Chirality in bare and ligand-protected metal nanoclusters

Advances in Physics: X, 2018
Chirality is a fundamental property of matter with profound impact in physics, chemistry, biology, and medicine. It is present at several scales going from elementary particles, to molecules, to macroscopic materials, and even to astronomical objects ...

The role of chirality and plastic crystallinity in the optical and mechanical properties of chlorosomes

iScience, 2022
Summary: The most efficient light-harvesting antennae found in nature, chlorosomes, are molecular tubular aggregates (TMAs) assembled by pigments without protein scaffolds.

Chiral nature of magnetic monopoles in artificial spin ice

New Journal of Physics, 2013
Micromagnetic properties of monopoles in artificial kagome spin ice systems are investigated using numerical simulations. We show that micromagnetics brings additional complexity into the physics of these monopoles that is, by essence, absent in spin ...

Single Photon Approach for Chirality Sensing

Photonics, 2023
We developed a high sensitivity optical sensor for circular birefringence using a heralded photon source. The sensor can be employed for chirality measurements and, being based on single photons, can be exploited for fragile biological sample or in ...

Chiral vortons and cosmological constraints on particle physics [PDF]

Physical Review D, 2000
We investigate the cosmological consequences of particle physics theories that admit stable loops of current-carrying string - vortons. In particular, we consider chiral theories where a single fermion zero mode is excited in the string core, such as those arising in supersymmetric theories with a D-term.

A quantum physics layer of epigenetics: a hypothesis deduced from charge transfer and chirality-induced spin selectivity of DNA

Clinical Epigenetics, 2023
Background Epigenetic mechanisms are informational cellular processes instructing normal and diseased phenotypes. They are associated with DNA but without altering the DNA sequence. Whereas chemical processes like DNA methylation or histone modifications
