We report on the optical spectroscopy of a single InAs/GaAs quantum dot doped with a single Mn atom in a longitudinal magnetic field of a few Tesla. Our findings show that the Mn impurity is a neutral acceptor state A0 whose effective spin J=1 is significantly perturbed by the quantum dot potential and its associated strain field. The spin interaction with photocarriers injected in the quantum dot is shown to be ferromagnetic for holes, with an effective coupling constant of a few hundreds of… Expand
Optical control of a Mn spin embedded in a quantum dot
We demonstrate a high degree of an optical spin preparation of a single Mn atom embedded in a CdTe/ZnTe quantum dot (QD). Due to the strong exchange interaction of the manganese atom with an excitonExpand
Spin state of a single Mn atom embedded in an InAs quantum dot
The spin states of single Mn atoms embedded in InAs quantum dots (QD) were investigated by optical means. In (In,Ga)As, the Mn impurity acts both as acceptor and a magnetic moment. In the low densityExpand
Optical spin orientation of a single manganese atom in a quantum dot
The magnetic state of a single magnetic atom (Mn) embedded in an individual semiconductor quantum dot is optically probed using micro-spectroscopy. A high degree of spin polarization can be achievedExpand
Dynamics of a single Mn spin in a quantum dot: The role of magnetic fields in Faraday and Voigt geometry
A theoretical analysis of the optically driven spin dynamics of a single Mn atom in a quantum dot in the presence of magnetic fields in different geometries is presented. When a magnetic field inExpand
Optical probing of the spin state of a single magnetic atom in a quantum dot
Abstract The magnetic state of a single magnetic ion (Mn 2+ ) embedded in an individual quantum dot is optically probed using microspectroscopy. The fine structure of a confined exciton in theExpand
Optical orientation of a single Mn spin in a quantum dot: Role of carrier spin relaxation
In order to explain the recently observed phenomenon of optical orientation of a single Mn spin residing inside a CdTe quantum dot, a process of Mn spin relaxation with characteristic time scale ofExpand

TLDR
Successful doping of colloidal CdSe quantum dots with a very small number of manganese ions-down to the ultimate limit of one is reported, opening a path for solotronic applications at elevated temperatures. Expand
Optical control of the spin of a magnetic atom in a semiconductor : hybrid hole-Manganese spin and Chromium spin
Two different single spin systems are studied in this thesis: single Mn spin in positively charged quantum dots, and single Cr atom in a neutral quantum dots. Both are probed optically, using theExpand
Optically controlled spin dynamics in a magnetically doped quantum dot
The optically induced spin dynamics in a single quantum dot doped with a single Mn atom are studied theoretically both for the case of a magnetic field applied in Faraday configuration and in VoigtExpand
All-optical spin switching in neutral or charged magnetic quantum dots
The spin dynamics in a single semiconductor quantum dot doped with a single Mn atom are analyzed. We consider a neutral and a negatively charged dot and in both cases we concentrate on the lightExpand

TLDR
I am writing with a simple plea to balance the voluminous articles about treatment in your journal with a modicum of information about nature and caring effects to rekindle the perception of physicians as healers, not only treaters, who relish the gifts of nature, and foster the humanistic aspect of medicine that has thrived for millennia.
