Characteristics of the Mott transition and electronic states of high-temperature cuprate superconductors from the perspective of the Hubbard model
Masanori Kohno
A fundamental issue of the Mott transition is how electrons behaving as single particles carrying spin and charge in a metal change into those exhibiting separated spin and charge…
Mott transition and electronic excitation of the Gutzwiller wavefunction
Masanori Kohno
The Mott transition is usually considered as resulting from the divergence of the effective mass of the quasiparticle in the Fermi-liquid theory; the dispersion relation around the…
Emergence and spectral-weight transfer of electronic states in the Hubbard ladder
Masanori Kohno
The number of electronic bands is usually considered invariant regardless of the electron density in a band picture. However, in interacting systems, the spectral-weight distributi…
Thermal algebraic-decay charge liquid driven by competing short-range Coulomb repulsion
Ryui Kaneko, Yoshihiko Nonomura, Masanori Kohno
We explore the possibility of a Berezinskii-Kosterlitz-Thouless-like critical phase for the charge degrees of freedom in the intermediate-temperature regime between the charge-orde…
States induced in the single-particle spectrum by doping a Mott insulator
Masanori Kohno
In strongly correlated electron systems, the emergence of states in the Mott gap in the single-particle spectrum following the doping of the Mott insulator is a remarkable feature…
Spectral properties near the Mott transition in the two-dimensional t-J model
Masanori Kohno
The single-particle spectral properties of the two-dimensional t-J model in the parameter regime relevant to cuprate high-temperature superconductors are investigated using cluster…
