Periodic orbits and quantum many-body scars in integrable spin chains
Elena Petrova, Maksym Serbyn, Marko Ljubotina
The paper applies periodic‑orbit theory to integrable XYZ/XXZ spin‑1/2 chains, identifying families of scarred periodic orbits and reconstructing the associated non‑thermal eigenst…
Coherent dynamics in chaotic spin chains via interference-protected subspaces
Aron Kerschbaumer, Jean-Yves Desaules, Maksym Serbyn
Generic quantum many-body systems are expected to thermalize, scrambling initial coherence while local observables relax to equilibrium values. Weak ergodicity breaking, often asso…
Tensor Cross Interpolation of Purities in Quantum Many-Body Systems
Dmytro Kolisnyk, Raimel A. Medina, Romain Vasseur +1
A defining feature of quantum many-body systems is the exponential scaling of the Hilbert space with the number of degrees of freedom. This exponential complexity naïvely renders…
Systematic construction of quantum many-body scars in frustrated Rydberg arrays
Jean-Yves Desaules, Aron Kerschbaumer, Marko Ljubotina +1
Quantum many-body scars in Rydberg atom arrays have thus far only been observed on bipartite lattices, leaving open the question of whether and how they survive frustration, and wh…
Plasmon decay and non-equilibrium steady states in Josephson junction chains
Lucia Vigliotti, Andrew P. Higginbotham, Maksym Serbyn
Josephson junction (JJ) chains combine the coherence of superconductivity with the controllability of microwave-frequency circuits, making them a powerful platform for circuit quan…
Fragmentation, Zero Modes, and Collective Bound States in Constrained Models
Eloi Nicolau, Marko Ljubotina, Maksym Serbyn
Kinetically constrained models were originally introduced to capture slow relaxation in glassy systems, where dynamics are hindered by local constraints instead of energy barriers.…
