Optimal Disorder Strength for Approximate Unitary -Designs in Spin Chains
Tian-Gang Zhou, Yi-Neng Zhou, Thierry Giamarchi +1
Quantum simulators with disordered spin Hamiltonians offer a natural route to Haar-like unitary ensembles, but face a competition. Disorder enhances randomness, yet strong disorder…
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…
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…
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…
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…
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…
Quantum dynamics of impurities in a 1D Bose gas
J. Catani, G. Lamporesi, D. Naik +5
Using a species-selective dipole potential, we create initially localized impurities and investigate their interactions with a majority species of bosonic atoms in a one-dimensiona…
Coupled Ladders in a Magnetic Field
T. Giamarchi, A. M. Tsvelik
We investigate the phase transitions in two-leg ladders systems in the incommensurate phase, for which the gap is destroyed by a magnetic field () and the ladder is not…
Effects of a weak disorder on two coupled Hubbard chains
E. Orignac, T. Giamarchi
We consider the effect of weak nonmagnetic disorder on two chains of interacting fermions (with and without spins) coupled by interchain hopping. For the spinless case, interchain…
Does the attractive Hubbard model support larger persistent currents than the repulsive one ?
T. Giamarchi, B. S. Shastry
We consider a one-dimensional Hubbard model in the presence of disorder. We compute the charge stiffness for a mesoscopic ring, as a function of the size , which is a measure of…
