Phenomenological analysis of transverse thermoelectric generation and cooling performance in magnetic/thermoelectric hybrid systems
Kaoru Yamamoto, Ryo Iguchi, Asuka Miura +4
We phenomenologically calculate the performance of the recently-observed Seebeck-driven transverse thermoelectric generation (STTG) for various systems in terms of the thermopower,…
Above-room-temperature giant thermal conductivity switching in spintronic multilayer
Hiroyasu Nakayama, Bin Xu, Sotaro Iwamoto +8
Thermal switching provides an effective way for active heat flow control, which has recently attracted increasing attention in terms of nanoscale thermal management technologies. I…
Machine learning analysis of tunnel magnetoresistance of magnetic tunnel junctions with disordered MgAl2O4
Shenghong Ju, Yoshio Miura, Kaoru Yamamoto +3
Through Bayesian optimization and the least absolute shrinkage and selection operator (LASSO) technique combined with first-principles calculations, we investigated the tunnel magn…
Strain-induced enhancement of the Seebeck effect in magnetic tunneling junctions via interface resonant tunneling: Ab-initio study
Kaoru Yamamoto, Keisuke Masuda, Ken-ichi Uchida +1
We investigate the thermoelectric properties of Fe/MgO/Fe(001) magnetic tunnel junctions (MTJs) by means of the linear-response theory combined with a first-principles-based Landau…
Thermoelectricity near Anderson localization transitions
Kaoru Yamamoto, Amnon Aharony, Ora Entin-Wohlman +1
The electronic thermoelectric coefficients are analyzed in the vicinity of one and two Anderson localization thresholds in three dimensions. For a single mobility edge, we correct…
Polarization selectivity of charge localization induced by 7-fs nearly single-cycle light-field in an organic metal
Y. Kawakami, Y. Yoneyama, T. Amano +9
Polarization selectivity of light-field-induced charge localization was investigated in an organic metal alpha-(BEDT-TTF)2I3 with a triangular lattice. Dependences of transient ref…
Efficiency bounds on thermoelectric transport in magnetic fields: The role of inelastic processes
Kaoru Yamamoto, Ora Entin-Wohlman, Amnon Aharony +1
We examine the efficiency of an effective two-terminal thermoelectric device under broken time-reversal symmetry. The setup is derived from a three-terminal thermoelectric device c…
Optical freezing of charge motion in an organic conductor
Takahiro Ishikawa, Yuto Sagae, Yota Naitoh +10
Dynamical localization, i.e., reduction of the intersite electronic transfer integral t by an alternating electric field, E(omega) , is a promising strategy for controlling strongl…
Thermodynamics of Mesoscopic Quantum Systems
Kaoru Yamamoto
In the present thesis, we study the heat flow in mesoscopic one-dimensional transport systems. Using the analysis of full counting statistics, we calculate the cumulant generating…
Thermodynamics of the mesoscopic thermoelectric heat engine beyond the linear-response regime
Kaoru Yamamoto, Naomichi Hatano
Mesoscopic thermoelectric heat engine is much anticipated as a device that allows us to utilize with high efficiency wasted heat inaccessible by conventional heat engines. However,…
