BCS-BEC crossover and superconductor-insulator transition in Hopf-linked Graphene layers: Hopfene

Materials Research Express, 2019
We have proposed a topological carbon allotrope, named Hopfene, which has three-dimensional (3 D ) arrays of Hopf-links to bind 2 D Graphene layers both horizontally and vertically without forming strong σ bonds between layers. Tight-binding calculations

Functional renormalization for the BCS-BEC crossover

, 2010
We review the functional renormalization group (RG) approach to the BCS-BEC crossover for an ultracold gas of fermionic atoms. Formulated in terms of a scale-dependent effective action, the functional RG interpolates continuously between the atomic or molecular microphysics and the macroscopic physics on large length scales.

Collective mode across the BCS-BEC crossover in Holstein model

Physical Review Research
We investigate the emergence of the collective mode in the phonon spectra of the superconducting state within the Holstein model by varying the electron-phonon coupling.

Neural-network quantum states for ultra-cold Fermi gases

Communications Physics
Ultra-cold Fermi gases exhibit a rich array of quantum mechanical properties, including the transition from a fermionic superfluid Bardeen-Cooper-Schrieffer (BCS) state to a bosonic superfluid Bose-Einstein condensate (BEC). While these properties can be

BCS-BEC Crossover and the Unitary Fermi Gas

, 2013
The crossover from weak coupling Bardeen-Cooper-Schrieffer (BCS) pairing to a Bose-Einstein condensate (BEC) of tightly bound pairs, as a function of the attractive interaction in Fermi systems, has long been of interest to theoretical physicists. The past decade has seen a series of remarkable experimental developments in ultracold Fermi gases that ...
