Thermally assisted Pauli spin blockade in double quantum dots
M. Kondo, S. Miyota, W. Izumida +2
We investigate the influence of thermal energy on the current flow and electron spin states in double quantum dots in series. The quadruplet Pauli spin blockade, which is caused by…
Topologically protected, correlated end spin formation in carbon nanotubes
Cătălin Paşcu Moca, Wataru Izumida, Balázs Dóra +3
For most chiralities, semiconducting nanotubes display topologically protected end states of multiple degeneracies. We demonstrate using density matrix renormalization group based…
Topological classification of the single-wall carbon nanotube
Rin Okuyama, Wataru Izumida, Mikio Eto
The single-wall carbon nanotube (SWNT) can be a one-dimensional topological insulator, which is characterized by a -topological invariant, winding number. Using the ana…
Transverse profile and 3D spin canting of a Majorana state in carbon nanotubes
Lars Milz, Wataru Izumida, Milena Grifoni +1
The full spatial 3D profile of Majorana bound states (MBS) in a nanowire-like setup featuring a semiconducting carbon nanotube (CNT) as the central element is discussed. By accurat…
Topology and zero energy edge states in carbon nanotubes with superconducting pairing
W. Izumida, L. Milz, M. Marganska +1
We investigate the spectrum of finite-length carbon nanotubes in the presence of onsite and nearest-neighbor superconducting pairing terms. A one-dimensional ladder-type lattice mo…
Angular momentum and topology in semiconducting single-wall carbon nanotubes
W. Izumida, R. Okuyama, A. Yamakage +1
Semiconducting single-wall carbon nanotubes are classified into two types by means of orbital angular momentum of valley state, which is useful to study their low energy electronic…
