Flux-induced strengthening of the magnetic couplings in a flat-band diamond chain
Biplab Pal, Maxime Thumin, Georges Bouzerar
The physics in flat bands has emerged as an essential field in condensed matter physics where a plethora of phenomena can be unveiled, such as anomalous transport properties, super…
Robustness of flat band superconductivity against disorder in a two-dimensional Lieb lattice model
Georges Bouzerar, Maxime Thumin
Recently, the possibility of high-temperature superconductivity (SC) in flat-band (FB) systems has been the focus of a great deal of activity. This study reveals that unlike conven…
Crossing over from flat band superconductivity to conventional superconductivity
M. Thumin, G. Bouzerar
Over the past ten years, flat band (FB) or geometric superconductivity has become a major issue in condensed matter physics due to the significant technological benefits it could o…
Engineering flux-controlled flat bands and topological states in a Stagome lattice
Biplab Pal, Georges Bouzerar
We present the Stagome lattice, a variant of the Kagome lattice, where one can make any of the bands completely flat by tuning an externally controllable magnetic flux. This system…
Generating long-distance magnetic couplings with flat bands
Georges Bouzerar, Maxime Thumin
One of the great challenges for the large-scale development of quantum technologies is to generate and control the entanglement of quantum bits through interactions of sufficiently…
Correlation functions and characteristic lengthscales in flat band superconductors
Maxime Thumin, Georges Bouzerar
The possibility of an unconventional form of high temperature superconductivity in flat band (FB) material does not cease to challenge our understanding of the physics in correlate…
