Mobile impurity in a Fermi sea from the functional renormalization group analytically continued to real time
Kazuhiko Kamikado, Takuya Kanazawa, Shun Uchino
Motivated by experiments with cold atoms, we investigate a mobile impurity immersed in a Fermi sea in three dimensions at zero temperature by means of the functional renormalizatio…
Nonperturbative RG analysis of five-dimensional O(N) models with cubic interactions
Kazuhiko Kamikado, Takuya Kanazawa
We reconsider critical properties of O(N) scalar models with cubic interactions in dimensions using functional renormalization group equations. Working at next-to-leading ord…
Phonons, pions and quasi-long-range order in spatially modulated chiral condensates
Yoshimasa Hidaka, Kazuhiko Kamikado, Takuya Kanazawa +1
We investigate low-energy fluctuations in the real kink crystal phase of dense quark matter within the Nambu--Jona-Lasinio model. The modulated chiral condensate breaks both the tr…
Magnetic susceptibility of a strongly interacting thermal medium with 2+1 quark flavors
Kazuhiko Kamikado, Takuya Kanazawa
Thermodynamics of the three-flavor quark-meson model with axial anomaly is studied in the presence of external magnetic fields. The nonperturbative functional renormalization group…
Chiral dynamics in a magnetic field from the functional renormalization group
Kazuhiko Kamikado, Takuya Kanazawa
We investigate the quark-meson model in a magnetic field using the exact functional renormalization group equation beyond the local-potential approximation. Our truncation of the e…
Real-Time Correlation Functions in the O(N) Model from the Functional Renormalization Group
Kazuhiko Kamikado, Nils Strodthoff, Lorenz von Smekal +1
In the framework of the functional renormalization group (FRG) we present a simple truncation scheme for the computation of real-time mesonic n-point functions, consistent with the…
Functional Renormalization Group Study of Phonon Mode Effects on Chiral Critical Point
K. Kamikado, T. Kunihiro, K. Morita +1
We apply the functional renormalization-group (FRG) equation to analyze the nature of the QCD critical point beyond the mean-field approximation by taking into consideration the fa…
Fluctuations in the quark-meson model for QCD with isospin chemical potential
Kazuhiko Kamikado, Nils Strodthoff, Lorenz von Smekal +1
We study the two-flavor quark-meson (QM) model with the functional renormalization group (FRG) to describe the effects of collective mesonic fluctuations on the phase diagram of QC…
Second-order and Fluctuation-induced First-order Phase Transitions with Functional Renormalization Group Equations
Kenji Fukushima, Kazuhiko Kamikado, Bertram Klein
We investigate phase transitions in scalar field theories using the functional renormalization group (RG) equation. We analyze a system with symmetry, in which th…
