Anharmonic Nuclear Motion and the Relative Stability of Hexagonal and Cubic ice
Physical Review X, 2015 We use extensive first-principles quantum mechanical calculations to show that, although the static lattice and harmonic vibrational energies are almost identical, the anharmonic vibrational energy of hexagonal ice is significantly lower than that of ...

Epitaxy and Phase Stability of 2D Hexagonal Gallium Telluride on Silicon
physica status solidi (RRL) – Rapid Research Letters, EarlyView.Two‐stage amorphization as a function of annealing temperature of continuous, strain‐free, high‐crystalline‐quality 2D hexagonal gallium telluride on silicon obtained by van der Waals epitaxy. Controlling crystal quality during epitaxial growth is essential for the advancement of novel materials with industrial relevance.

Substitutional Sulfur and Its Vibrational Fingerprints in Sb2Se3
physica status solidi (RRL) – Rapid Research Letters, EarlyView.The microscopic configurations of sulfur incorporated into the Sb2$_2$Se3$_3$ lattice are studied by combining infrared absorption spectroscopy with density functional theory. Substitutional SSe$_{\mathrm{Se}}$ defects are identified as the origin of four distinct sulfur‐related local vibrational modes at 249, 273, 283, and 312 cm−1$^{-1}$.

Blinking Optical Tweezers for Atom Rearrangements
Advanced Quantum Technologies, EarlyView.The work introduces an energy‐efficient method for holding and rearranging an N ×$\times$ M array of atoms using only N optical tweezers, using just 1M of the optical power per atom. In the proof‐of‐concept experiments, single blinking tweezer holds M = 9 atoms and further facilitates rearrangement M = 4 ∼$\sim$ 5 atoms in various configurations ...

Tunable Josephson Generator for Qubit Excitation and Two‐Tone Spectroscopy
Advanced Quantum Technologies, EarlyView.A tunable on‐chip Josephson generator that enables direct qubit excitation has been presented. The device consists of a current‐biased Josephson junction and a superconducting resonator, forming a microwave source that operates at 4 K. Excitation of the qubit at 20 mK was done via a short coaxial line between the 4 K and 20 mK stages.
