Magnetic Couplings in Half-Filled Bipartite Graphs
Georges Bouzerar
We break from perturbative frameworks to establish a non-perturbative generalization of magnetic exchange rules in half-filled bipartite networks. While historical models remain st…
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…
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…
Strengthening of the superconductivity by real space decimation of the flat band states
M. Thumin, G. Bouzerar
In contrast to standard BCS superconductivity, that in flat bands (FBs) possesses an interesting degree of freedom that enables the control of the superfluid weight (SFW), referred…
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…
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…
Constrain relations for superfluid weight and pairings in a chiral flat band superconductor
M. Thumin, G. Bouzerar
Within ten years, flat band (FB) superconductivity has gained a huge interest for its remarkable features and connection to quantum geometry. We investigate the superconductivity i…
Hidden symmetry of Bogoliubov de Gennes quasi-particle eigenstates and universal relations in flat band superconducting bipartite lattices
G. Bouzerar, M. Thumin
Unconventional flat band (FB) superconductivity, as observed in van der Waals heterostructures, could open promising avenues towards high-T materials. In FBs, pairings and supe…
Flat band superconductivity in a system with a tunable quantum metric : the stub lattice
Maxime Thumin, Georges Bouzerar
Over the past years, one witnesses a growing interest in flat band (FB) physics which has become a playground for exotic phenomena. In this study, we address the FB superconductivi…
Dynamics of Excited Electrons in Copper: Role of Auger Electrons
R. Knorren, G. Bouzerar, K. H. Bennemann
Within a theoretical model based on the Boltzmann equation, we analyze in detail the structure of the unusual peak recently observed in the relaxation time in Cu. In particular, we…
