Thermal-induced Local Imbalance in Repulsive Binary Bose Mixtures
Gerard Pascual, Gabriele Spada, Sebastiano Pilati +2
We study repulsive two-component Bose mixtures with equal populations and confined in a finite-size box through path-integral Monte Carlo simulations. For different values of the $…
Symmetry-broken perturbation theory to large orders in antiferromagnetic phases
R. Garioud, F. Šimkovic, R. Rossi +4
We introduce a spin-symmetry-broken extension of the connected determinant algorithm [Phys. Rev. Lett. 119, 045701 (2017)]. The resulting systematic perturbative expansions around…
Thermodynamics of a dilute Bose gas: A path-integral Monte Carlo study
Gabriele Spada, Sebastiano Pilati, Stefano Giorgini
We present precise path-integral Monte-Carlo results for the thermodynamics of a homogeneous dilute Bose gas. Pressure and energy are calculated as a function of temperature both b…
High-order expansion around BCS theory
G. Spada, R. Rossi, F. Simkovic +4
We demonstrate that summation of connected diagrams to high order starting from a BCS hamiltonian is a viable generic unbiased approach for strongly correlated fermions in supercon…
Self-Dualities and Renormalization Dependence of the Phase Diagram in 3d Vector Models
Giacomo Sberveglieri, Marco Serone, Gabriele Spada
In the classically unbroken phase, 3d symmetric vector models admit two equivalent descriptions connected by a strong-weak duality closely related to the one found by…
Renormalization Scheme Dependence, RG Flow and Borel Summability in Theories in
Giacomo Sberveglieri, Marco Serone, Gabriele Spada
Renormalization group (RG) and resummation techniques have been used in -component theories at fixed dimensions below four to determine the presence of non-trivial IR fixe…
