Derivations for the MPS overlap formulas of rational spin chains
Tamas Gombor
We derive a universal formula for the overlaps between integrable matrix product states (MPS) and Bethe eigenstates in symmetric spin chains. This formula expre…
Exact overlaps for "all" integrable matrix product states of rational spin chains
Tamas Gombor
The overlaps between integrable matrix product states (MPS) and Bethe states are important in both the non-equilibrium statistical physics and the AdS/CFT duality. We present the g…
On exact overlaps of integrable matrix product states: inhomogeneities, twists and dressing formulas
Tamas Gombor, Charlotte Kristjansen, Vasileios Moustakis +1
Invoking a quantum dressing procedure as well as the representation theory of twisted Yangians we derive a number of summation formulas for the overlap between integrable matrix pr…
Dual overlaps and finite coupling 't Hooft loops
Tamas Gombor, Zoltán Bajnok
Integrable symmetric models have integrable boundaries with symmetries, which can be embedded into in two different ways. We dual…
Exact overlaps for all integrable two-site boundary states of symmetric spin chains
Tamas Gombor
We find closed formulas for the overlaps of Bethe eigenstates of symmetric spin chains and integrable boundary states. We derive the general overlap formulas for…
Integrable crosscaps in classical sigma models
Tamas Gombor
We study the integrable boundaries and crosscaps of classical sigma models. We show that there exists a classical analog of the integrability condition and KT-relation of the bound…
Overlaps for Matrix Product States of Arbitrary Bond Dimension in ABJM theory
Tamas Gombor, Charlotte Kristjansen
We find a closed formula for the overlap of Bethe eigenstates of an alternating spin chain, describing the scalar sector of ABJM theory, and matrix product states of any bo…
Integrable crosscap states in spin chains
Tamas Gombor
We study the integrable crosscap states of the integrable quantum spin chains and we classify them for the symmetric models. We also give a derivation for the ex…
Wrapping corrections for long range spin chains
Tamas Gombor
The long range spin chains play an important role in the gauge/string duality. The aim of this paper is to generalize the recently introduced transfer matrices of integrable medium…
Integrable deformations of superintegrable quantum circuits
Tamás Gombor, Balázs Pozsgay
Superintegrable models are very special dynamical systems: they possess more conservation laws than what is necessary for complete integrability. This severely constrains their dyn…
Superintegrable cellular automata and dual unitary gates from Yang-Baxter maps
Tamás Gombor, Balázs Pozsgay
We consider one dimensional block cellular automata, where the local update rules are given by Yang-Baxter maps, which are set theoretical solutions of the Yang-Baxter equations. W…
Integrable hard rod deformation of the Heisenberg spin chains
Balázs Pozsgay, Tamás Gombor, Arthur Hutsalyuk
We present new integrable models of interacting spin-1/2 chains, which can be interpreted as hard rod deformations of the XXZ Heisenberg chains. The models support multiple particl…
Integrable spin chains and cellular automata with medium range interaction
Tamás Gombor, Balázs Pozsgay
We study integrable spin chains and quantum and classical cellular automata with interaction range . This is a family of integrable models for which there was no general…
An integrable spin chain with Hilbert space fragmentation and solvable real time dynamics
Balázs Pozsgay, Tamás Gombor, Arthur Hutsalyuk +3
We revisit the so-called folded XXZ model, which was treated earlier by two independent research groups. We argue that this spin-1/2 chain is one of the simplest quantum integrable…
On factorized overlaps: Algebraic Bethe Ansatz, twists, and Separation of Variables
Tamás Gombor, Balázs Pozsgay
We investigate the exact overlaps between eigenstates of integrable spin chains and a special class of states called "integrable initial/final states". These states satisfy a speci…
Boundary state bootstrap and asymptotic overlaps in AdS/dCFT
Tamas Gombor, Zoltan Bajnok
We formulate and close the boundary state bootstrap for factorizing K-matrices in AdS/CFT. We found that there are no boundary degrees of freedom in the boundary bound states, mere…
Boundary states, overlaps, nesting and bootstrapping AdS/dCFT
Tamas Gombor, Zoltan Bajnok
Integrable boundary states can be built up from pair annihilation amplitudes called -matrices. These amplitudes are related to mirror reflections and they both satisfy Yang Baxt…
Spin Chain Overlaps and the Twisted Yangian
Marius de Leeuw, Tamás Gombor, Charlotte Kristjansen +2
Using considerations based on the thermodynamical Bethe ansatz as well representation theory of twisted Yangians we derive an exact expression for the overlaps between the Bethe ei…
On the classification of rational K-matrices
Tamas Gombor
This paper presents a derivation of the possible residual symmetries of rational K-matrices which are invertible in the ''classical limit'' (the spectral parameter goes to infinity…
Nonstandard Bethe Ansatz equations for open O(N) spin chains
Tamas Gombor
The double row transfer matrix of the open O(N) spin chain is diagonalized and the Bethe Ansatz equations are also derived by the algebraic Bethe Ansatz method including the so far…
On integrable boundaries in the 2 dimensional -models
Ines Aniceto, Zoltan Bajnok, Tamas Gombor +2
We make an attempt to map the integrable boundary conditions for 2 dimensional non-linear O(N) -models. We do it at various levels: classically, by demanding the existence of in…
Algebraic Bethe Ansatz for O(2N) sigma models with integrable diagonal boundaries
Tamas Gombor, Laszlo Palla
The finite volume problem of O(2N) sigma models with integrable diagonal boundaries on a finite interval is investigated. The double row transfer matrix is diagonalized by Algebrai…
