Searching for Majorana quasiparticles at vortex cores in iron-based superconductors
Tadashi Machida, Tetsuo Hanaguri
The unambiguous detection of the Majorana zero mode (MZM), which is essential for future topological quantum computing, has been a challenge in recent condensed matter experiments.…
Imaging Josephson Vortices on Curved Junctions
Yuita Fujisawa, Anjana Krishnadas, Barnaby R. M. Smith +5
Understanding the nature of vortices in type-II superconductors is crucial for comprehending exotic superconductors and advancing the application of superconducting materials in fu…
Anomalous vortex shape in a frustrated superconductor hosting chiral multicomponent order parameters
Yuita Fujisawa, Anjana Krishnadas, Tomonori Nakamura +12
Multicomponent chiral superconductors can host spatially separated superconducting components within a single Abrikosov vortex, leading to unconventional, anisotropic vortex shapes…
Zeeman effects on Yu-Shiba-Rusinov states
T. Machida, Y. Nagai, T. Hanaguri
When the exchange interaction between the impurity spin and the spins of itinerant quasiparticles are strong or weak enough, the ground states for a magnetic impurity in a supercon…
Quasiparticle Nodal Plane in the Fulde-Ferrell-Larkin-Ovchinnikov State of FeSe
S. Kasahara, H. Suzuki, T. Machida +8
The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state, characterized by Cooper pairs condensed at finite momentum, has been a long-sought state that remains unresolved in many classes…
A scanning tunneling microscope for spectroscopic imaging below 90 mK in magnetic fields up to 17.5 T
T. Machida, Y. Kohsaka, T. Hanaguri
We describe the development and performance of an ultra-high vacuum scanning tunneling microscope working under combined extreme conditions of ultra-low temperatures and high magne…
