Tackling multimodal device distributions in inverse photonic design using invertible neural networks

open access: yesMachine Learning: Science and Technology, 2023
We show how conditional generative neural networks can be used to efficiently find nanophotonic devices with desired properties, also known as inverse photonic design.

Effect of titanium-dioxide nanoparticle on Richardson constant and barrier height of tartrazine dye based Schottky device

open access: yesDiscover Materials, 2023
Recently Fruit Dyes have achieved a significant interest as organic devices because of they are widely available, customizable and biodegradable. But low conductivity is one of the major limitations.

THE CONDENSED MATTER PHYSICS OF QCD [PDF]

open access: yes, 2001
Important progress in understanding the behavior of hadronic matter at high density has been achieved recently, by adapting the techniques of condensed matter theory. At asymptotic densities, the combination of asymptotic freedom and BCS theory make a rigorous analysis possible. New phases of matter with remarkable properties are predicted.

Probing condensed matter physics with magnetometry based on nitrogen-vacancy centres in diamond [PDF]

open access: yes, 2018
The magnetic fields generated by spins and currents provide a unique window into the physics of correlated-electron materials and devices. Proposed only a decade ago, magnetometry based on the electron spin of nitrogen-vacancy (NV) defects in diamond is ...

Generalized Symmetries in Condensed Matter [PDF]

open access: yesAnnual Review of Condensed Matter Physics, 2022
Recent advances in our understanding of symmetry in quantum many-body systems offer the possibility of a generalized Landau paradigm that encompasses all equilibrium phases of matter.

Exciton diffusion in two-dimensional metal-halide perovskites

open access: yesNature Communications, 2020
The so-called two-dimensional (2D) layered perovskites possess distinct optoelectronic properties from their 3D counterparts due to their reduced dimensionality. Here Seitz et al. investigate the exciton transport dynamics in 2D perovskites and highlight

Nanoscale inhomogeneity and the evolution of correlation strength in FeSe $$_{1-x}$$ 1 - x S $$_x$$ x

open access: yesNano Convergence, 2023
We report a comprehensive study of the nanoscale inhomogeneity and disorder on the thermoelectric properties of FeSe $$_{1-x}$$ 1 - x S $$_x$$ x ( $$0 \le x \le 1$$ 0 ≤ x ≤ 1 ) single crystals and the evolution of correlation strength with S substitution.

Soft condensed matter physics [PDF]

open access: yesSolid State Communications, 1997
Soft condensed matter physics is the study of materials, such as fluids, liquid crystals, polymers, colloids, and emulsions, that are ``soft" to the touch. This article will review some properties, such as the dominance of entropy, that are unique to soft materials and some properties such as the interplay between broken-symmetry, dynamic mode ...

Few-Body Systems in Condensed Matter Physics [PDF]

open access: yesFew-body systems, 2019
This review focuses on the studies and computations of few-body systems of electrons and holes in condensed matter physics. We analyze and illustrate the application of a variety of methods for description of two- three- and four-body excitonic complexes

Electronic nature of charge density wave and electron-phonon coupling in kagome superconductor KV3Sb5

open access: yesNature Communications, 2022
The impact of the charge density wave (CDW) state to the electronic structure in the Kagome superconductors AV3Sb5 remains unclear. Here, the authors observe CDW-induced Fermi surface reconstruction with a strongly anisotropic CDW gap and signatures of ...
