Kardar-Parisi-Zhang superdiffusion in chaotic quantum circuits
Rustem Sharipov, Urban Duh, Sun Woo P. Kim +1
We construct a family of chaotic brickwork quantum circuits exhibiting superdiffusive transport with dynamical exponent in the full Kardar--Parisi--Zhang (KPZ) universality…
Solvable relaxation in discrete unitary systems: Ruelle-Pollicott resonances and CMV matrices
Urban Duh, Friedrich Hübner, Marko Žnidarič
Leading eigenvalues of the truncated propagator, known as Ruelle-Pollicott (RP) resonances, are an elegant way of addressing the dynamics of unitary many-body systems. We study uni…
Interacting Quantum Symmetric Exclusion Process
Denis Bernard, Friedrich Hübner, Stefano Scopa
We introduce and solve the Interacting Quantum Symmetric Exclusion Process (IQSEP), a family of models describing the stochastic quantum hopping of charged particles along the edge…
Hydrodynamics without Averaging -- a Hard Rods Study
Friedrich Hübner
On the example of the integrable hard rods model we study the quality of the (generalized) hydrodynamic approximation on a single coarse-grained sample. This is opposed to the trad…
Circuits as a simple platform for the emergence of hydrodynamics in deterministic chaotic many-body systems
Sun Woo P. Kim, Friedrich Hübner, Juan P. Garrahan +1
The emergence of hydrodynamics is one of the deepest phenomena in many-body systems. Arguably, the hydrodynamic equations are also the most important tools for predicting large-sca…
Diffusive hydrodynamics from long-range correlations
Friedrich Hübner, Leonardo Biagetti, Jacopo De Nardis +1
In the hydrodynamic theory, the non-equilibrium dynamics of a many-body system is approximated, at large scales of space and time, by irreversible relaxation to local entropy maxim…
Generalized hydrodynamics of integrable quantum circuits
Friedrich Hübner, Eric Vernier, Lorenzo Piroli
Quantum circuits make it possible to simulate the continuous-time dynamics of a many-body Hamiltonian by implementing discrete Trotter steps of duration . However, when is s…
New classical integrable systems from generalized -deformations
Benjamin Doyon, Friedrich Hübner, Takato Yoshimura
We introduce and study a novel class of classical integrable many-body systems obtained by generalized -deformations of free particles. Deformation terms are bilinears in…
Towards an ab initio derivation of generalised hydrodynamics from a gas of interacting wave packets
Benjamin Doyon, Friedrich Hübner
We present steps towards an ab initio derivation of generalised hydrodynamics in quantum integrable models, starting from the Bethe wave functions, and explained on the example of…
Mesoscopic Impurities in Generalized Hydrodynamics
Friedrich Hübner
We study impurities in integrable models from the viewpoint of generalized hydrodynamics (GHD). An impurity can be thought of as a boundary condition for the GHD equation, relating…
Momentum resolved Floquet-engineered pair and single particle filter in the Fermi Hubbard model
Friedrich Hübner, Christoph Dauer, Sebastian Eggert +2
We investigate the transport properties of a Fermi-Hubbard chain with an impurity which is formed by a site with a periodically modulated chemical potential. We determine the momen…
Suppression of scattering from slow to fast subsystems and application to resonantly Floquet-driven impurities in strongly interacting systems
Friedrich Hübner
We study solutions to the Lippmann-Schwinger equation in systems where a slow subsystem is coupled to a fast subsystem via an impurity. Such situations appear when a high-frequency…
Floquet-engineered pair and single particle filter in the Fermi Hubbard model
Friedrich Hübner, Christoph Dauer, Sebastian Eggert +2
We investigate the Fermi-Hubbard model with a Floquet-driven impurity in the form of a local time-oscillating potential. For strong attractive interactions a stable formation of pa…
