Attraction from frustration in ladder systems
Ivan Morera, Annabelle Bohrdt, Wen Wei Ho +1
We analyze the formation of multi-particle bound states in ladders with frustrated kinetic energy in two component bosonic and two component fermionic systems. We focus on the regi…
Renormalization group study of Bose polarons
Felipe Isaule, Ivan Morera, Pietro Massignan +1
We study the properties of a single impurity in a dilute Bose gas, a Bose polaron, using the functional renormalization group. We use an ansatz for the effective action motivated b…
Quantum liquids and droplets with low-energy interactions in one dimension
Ivan Morera, Bruno Juliá-Díaz, Manuel Valiente
We consider interacting one-dimensional bosons in the universal low-energy regime. The interactions consist of a combination of attractive and repulsive parts that can stabilize qu…
