Franco, A. F. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Landeros, P. (American Physical Society, 2020-11)
Spin-wave-based circuits and logic devices have been considered as an alternative to current electronic devices as they approach the physical limit of miniaturization. Asymmetrical propagation of spin waves, also known as ...

Chougale, Yashwant; Talukdar, Jugal; Ramos, Tomas [Univ Mayor, Fac Estudios Interdisciplinarios, DAiTA Lab, Chile]; Nath, Rejish (American Physical Society, 2020-08)
We study the dynamics of up to two Rydberg excitations and the correlation growth in a chain of atoms coupled to a photonic crystal waveguide. In this setup, an excitation can hop from one atom to another via exponentially ...

M.; Guzmán-Lastra, Francisca [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Loewen, Hartmut; Menzel, Andreas M.; Daddi-Moussa-Ider, Abdallah (Chile. Universidad Mayor, 2020)
Geometric confinements are frequently encountered in the biological world and strongly affect the stability, topology, and transport properties of active suspensions in viscous flow. Based on a far-field analytical model, ...
