Hall effect in multi-leg bosonic ladders
Edmond Orignac, Roberta Citro, Thierry Giamarchi
We use bosonization to analyze the ground state Hall response of interacting bosonic N-leg ladders threaded by a flux. We derive an explicit expression of the Hall imbalance in a p…
Mapping reservoir-enhanced superconductivity to near-long-range magnetic order in the undoped one-dimensional Anderson and Kondo lattices
J. E. Ebot, Lorenzo Pizzino, Sam Mardazad +3
The undoped Kondo necklace in 1D is a paradigmatic and well understood model of a Kondo insulator. This work performs the first large-scale study of the 1D Anderson-lattice underly…
Enhancement of superconducting stiffness in hybrid superconducting-metallic bilayers
J. E. Ebot, Lorenzo Pizzino, Sam Mardazad +3
Boosting superconductivity by metallic reservoirs is the essence of Kivelson's bilayer proposal. One layer provides pairing to the electrons, while the weakly coupled metal provide…
Mobile Impurity in a Two-Leg Bosonic Ladder
Naushad Ahmad Kamar, Adrian Kantian, Thierry Giamarchi
We study the dynamics of a mobile impurity in a two-leg bosonic ladder. The impurity moves both along and across the legs and interacts with a bath of interacting bosonic particles…
Platforms for the realization and characterization of Tomonaga-Luttinger liquids
Isabelle Bouchoule, Roberta Citro, Tim Duty +5
The concept of a Tomonaga-Luttinger liquid (TLL) has been established as a fundamental theory for the understanding of one-dimensional quantum systems. Originally formulated as a r…
