Electromagnetic response of a metamaterial with field-gradient-induced transparency
Yasuhiro Tamayama, Toshihiro Nakanishi, Yasuhiro Wakasa +3
We investigate a dynamically controllable electromagnetically induced transparency-like metamaterial. The unit structure of the metamaterial consists of a low-quality-factor resona…
Direct observation of geometric phases using a three-pinhole interferometer
H. Kobayashi, S. Tamate, T. Nakanishi +2
We present a method to measure the geometric phase defined for three internal states of a photon (polarizations) using a three-pinhole interferometer. From the interferogram, we ca…
Observation of geometric phases in quantum erasers
H. Kobayashi, S. Tamate, T. Nakanishi +2
We introduce a simple experiment involving a double-slit interferometer by which one can learn basic concepts of quantum interference such as which-path marking, quantum erasers, a…
Full Quantum Analysis of Two-Photon Absorption Using Two-Photon Wavefunction: Comparison with One-Photon Absorption
Toshihiro Nakanishi, Hirokazu Kobayashi, Kazuhiko Sugiyama +1
For dissipation-free photon-photon interaction at the single photon level, we analyze one-photon transition and two-photon transition induced by photon pairs in three-level atoms u…
Geometrical aspects of weak measurements and quantum erasers
Shuhei Tamate, Hirokazu Kobayashi, Toshihiro Nakanishi +2
We investigate the mechanism of weak measurement by using an interferometric framework. In order to appropriately elucidate the interference effect that occurs in weak measurement,…
Two-photon interference of photon pairs created in photonic crystal fibers
Toshihiro Nakanishi, Kazuo Sakemi, Hirokazu Kobayashi +2
We investigate a method to produce photon pairs by four-wave mixing in photonic crystal fibers (PCFs). By controlling the wavelength of the pump light, which determines the phase m…
