The state of optics research in Colombia: a scientometric analysis

Optics research in Colombia has experienced significant growth in the last two decades, with increasing output and citation impact, ranking second in Latin America after Chile. While international collaboration plays a vital role in the high impact of Colombian optics research, there's a need to increase the impact of research led by Colombian researchers themselves.

Velocity effect on the stimulated transition process of a multilevel atom in a thermal bath

The study calculates the stimulated emission and absorption rates of a uniformly moving atom in a thermal bath of quantum electromagnetic radiation, finding these rates depend on atomic velocity, bath temperature, and atomic polarizability. This suggests the temperature of the quantum electromagnetic field is relative and observer-dependent, similar to the Unruh effect, but with directional temperature variations depending on the atom's polarizability.

Coherent control techniques in three-level quantum sensing

This paper proposes using composite pulse sequences in three-level quantum systems to amplify the effects of small Rabi frequency and detuning errors, enabling their detection. By repeatedly applying control pulses with specific phases, the sensitivity to these errors is increased, potentially improving quantum sensing capabilities.

Recent developments in the general atomic and molecular electronic structure system

This paper details substantial updates and additions to the quantum chemistry software GAMESS, including fragmentation methods, coupled cluster improvements, density functional updates, and increased utilization of graphical processing units (GPUs) and other parallel computing strategies. These enhancements aim to improve the performance, scalability, and overall usability of the software for studying larger molecular systems.
