Orthogonal Polynomial Duality and Unitary Symmetries of Multi-species ASEP (q, θ) and Higher-Spin Vertex Models via∗-Bialgebra Structure of Higher Rank …

C Franceschini, J Kuan, Z Zhou - Communications in Mathematical …, 2024 - Springer
We propose a general method to produce orthogonal polynomial dualities from the∗-
bialgebra structure of Drinfeld–Jimbo quantum groups. The∗-structure allows for the …

Integrable heat conduction model

C Franceschini, R Frassek, C Giardinà - Journal of Mathematical …, 2023 - pubs.aip.org
We consider a stochastic process of heat conduction where energy is redistributed along a
chain between nearest neighbor sites via an improper beta distribution. Similar to the well …

Non-compact quantum spin chains as integrable stochastic particle processes

R Frassek, C Giardinà, J Kurchan - Journal of Statistical Physics, 2020 - Springer
In this paper we discuss a family of models of particle and energy diffusion on a one-
dimensional lattice, related to those studied previously in Sasamoto and Wadati (Phys Rev E …

Orthogonal dualities of Markov processes and unitary symmetries

G Carinci, C Franceschini, C Giardinà… - … and Geometry: Methods …, 2019 - emis.de
We study self-duality for interacting particle systems, where the particles move as continuous
time random walkers having either exclusion interaction or inclusion interaction. We show …

Stochastic duality and orthogonal polynomials

C Franceschini, C Giardina - Sojourns in Probability Theory and Statistical …, 2019 - Springer
For a series of Markov processes we prove stochastic duality relations with duality functions
given by orthogonal polynomials. This means that expectations with respect to the original …

Approximate filtering via discrete dual processes

GKK King, A Pandolfi, M Piretto, M Ruggiero - Stochastic Processes and …, 2024 - Elsevier
We consider the task of filtering a dynamic parameter evolving as a diffusion process, given
data collected at discrete times from a likelihood which is conjugate to the reversible law of …

Orthogonal polynomial duality of a two-species asymmetric exclusion process

D Blyschak, O Burke, J Kuan, D Li, S Ustilovsky… - Journal of Statistical …, 2023 - Springer
We examine type D ASEP, a two-species interacting particle system which generalizes the
usual asymmetric simple exclusion process. For certain cases of type D ASEP, the process …

Two Dualities: Markov and Schur–Weyl

J Kuan - International Mathematics Research Notices, 2022 - academic.oup.com
We show that quantum Schur–Weyl duality leads to Markov duality for a variety of
asymmetric interacting particle systems. In particular, we consider the following three …

Similarity revisited: shock random walks in the asymmetric simple exclusion process with open boundaries

GM Schütz - The European Physical Journal Special Topics, 2023 - Springer
A reverse duality between the asymmetric simple exclusion process (ASEP) with open
boundary conditions and a biased random walk of a single particle is proved for a special …

Orthogonal dualities for asymmetric particle systems

G Carinci, C Franceschini… - Electronic Journal of …, 2021 - projecteuclid.org
We study a class of interacting particle systems with asymmetric interaction showing a self-
duality property. The class includes the ASEP (q, θ), asymmetric exclusion process, with a …
