Resonantly enhanced superconductivity mediated by spinor condensates
Giacomo Bighin, Puneet A. Murthy, Nicolò Defenu +1
Achieving strong interactions in fermionic many-body systems is a major theme of research in condensed matter physics. It is well-known that interactions between fermions can be me…
Universal scaling in real dimension
Giacomo Bighin, Tilman Enss, Nicolò Defenu
The concept of universality has shaped our understanding of many-body physics, but is mostly limited to homogenous systems. Here, we present a study of universality on a non-homoge…
Unitary Fermi superfluid near the critical temperature: thermodynamics and sound modes from elementary excitations
G. Bighin, A. Cappellaro, L. Salasnich
We compare recent experimental results [Science 375, 528 (2022)] of the superfluid unitary Fermi gas near the critical temperature with a thermodynamic model based on elementary ex…
Diagrammatic Monte Carlo for electronic correlation in molecules: high-order many-body perturbation theory with low scaling
G. Bighin, Q. P. Ho, M. Lemeshko +1
We present a low-scaling diagrammatic Monte Carlo approach to molecular correlation energies. Using combinatorial graph theory to encode many-body Hugenholtz diagrams, we sample th…
A simple model for high rotational excitations of molecules in a superfluid
Igor N. Cherepanov, Giacomo Bighin, Constant A. Schouder +3
We present a simple quantum mechanical model describing excited rotational states of molecules in superfluid helium nanodroplets, as recently studied in non-adiabatic molecular ali…
