Effect of uniform bond-charge order on longitudinal spin-susceptibility jump at a superconducting instability inside a magnetic phase
Sher Baz, Hiroyuki Yamase
A previous work [H. Yamase and M. Zafur, Phys. Rev. B \textbf{103}, 224527 (2021)] showed that the longitudinal spin susceptibility exhibits a jump when the superconductivity devel…
Anisotropic bond-current susceptibilities and real-space current topology in correlated electron systems
Worapon Phatcharasirinawakun, Hiroyuki Yamase
We derive all symmetry-allowed bond-current form factors generated by nearest-neighbor bond-charge interactions on square, triangular, and kagome lattices. We find that the anisotr…
Quantum criticality and non-Fermi liquids: the Wilsonian renormalization group perspective
Mateusz Homenda, Pawel Jakubczyk, Hiroyuki Yamase
We develop a theoretical framework based on the nonperturvative renormalization group (RG) in the one-particle irreducible (Wetterich) formulation to tackle the interplay of couple…
Generalized Hertz action and quantum criticality of two-dimensional Fermi systems
Mateusz Homenda, Paweł Jakubczyk, Hiroyuki Yamase
We reassess the structure of the effective action and quantum critical singularities of two-dimensional Fermi systems characterized by the ordering wavevector . B…
Retaining Landau quasiparticles in the presence of realistic charge fluctuations in cuprates
Hiroyuki Yamase, Matias Bejas, Andres Greco
Charge excitation spectra are getting clear in cuprate superconductors in momentum-energy space especially around a small momentum region, where plasmon excitations become dominant…
Spin and bond-charge excitation spectra in correlated electron systems near antiferromagnetic phase
Muhammad Zafur, Hiroyuki Yamase
Magnetic and bond-charge interactions can arise from the same microscopic interaction. Motivated by this observation, we compute magnetic and bond-charge excitation spectra on an e…
