Physicist solved the puzzle of long ranged interactions between spins in In(Ga)As quantum dots

For a long time, the microscopic mechanism in In(Ga)As quantum dots ensemble was unclear that induces an effective long ranged interaction between the electron spins trapped in quantum dots. A team of theoretical solid-state physicists at the TU Dortmund has been able to solve this long standing puzzle and has published their results in the prestigious journal Physical Review Letters.
