Functional-renormalization-group approach to classical liquids with short-range repulsion: a scheme without repulsive reference system
Takeru Yokota, Jun Haruyama, Osamu Sugino
The renormalization-group approaches for classical liquids in previous works require a repulsive reference such as a hard-core one when applied to systems with short-range repulsio…
Ab initio construction of the energy density functional for electron systems with the functional-renormalization-group-aided density functional theory
Takeru Yokota, Tomoya Naito
We show an construction of the energy density functional (EDF) for electron systems using the functional renormalization group. The correlation energies of the…
Functional-renormalization-group aided density-functional analysis for the correlation energy of the two-dimensional homogeneous electron gas
Takeru Yokota, Tomoya Naito
The functional-renormalization-group aided density-functional theory (FRG-DFT) is applied to the two-dimensional homogeneous electron gas (2DHEG). The correlation energy of the 2DH…
Ab-initio description of excited states of a one-dimensional nuclear matter with the Hohenberg-Kohn-theorem-inspired functional-renormalization-group method
Takeru Yokota, Kenichi Yoshida, Teiji Kunihiro
We demonstrate for the first time that a functional-renormalization-group aided density-functional theory (FRG-DFT) describes well the characteristic features of the excited states…
Functional renormalization-group calculation of the equation of state of one-dimensional nuclear matter inspired by the Hohenberg--Kohn theorem
Takeru Yokota, Kenichi Yoshida, Teiji Kunihiro
We present the first successful functional renormalization group(FRG)-aided density-functional (DFT) calculation of the equation of state (EOS) of an infinite nuclear matter (NM) i…
Tachyonic instability of the scalar mode prior to QCD critical point based on Functional renormalization-group method
Takeru Yokota, Teiji Kunihiro, Kenji Morita
We establish and elucidate the physical meaning of the appearance of an acausal mode in the sigma mesonic channel, found in the previous work by the present authors, when the syste…
