The boundary-driven multispecies harmonic process
Francesco Casini, Rouven Frassek, Cristian GiardinÃ
The paper introduces a multispecies harmonic process on a one‑dimensional lattice with boundary reservoirs, linking its Markov generator to an integrable open rational Heisenberg s…
Intertwining Markov Processes via Matrix Product Operators
Rouven Frassek, Jan de Gier, Jimin Li +1
Duality transformations reveal unexpected equivalences between seemingly distinct models. We introduce an out-of-equilibrium generalisation of matrix product operators to implement…
Steady state representations for the harmonic process
Rouven Frassek
In this note we discuss how the matrix product solution for the steady state of the harmonic process is obtained from the solutions already known in the literature, i.e. the closed…
On the Quantum Spectral Curve for strings and the Q-system
Andrea CavagliÃ, Rouven Frassek, Nicolò Primi +1
In this paper, we put forward and discuss a proposal for a Quantum Spectral Curve (QSC) describing the planar spectrum of the holographic CFT dual to strings on AdS S$^3\…
Orthosymplectic Yangians
Rouven Frassek, Alexander Tsymbaliuk
We study the RTT orthosymplectic super Yangians and present their Drinfeld realizations for any parity sequence, generalizing the results for non-super types BCD, a standard parity…
