On the commuting charges and the Bethe ansatz for the quantised Kadomtsev-Petviashvili equation
Chiara Paletta, Alessandro Torrielli
We study the quantised version of the Kadomtsev-Petviashvili equation in the formulation proposed in [4]. We analyse two aspects. One is the conservation of the first higher charge…
Open-boundary integrable quantum circuits with different geometries
Miguel García Fernández, Chiara Paletta, Ana L. Retore
We present a complete classification of integrable Yang-Baxter quantum circuits with open boundary conditions and arbitrary circuit geometries. Starting from the standard transfer-…
On the integrability structure of the deformed rule-54 reversible cellular automaton
Chiara Paletta, Tomaž Prosen
We study quantum and stochastic deformations of the rule-54 reversible cellular automaton (RCA54) on a 1+1-dimensional spatiotemporal lattice, focusing on their integrability struc…
Integrability and charge transport in asymmetric quantum-circuit geometries
Chiara Paletta, Urban Duh, Balázs Pozsgay +1
We revisit the integrability of quantum circuits constructed from two-qubit unitary gates that satisfy the Yang-Baxter equation. A brickwork arrangement of typically corres…
Weak ergodicity breaking with isolated integrable sectors
Hosho Katsura, Chihiro Matsui, Chiara Paletta +1
We consider spin chain models with local Hamiltonians that display weak ergodicity breaking. In these models, the majority of the eigenstates are thermal, but there is a distinguis…
Integrability of open boundary driven quantum circuits
Chiara Paletta, Tomaž Prosen
In this paper, we address the problem of Yang-Baxter integrability of doubled quantum circuit of qubits (spins 1/2) with open boundary conditions where the two circuit replicas are…
Yang-Baxter integrable open quantum systems
Chiara Paletta
This work is based on the author's PhD thesis. The main result of the thesis is the use of the boost operator to develop a systematic method to construct new integrable spin chains…
Hidden quasi-local charges and Gibbs ensemble in a Lindblad system
Marius de Leeuw, Chiara Paletta, Balázs Pozsgay +1
We consider spin-1/2 chains with external driving that breaks the continuous symmetries of the Hamiltonian. We introduce a family of models described by the Lindblad equation with…
A range three elliptic deformation of the Hubbard model
Marius de Leeuw, Chiara Paletta, Balázs Pozsgay
In this paper we present a new integrable deformation of the Hubbard model. Our deformation gives rise to a range 3 interaction term in the Hamiltonian which does not preserve spin…
The Bethe ansatz for a new integrable open quantum system
Marius de Leeuw, Chiara Paletta
In this paper we apply the nested algebraic Bethe ansatz to compute the eigenvalues and the Bethe equations of the transfer matrix of the new integrable Lindbladian found in [1]. W…
Constructing Integrable Lindblad Superoperators
Marius de Leeuw, Chiara Paletta, Balázs Pozsgay
We develop a new method for the construction of one-dimensional integrable Lindblad systems, which describe quantum many body models in contact with a Markovian environment. We fin…
Yang-Baxter and the Boost: splitting the difference
Marius de Leeuw, Chiara Paletta, Anton Pribytok +2
In this paper we continue our classification of regular solutions of the Yang-Baxter equation using the method based on the spin chain boost operator developed in \cite{deLeeuw:201…
Free Fermions, vertex Hamiltonians, and lower-dimensional AdS/CFT
Marius de Leeuw, Chiara Paletta, Anton Pribytok +2
In this paper we first demonstrate explicitly that the new models of integrable nearest-neighbour Hamiltonians recently introduced in PRL 125 (2020) 031604 satisfy the so-called fr…
Classifying nearest-neighbour interactions and deformations of AdS
Marius de Leeuw, Chiara Paletta, Anton Pribytok +2
We classify all regular solutions of the Yang-Baxter equation of eight-vertex type. Regular solutions correspond to spin chains with nearest-neighbour interactions. We find a total…
