Correlation between Optical Activity and the Helical Molecular Orbitals of Allene and Cumulenes

Helical frontier molecular orbitals (MOs) appear in disubstituted allenes and even-n cumulenes. Chiral molecules are optically active, but while these molecules are single-handed chiral, p-orbitals of both helicities are present. Here we computationally ex ...

Accessible Superchiral Near-Fields Driven by Tailored Electric and Magnetic Resonances in All-Dielectric Nanostructures

Hatice Altug, Andreas Tittl, Yasaman Jahani, Kosmas Tsakmakidis, Ershad Mohammadi

Detection and differentiation of enantiomers in small quantities are crucially important in many scientific fields, including biology, chemistry, and pharmacy. Chiral molecules manifest their handedness in their interaction with the chiral state of light ( ...

Terahertz-optical properties of a bismuth ferrite single crystal

Henrik Moodysson Rønnow, Jean-Philippe Ansermet, Marcin Bialek

Transmission through a (100)-oriented single crystal of bismuth ferrite (BiFeO3) was studied at frequencies of 0.485-0.765 THz with a continuous-wave source and in the temperature range of 30-350 K as a function of polarization angle. The fine splitting of ...

Enhanced Circular Dichroism and Chiral Sensing with Bound States in the Continuum

Hatice Altug, Andreas Tittl, Yasaman Jahani

We reveal that optical chirality at the nanoscale can be boosted dramatically by bound states in the continuum (BIC). We predict the enhancement of chiroptical signals from nanostructures supporting quasi-BICs in mid-IR with a record-high efficiency. (C) 2 ...

Broad-Band Ultraviolet CD Spectroscopy of Ultrafast Peptide Backbone Conformational Dynamics

Majed Chergui, Malte Oppermann, Benjamin Bauer

The far-UV spectral window widely used for the conformational analysis of biomolecules is not easily covered with broad-band lasers. This has made it difficult to use circular dichroism (CD) spectroscopy to directly follow fast structure changes. By combin ...

Nanophotonic Platforms for Enhanced Chiral Sensing

Hatice Altug, Kosmas Tsakmakidis, Ershad Mohammadi

Chirality plays an essential role in life, providing unique functionalities to a wide range of biomolecules, chemicals, and drugs, which makes chiral sensing and analysis critically important. The wider application of chiral sensing continues to be constra ...

Selective Probing of Hidden Spin-Polarized States in Inversion-Symmetric Bulk MoS2

Jan Hugo Dil, Joël Mesot, Stefan Peter Muff, Andrea Pisoni, Mauro Fanciulli, Elia Razzoli, Philipp Aebi

Spin-and angle-resolved photoemission spectroscopy is used to reveal that a large spin polarization is observable in the bulk centrosymmetric transition metal dichalcogenide MoS2. It is found that the measured spin polarization can be reversed by changing ...

Influence of the β-sheet content on the mechanical properties of aggregates during amyloid fibrillization

Giovanni Dietler, Hilal Lashuel, Francesco Simone Ruggeri, Jae Sun Jeong, Raffaele Mezzenga

Amyloid fibrils associated with neurodegenerative diseases, such as Parkinson's and Alzheimer's, consist of insoluble aggregates of α-synuclein and Aβ-42 proteins with a high β-sheet content. The aggregation of both proteins occurs by misfolding of the mon ...
