Periodic orbits and quantum many-body scars in integrable spin chains
Elena Petrova, Maksym Serbyn, Marko Ljubotina
Quantum many-body scars provide an exception to generic thermalising dynamics, but their relation to integrability remains unclear. Here we apply the periodic-orbit framework to th…
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…
Discrete solitons in Rydberg atom chains
Aron Kerschbaumer, Jean-Yves Desaules, Marko Ljubotina +1
Solitons - localized wave packets that travel without spreading - play a central role in understanding transport and properties of nonlinear systems, from optical fibers to fluid d…
Learning mixed quantum states in large-scale experiments
Matteo Votto, Marko Ljubotina, Cécilia Lancien +5
We present and test a protocol to learn the matrix-product operator (MPO) representation of an experimentally prepared quantum state. The protocol takes as an input classical shado…
Finding periodic orbits in projected quantum many-body dynamics
Elena Petrova, Marko Ljubotina, Gökhan Yalnız +1
Describing general quantum many-body dynamics is a challenging task due to the exponential growth of the Hilbert space with system size. The time-dependent variational principle (T…
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.…
