for optical neuromorphic computing at room temperature using a monocrystalline perovskite waveguide. Demonstrating non‐equilibrium Bose‐Einstein condensation, this work achieves machine learning tasks such as classification and object detection, marking a key advance toward energy‐efficient, practical

On Linear Hamiltonian Systems [PDF]

MATEC Web of Conferences, 2017
In this paper we consider the normalization of quadratic Hamiltonian. We get the new method to find the generating function of the canonical transformation. We obtain the solution of the system of matrix equations to find this transformation. The corresponding Hamiltonian matrix has multiply eigenvalues.

Electrostatically Enhanced Buried Interface Binding of Self‐Assembled Monolayers for Efficient And Stable Inverted Perovskite Solar Cells

Advanced Materials, EarlyView.
In p‐i‐n structure perovskite solar cells, conventional self‐assembled monolayers (SAMs) such as [2‐(9H‐carbazol‐9‐yl)ethyl]phosphonic acid (2PACz) exhibit limited buried interfacial adhesion, compromising device stability. A donor‐acceptor SAM, 4‐(7‐(4‐(bis(4‐methoxyphenyl)amino‐2,5‐difluorophenyl)benzo[c][1,2,5]thiadiazol‐4‐yl)benzoic acid (PAFTB ...

Existence and concentration of homoclinic orbits for first order Hamiltonian systems

Communications in Analysis and Mechanics
This paper is concerned with the following first-order Hamiltonian system $ \begin{equation} \nonumber \dot{z} = \mathscr{J}H_{z}(t, z), \end{equation} $ where the Hamiltonian function $ H(t, z) = \frac{1}{2}Lz\cdot z+A(\epsilon t)G(|z|) $ and ...

Homoclinic solutions for second order Hamiltonian systems with general potentials near the origin

Electronic Journal of Qualitative Theory of Differential Equations, 2013
In this paper, we study the existence of infinitely many homoclinic solutions for a class of second order Hamiltonian systems with general potentials near the origin. Recent results from the literature are generalized and significantly improved.

Manipulating Individual Topological Solitons and Bisolitons in an Electronic System

Advanced Materials, EarlyView.
While localized topological modes in quantum materials promise loss‐less delivery of classical and quantum information, manipulating them individually has been challenging. This work succeeded in manipulating topological solitons formed along atomic wires on silicon surfaces with high reproducibility in various ways, including translating, transforming

Linear type global centers of cubic Hamiltonian systems symmetric with respect to the x-axis

Electronic Journal of Differential Equations, 2020
A polynomial differential system of degree 2 has no global centers (that is, centers defined in all the plane except the fixed point). In this paper we characterize the global centers of cubic Hamiltonian systems symmetric with respect to the x-axis ...

On periodic differential equations with dissipation

Electronic Journal of Qualitative Theory of Differential Equations, 2018
In this work we present an unexpected relation between the discriminant associated to a Hill equation with and without dissipation. We prove that by knowing the discriminant associated to a periodic differential equation, which is the summation of the ...
