Exact dimer ground states of long-range spin chains and ladders
Jędrzej Wardyn, Miłosz Panfil
Interacting spin chains and ladders are known to support a plethora of quantum phases with complex ground-state phase diagrams. In this work, we study a large family of such models…
Crossover from generalized to conventional hydrodynamics in nearly integrable systems under relaxation time approximation
Saikat Santra, Maciej Łebek, Miłosz Panfil
Upon breaking the integrability, the equations of generalized hydrodynamics (GHD) are supplemented by a Boltzmann collision term. Such terms are typically complicated and stem from…
Burgers equation from non-thermal stationary states in nearly-integrable gases
Paweł Lisiak, Maciej Łebek, Miłosz Panfil
When a gas of particles interacts with much a larger reservoir the density dynamics on large scales is typically governed by diffusion. We study this paradigmatic problem for weakl…

Stanisław Kiedrzyński, Emilia Witkowska, Miłosz Panfil
We study the quantum hard-rods model and obtain compact analytical expressions for density form factors, and a semi-analytical treatment for dynamic and static structure factors ca…
Chapman-Enskog theory and crossover between diffusion and superdiffusion for nearly integrable quantum gases
Maciej Łebek, Miłosz Panfil
Integrable systems feature an infinite number of conserved charges and on hydrodynamic scales are described by generalised hydrodynamics (GHD). This description breaks down when th…

We study the rapidity distribution in the Lieb-Liniger model and derive exact relations for its derivatives at the Fermi level. The latter enables us to treat analytically the free…
Quantum features of the transport through ion channels in the soft knock-on model
Mateusz Polakowski, Miłosz Panfil
Ion channels are protein structures that facilitate the selective passage of ions across the membrane cells of living organisms. They are known for their high conductance and high…
Generalised BBGKY hierarchy for near-integrable dynamics
Leonardo Biagetti, Maciej Lebek, Milosz Panfil +1
We study quantum and classical many-body Hamiltonian systems that combine integrable contact interactions with generic long-range two-body potentials. Starting from an ansatz for t…

The Navier-Stokes equations are paradigmatic equations describing hydrodynamics of an interacting system with microscopic interactions encoded in transport coefficients. In this wo…
Long-living prethermalization in nearly integrable spin ladders
J. Pawlowski, M. Panfil, J. Herbrych +1
Relaxation rates in nearly integrable systems usually increase quadratically with the strength of the perturbation that breaks integrability. We show that the relaxation rates can…

In this work we study the Kubo-Martin-Schwinger (KMS) relation in the Yang-Gaudin model of an interacting mobile impurity. We use the integrability of the model to compute the dyna…
