Real-space imaging of σ-hole by means of Kelvin probe force microscopy with subatomic resolution

B. Mallada1, A. Gallardo, M. Lamanec +4

An anisotropic charge distribution on individual atoms, such as e.g. σ-hole, may strongly affect material and structural properties of systems. Nevertheless, subatomic resolution o…

Enhanced sensitivity to a possible variation of the proton-to-electron mass ratio in ammonia

Alec Owens, Sergei N. Yurchenko, Walter Thiel +1

Numerous accidental near-degeneracies exist between the $2 ν_{2}$ and $ν_{4}$ rotation-vibration energy levels of ammonia. Transitions between these two states possess significantly enh…

Accurate prediction of H $_{3}$ O $^{+}$ and D $_{3}$ O $^{+}$ sensitivity coefficients to probe a variable proton-to-electron mass ratio

Alec Owens, Sergei N. Yurchenko, Oleg L. Polyansky +3

The mass sensitivity of the vibration-rotation-inversion transitions of H $_{3}^{16}$ O $^{+}$ , H $_{3}^{18}$ O $^{+}$ , and D $_{3}^{16}$ O $^{+}$ is investigated variationally using the nuclear…
