Vortex dynamics in the two-dimensional BCS-BEC crossover
Max Heyl, Kyosuke Adachi, Yuki M. Itahashi +5
The Bardeen-Cooper-Schrieffer (BCS) condensation and Bose-Einstein condensation (BEC) are the two limiting ground states of paired Fermion systems, and the crossover between these…
Stabilization of vortex-liquid state by strong pairing interaction
Kyosuke Adachi, Ryusuke Ikeda
We theoretically investigate qualitative features of the field-temperature (-) phase diagram of superconductors with strong attractive interaction lying in the BCS-BEC crosso…
Dimensionality-induced BCS-BEC crossover in layered superconductors
Kyosuke Adachi, Ryusuke Ikeda
Based on a simple model of a layered superconductor with strong attractive interaction, we find that the separation of the pair-condensation temperature from the pair-formation tem…
Enhanced superconducting-fluctuation effects on thermodynamic properties in BCS-BEC-crossover regime
Kyosuke Adachi, Ryusuke Ikeda
Effects of superconducting fluctuation (SCF) on thermodynamic properties of electron systems in the so-called BCS-BEC-crossover regime are studied. As the attractive interaction be…
Fluctuation Diamagnetism in Two-Band Superconductors
Kyosuke Adachi, Ryusuke Ikeda
Anomalously large fluctuation diamagnetism around the superconducting critical temperature has been recently observed on iron selenide (FeSe) [S. Kasahara et al., unpublished]. Thi…
Possible Field-Temperature Phase Diagrams of Two-Band Superconductors with Paramagnetic Pair-Breaking
Kyosuke Adachi, Ryusuke Ikeda
Possible field-temperature superconducting (SC) phase diagrams in two-band quasi-two-dimensional materials with a strong paramagnetic pair-breaking (PPB) are considered theoretical…
