g-Factor Enhanced Upper Critical Field in Superconducting PdTe2 due to Quantum Confinement
Kota Yoshimura, Tzu-Chi Hsieh, Huiyang Ma +14
The Pauli limiting field of superconductors determines the maximal possible value of magnetic field at which superconductivity remains possible. For weak-coupling superconductors,…
Deterministic Formation of Single Organic Color Centers in Single-Walled Carbon Nanotubes
Daichi Kozawa, Yuto Shiota, Yuichiro K. Kato
Quantum light sources using single-walled carbon nanotubes show promise for quantum technologies but face challenges in achieving precise control over color center formation. Here…
Strongly hybridized phonons in one-dimensional van der Waals crystals
Shaoqi Sun, Qingyun Lin, Yihuan Li +7
The phenomena of pronounced electron-electron and electron-phonon interactions in one-dimensional (1D) systems are ubiquitous, which are well described by frameworks of Luttinger l…
Intrinsic process for upconversion photoluminescence via -momentum phonon coupling in carbon nanotubes
Daichi Kozawa, Shun Fujii, Yuichiro K. Kato
We investigate the intrinsic microscopic mechanism of photon upconversion in air-suspended single-walled carbon nanotubes through photoluminescence and upconversion photoluminescen…
