Predicting molecular dipole moments by combining atomic partial charges and atomic dipoles

Michele Ceriotti, David Mark Wilkins, Max David Veit

The molecular dipole moment (mu) is a central quantity in chemistry. It is essential in predicting infrared and sum-frequency generation spectra as well as induction and long-range electrostatic interactions. Furthermore, it can be extracted directly-via t ...

Universal noise in continuous transport measurements of interacting fermions

Jean-Philippe Brantut

We propose and analyze continuous measurements of atom number and atomic currents using dispersive probing in an optical cavity. For an atom-number measurement in a closed system, we relate both the detection noise and the heating rate due to measurement b ...

Non-reciprocal magnons in non-centrosymmetric MnSi

Thomas Alois Weber, Gregory Scott Tucker

Using two cold-neutron triple-axis spectrometers we have succeeded in fully mapping out the field-dependent evolution of the non-reciprocal magnon dispersion relations in all magnetic phases of MnSi. The non-reciprocal nature of the dispersion manifests it ...

The mouse genome displays highly dynamic populations of KRAB-zinc finger protein genes and related genetic units

Didier Trono, Julien Léonard Duc, Michaël Imbeault, Marco Cassano, Gabriela Ecco, Annamaria Kauzlaric

KRAB-containing poly-zinc finger proteins (KZFPs) constitute the largest family of transcription factors encoded by mammalian genomes, and growing evidence indicates that they fulfill functions critical to both embryonic development and maintenance of adul ...

Imaging and manipulation of skyrmion lattice domains in Cu2OSeO3

Helmuth Berger

Nanoscale chiral skyrmions in noncentrosymmetric helimagnets are promising binary state variables in high-density, low-energy nonvolatile memory. Skyrmions are ubiquitous as an ordered, single-domain lattice phase, which makes it difficult to write informa ...
