parafermion in the double charge-Kondo model
D. B. Karki, Edouard Boulat, Winston Pouse +3
Quantum impurity models with frustrated Kondo interactions can support quantum critical points with fractionalized excitations. Recent experiments [arXiv:2108.12691] on a circuit c…
Two-sites quantum island in the quasi-ballistic regime
Deepak B. Karki, Edouard Boulat, Christophe Mora
Quantum Hall edge channels can be combined with metallic regions to fractionalize electrons and form correlated impurity models. We study a minimal device, that has been experiment…
Universality at work -- the local sine-Gordon model, lattice fermions, and quantum circuits
A. Anthore, D. M. Kennes, E. Boulat +3
We review the intriguing many-body physics resulting out of the interplay of a single, local impurity and the two-particle interaction in a one-dimensional Fermi system. Even if th…
Full exact solution of the out-of-equilibrium boundary sine Gordon model
Edouard Boulat
The massless boundary sine-Gordon (SG) model is the only interacting impurity model with a known exact solution out-of-equilibrium, yet existing so far only for integer values of t…
Circuit Quantum Simulation of a Tomonaga-Luttinger Liquid with an Impurity
A. Anthore, Z. Iftikhar, E. Boulat +5
The Tomonaga-Luttinger liquid (TLL) concept is believed to generically describe the strongly-correlated physics of one-dimensional systems at low temperatures. A hallmark signature…
Out-of-equilibrium properties and non-linear effects for interacting quantum impurity systems in their strong coupling regime
Loïc Freton, Edouard Boulat
We provide an exact description of out-of-equilibrium fixed points in quantum impurity systems, that is able to treat time-dependent forcing. Building on this, we then show that an…
