Systematic study of superconductivity in few-layer -MoTe
Taro Wakamura, Masayuki Hashisaka, Yusuke Nomura +7
We present a systematic investigation of superconductivity in a topological superconductor candidate -MoTe in the few-layer limit. By examining multiple mechanically…
Uniform Narrow Excitonic Spectrum in Large-Area Suspended WSe2 Monolayers
Giacomo Mariani, Riccardo Lodo, Keigo Matsuyama +7
Uniformity in the excitonic spectrum is a key requirement for accessing intrinsic excitonic physics in two-dimensional semiconductors; however, in transition-metal dichalcogenide (…
Intrinsic ultrafast edge photocurrent dynamics in WTe driven by broken crystal symmetry
Subhashri Chatterjee, Katsumasa Yoshioka, Taro Wakamura +2
Directional photocurrents in two-dimensional materials arise from broken crystal symmetry, offering pathways to high-speed, bias-free photodetection beyond conventional devices. Tu…
Efficient heat-energy conversion from a non-thermal Tomonaga-Luttinger liquid
Hikaru Yamazaki, Masashi Uemura, Haruhi Tanaka +5
Energy harvesting is a technique that generates useful work from waste heat. Conventional energy harvesters acting on local thermal equilibrium states are constrained by thermodyna…
Coulomb-mediated single-electron heat transfer statistics across capacitively coupled silicon nanodots
Kensaku Chida, Antoine Andrieux, Katsuhiko Nishiguchi
Heat transfer mediated by the Coulomb interaction reveals unconventional thermodynamic behavior and broadens thermodynamics research into fields such as quantum dynamics and inform…
Residual gauge theory for quanta of surface plasmons
Ken-ichi Sasaki
We develop a gauge-theoretical framework to investigate the quanta of surface plasmons. Our formulation, based on quantum electrodynamics, highlights the importance of residual gau…
