Parity Violation in a Single Domain of Spin-Triplet Sr2RuO4 Superconductors
H. Nobukane, K. Inagaki, K. Ichimura +8
We observed an unconventional parity-violating vortex in single domain Sr2RuO4 single crystals using a transport measurement. The current-voltage characteristics of submicron Sr2Ru…
Incommensurate Chiral CDW in -VSe
Y. Sugawara, A. Nomura, Y. Toda +5
We have investigated the chiral charge-density wave (CDW) in -VSe using scanning tunneling microscopy (STM) measurements and optical polarimetry measurements. With the STM…
Possibility of Macroscopic resonant Tunneling near the Superconductor- Insulator Transition in YBaCuO Thin Films
S. Tanda, K. Kagawa, T. Maeno +4
Experimental results of I-V characteristics near the superconductor-insulator transition observed for disorder-tuned YBaCuO thinfilms are presented. The I-V characteristics exibit…
Duality Breaking of Vortex Configuration in a Hierarchical Honeycomb Network
S. Tsuchiya, T. Toshima, H. Nobukane +2
We report measurements of Little-Parks oscillation on the hierarchical honeycomb-superconducting network for investigating possible effects of hierarchical structure in terms of sp…
Charge-Density Waves of Single and Double NbS Chains
S. Tanda, S. Kashimoto, H. Yamamoto +3
The physics of a genuine one-dimensional system in which electrons are confined in one direction remains unclear. The actual electronic state of such a genuinely one-dimensional sy…
Charge density wave soliton liquid
T. Matsuura, J. Hara, K. Inagaki +3
We investigate the charge density wave transport in a quasi-one-dimensional conductor, orthorhombic tantalum trisulfide (-TaS), by applying a radio-frequency ac voltage. We…
Time Operators and Time Crystals
K. Nakatsugawa, T. Fujii, A. Saxena +1
We investigate time operators in the context of quantum time crystals in ring systems. A generalized commutation relation called the generalized weak Weyl relation is used to deriv…
Coexistence of the Kondo effect and spin glass physics in Fe-doped NbS
H. Nobukane, Y. Tabata, T. Kurosawa +2
We report the coexistence of the Kondo effect and spin glass behavior in Fe-doped NbS single crystals. The FeNbS shows the resistance minimum and negative magnetoresist…
Chiral charge-density-waves
J. Ishioka, Y. H. Liu, K. Shimatake +5
We discovered the chirality of charge density waves (CDW) in 1T-TiSe by using scanning tunnelling microscopy (STM) and optical ellipsometry. We found that the CDW intensity bec…
Magic thickness of 25 Ã makes periodic metal-insulator transitions
M. Sakoda, H. Nobukane, S. Shimoda +1
Novel quantum phenomena, including high-temperature superconductivity, topological properties, and charge/spin density waves, appear in low-dimensional conductive materials. It is…
Superconducting networks with the proximity effect
S. Tsuchiya, S. Tanda
We report on the first observation of a novel type of superconducting proximity network using a superconductor-normal metal bilayer. Little-Parks oscillation measurements show that…
Quenching of phase coherence in quasi-one dimensional ring crystals
K. Shimatake, Y. Toda, S. Tanda
The comparison of the single-particle (SP) dynamics between the whisker and ring NbSe crystals provides new insight into the phase transition properties in quasi-one-dimensiona…
