From Photoalignment to Structured Light: Liquid Crystal Platforms for Beam Shaping and Complex Wavefronts

open access: yesAdvanced Functional Materials, EarlyView.
Photoaligned and photopatterned liquid crystal platforms provide programmable control of optical phase, polarization, and spin‐orbit interactions, enabling compact generation of structured light and complex wavefronts. This review highlights how tailored molecular orientations transform simple beams into designed optical fields, opening versatile ...

Special rays and structures in general optical systems: generalized magnifications associated with the fundamental properties

open access: yesAfrican Vision and Eye Health, 2010
In aprevious study special rays and structures, including nodal, principal and focal rays and structures, were defined in terms of generalized magnification of reduced inclination of rays across thesystem.  The mathematical structure of the transference,

C1 neurons: a nodal point for stress? [PDF]

open access: yesExperimental Physiology, 2017
New Findings What is the topic of this review? The C1 neurons (C1) innervate sympathetic and parasympathetic preganglionic neurons plus numerous brain nuclei implicated in stress, arousal and autonomic regulations. We consider here the contribution of C1 to stress‐induced responses. What advances does it highlight?

Impact of Disorder on Microscopic Superconducting and Normal‐State Responses in a Kagome Metal

open access: yesAdvanced Functional Materials, EarlyView.
Using depth‐resolved, field‐ and pressure‐dependent μSR$\umu{\rm SR}$ measurements, we show that disorder in Ta‐doped KV3Sb5 drives a crossover from nodal to nodeless superconductivity while strongly modifying the normal‐state magnetic response. Our results reveal that disorder affects superconductivity and magnetism in fundamentally different ways ...

Correlations in non-Hermitian systems and diagram techniques for the steady state

open access: yesPhysical Review Research, 2020
I construct a diagrammatic technique for non-Hermitian fermionic systems which allows addressing correlation effects in the steady state by systematic expansion.

Topology‐Orchestrated Multi‐physical Energy Control in Turtle Shell‐Inspired Metamaterials

open access: yesAdvanced Materials, EarlyView.
A turtle shell‐inspired lattice metamaterial efficiently manages acoustic, fluid‐thermal, and mechanical energy flows simultaneously. The unique hybrid‐coupling architecture achieves superior sound attenuation via pore‐cavity resonance, facilitates effective airflow transport, and maximizes mechanical energy absorption through multistage cell ...

The Inverse Nodal problem for the fractional diffusion equation

open access: yesActa Scientiarum: Technology, 2015
In this paper, on a general finite interval, the inverse problem of recovering the potential function for a fractional diffusion equation with new spectral parameter, called the nodal point, is given.

Phononic nodal point in two dimensions: A mini-review

open access: yesFrontiers in Physics, 2022
In recent decades, nodal point states in electronic systems have attracted significant interest in current research. Recently, the conceptual framework of nodal point states has been extended to bosonic systems, especially the phononic one.

Imide Substitution Drives the Supramolecular Assembly of Perylene Diimide Into Laterally Modulated Metallic/Semiconducting Molecular Patterns

open access: yesAdvanced Materials Interfaces, EarlyView.
Imide substitution with bulky 2,6‐isopropylphenyl groups induces perylene diimide to self‐assemble on Ag(111) into a monolayer with two coexisting adsorption heights. Molecules closer to the substrate gain metallic character due to charge transfer from the metal, while farther ones remain decoupled and semiconducting.
