Occurrence control of charged exciton for a single CdSe quantum dot at cryogenic temperatures on an optical nanofiber
K. Muhammed Shafi, Kazunori Iida, Emi Tsutsumi +2
We discuss photo-luminescence characteristics of CdSe core/shell quantum dots at cryogenic temperatures using a hybrid system of a single quantum dot and an optical nanofiber. The…

Efficient fiber in-line single photon source based on colloidal single quantum dots on an optical nanofiber
K. Muhammed Shafi, Kali P. Nayak, Akiharu Miyanaga +1
We demonstrate a fiber in-line single photon source based on a hybrid system of colloidal single quantum dots deposited on an optical nanofiber and cooled down to cryogenic tempera…

Orientational symmetry-breaking correlations in square lattice t-J model
Akiharu Miyanaga, Hiroyuki Yamase
We study a tendency to orientational symmetry breaking of the square lattice t-J model by applying the exact diagonalization technique. We introduce a small external anisotropy to…
