Three-body loss in lithium from functional renormalization
R. Schmidt, S. Floerchinger, C. Wetterich
We use functional integral methods for an estimate of the three-body loss in a three-component Li ultracold atom gas. We advocate a simple picture where the loss proceeds by th…
Efimov effect from functional renormalization
S. Moroz, S. Floerchinger, R. Schmidt +1
We apply a field-theoretic functional renormalization group technique to the few-body (vacuum) physics of non-relativistic atoms near a Feshbach resonance. Three systems are consid…
Functional renormalization for trion formation in ultracold fermion gases
S. Floerchinger, R. Schmidt, S. Moroz +1
The energy spectrum for three species of identical fermionic atoms close to a Feshbach resonance is computed by use of a nonperturbative flow equation. Already a simple truncation…
Particle-hole fluctuations in the BCS-BEC Crossover
S. Floerchinger, M. Scherer, S. Diehl +1
The effect of particle-hole fluctuations for the BCS-BEC crossover is investigated by use of functional renormalization. We compute the critical temperature for the whole range in…
Superfluid Bose gas in two dimensions
S. Floerchinger, C. Wetterich
We investigate Bose-Einstein condensation for ultracold bosonic atoms in two-dimensional systems. The functional renormalization group for the average action allows us to follow th…
Functional renormalization for Bose-Einstein Condensation
S. Floerchinger, C. Wetterich
We investigate Bose-Einstein condensation for interacting bosons at zero and nonzero temperature. Functional renormalization provides us with a consistent method to compute the eff…
