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…
