Phase diagram of two-component mean-field Bose mixtures
Oskar Stachowiak, Pawel Jakubczyk
We revisit the structure of the phase diagram of the two-component mean-field Bose mixture at finite temperatures, considering both the cases of attractive and repulsive interspeci…
Anisotropic scale invariance and the uniaxial Lifshitz point from the nonperturbative renormalization group
Gonzalo De Polsi, Pawel Jakubczyk
We employ the derivative expansion of the nonperturbative renormalization group to address the phenomenon of anisotropic scale invariance and the associated functional fixed points…
Thermal Casimir effect in the spin-orbit coupled Bose gas
Marek Napiórkowski, Pawel Jakubczyk
We study the thermal Casimir effect in ideal Bose gases with spin-orbit (S-O) coupling of Rashba type below the critical temperature for Bose-Einstein condensation. In contrast to…
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, PaweÅ 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…
Spin-orbit coupled mean-field Bose gas at finite temperature
Pawel Jakubczyk, Marek Napiórkowski
We consider the spin-orbit coupled Bose gas with repulsive mean-field interparticle interactions. We analyze the phase diagram of the system varying the temperature , the chem…
