Semiconductor Nanopillar as a Single-Photon Emitter and its Optimal Design
S. Odashima, H. Sasakura
The semiconductor quantum dot nanopillar array in InAs/GaAs was fabricated. In consideration of the quantum dot density, the pillar diameter was determined as only a few quantum do…
Fiber-coupled pillar array as a highly pure and stable single-photon source
Satoru Odashima, Hirotaka Sasakura, Hideaki Nakajima +1
A highly pure and stable single-photon source is prepared that comprises a well-designed pillar array in which each pillar contains only a few InAs quantum dots. A nano-pillar in t…
Bidirectional photon extraction from an epitaxially grown semiconductor quantum dot sandwiched by single mode optical fibers
H. Sasakura, X. Liu, S. Odashima +3
Fiber-based bidirectional photon extraction from nanoscale emitters and photon antibunching behavior between two outputs of two single mode optical fibers are experimentally demons…
The two-orbital Hubbard model and the OSMT
Adolfo Avella, Ferdinando Mancini, Satoru Odashima +1
We analyze the two-orbital Hubbard model by means of the Composite Operator Method with the aim at studying the phenomenon of orbital selective Mott transition (OSMT). The model co…
High-order correlation effects in the two-dimensional Hubbard model
Satoru Odashima, Adolfo Avella, Ferdinando Mancini
The electronic states of the two-dimensional Hubbard model are investigated by means of a 4-pole approximation within the Composite Operator Method. In addition to the conventional…
4-pole analysis of the two-dimensional Hubbard model
Satoru Odashima, Adolfo Avella, Ferdinando Mancini
The electronic states of the two-dimensional Hubbard model are investigated by means of a 4-pole approximation within the Composite Operator Method. In addition to the conventional…
