Singlet polaron theory of low-energy optical excitations in NiPS
I. J. Hamad, C. S. Helman, L. O. Manuel +2
Light-matter interactions can be used as a tool to realize novel many-body states of matter and to study the interplay between electronic and magnetic degrees of freedom. In partic…
Theory of differential conductance of Co on Cu(111) including Co s and d orbitals, and surface and bulk Cu states
J. Fernandez, P. Roura-Bas, A. A. Aligia
We revisit the theory of the Kondo effect observed by a scanning-tunneling microscope (STM) for transition-metal atoms (TMAs) on noble-metal surfaces, including and orbital…
Calculation of the four-spin cyclic exchange in cuprates
A. A. Aligia
Starting from the three-band Hubbard model for the cuprates, we calculate analytically the four-spin cyclic exchange in the limit of infinite on-site Coulomb repulsion and zero O-O…
Quantifying the leading role of the surface state in the Kondo effect of Co/Ag(111)
M. Moro-Lagares, J. Fernández, P. Roura-Bas +3
Using a combination of scanning tunneling spectroscopy and atomic lateral manipulation, we obtained a systematic variation of the Kondo temperature () of Co atoms on A…
Many-body dynamics of the decay of excitons of different charges in a quantum dot
J. A. Andrade, A. A. Aligia, Pablo S. Cornaglia
We calculate the photoluminescence spectrum of a single semiconductor quantum dot strongly coupled to a continuum as a function of light frequency, gate voltage, and magnetic field…
Scaling of conductance through quantum dots with magnetic field
I. J. Hamad, C. Gazza, J. A. Andrade +3
Using different techniques, and Fermi-liquid relationships, we calculate the variation with applied magnetic field (up to second order) of the zero-temperature equilibrium conducta…
