Geodesic steering for rapid dissipative entanglement distribution
Keshav Venkataraman, Pablo Martinez-Azcona, Marko Ljubotina +2
We describe an optimal-control strategy designed to accelerate the dissipative preparation of complex, highly entangled quantum many-body states. Analogous to optimal steering of i…
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…
Anomalously fast transport in non-integrable lattice gauge theories
Devendra Singh Bhakuni, Roberto Verdel, Jean-Yves Desaules +3
Kinetic constraints are generally expected to slow down dynamics in many-body systems, obstructing or even completely suppressing transport of conserved charges. Here, we show how…
Quasi-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. In quantum many-body systems,…
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…
Finite steady-state current defies non-Hermitian many-body localization
Pietro Brighi, Marko Ljubotina, Federico Roccati +1
Non-Hermitian many-body localization (NH MBL) has emerged as a possible scenario for stable localization in open systems, as suggested by spectral indicators identifying a putative…
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.…
Probing the many-body localized spin-glass phase through quench dynamics
Pietro Brighi, Marko Ljubotina, Maksym Serbyn
Eigenstates of quantum many-body systems are often used to define phases of matter in and out of equilibrium; however, experimentally accessing highly excited eigenstates is a chal…
Quantum Many-Body Scars beyond the PXP model in Rydberg simulators
Aron Kerschbaumer, Marko Ljubotina, Maksym Serbyn +1
Persistent revivals recently observed in Rydberg atom simulators have challenged our understanding of thermalization and attracted much interest to the concept of quantum many-body…
Quantum many-body spin ratchets
Lenart Zadnik, Marko Ljubotina, Žiga Krajnik +2
Introducing a class of SU(2) invariant quantum unitary circuits generating chiral transport, we examine the role of broken space-reflection and time-reversal symmetries on spin tra…
Anomalous transport in the kinetically constrained quantum East-West model
Pietro Brighi, Marko Ljubotina
We study a chaotic particle-conserving kinetically constrained model, with a single parameter which allows us to break reflection symmetry. Through extensive numerical simulations…
Tangent space generators of matrix product states and exact Floquet quantum scars
Marko Ljubotina, Elena Petrova, Norbert Schuch +1
The advancement of quantum simulators motivates the development of a theoretical framework to assist with efficient state preparation in quantum many-body systems. Generally, prepa…
Many-body entropies and entanglement from polynomially-many local measurements
Benoît Vermersch, Marko Ljubotina, J. Ignacio Cirac +3
Estimating global properties of many-body quantum systems such as entropy or bipartite entanglement is a notoriously difficult task, typically requiring a number of measurements or…
Many-body localization proximity effect in two-species bosonic Hubbard model
Pietro Brighi, Marko Ljubotina, Dmitry A. Abanin +1
The many-body localization (MBL) proximity effect is an intriguing phenomenon where a thermal bath localizes due to the interaction with a disordered system. The interplay of therm…
Hilbert space fragmentation and slow dynamics in particle-conserving quantum East models
Pietro Brighi, Marko Ljubotina, Maksym Serbyn
Quantum kinetically constrained models have recently attracted significant attention due to their anomalous dynamics and thermalization. In this work, we introduce a hitherto unexp…
Superdiffusive Energy Transport in Kinetically Constrained Models
Marko Ljubotina, Jean-Yves Desaules, Maksym Serbyn +1
Universal nonequilibrium properties of isolated quantum systems are typically probed by studying transport of conserved quantities, such as charge or spin, while transport of energ…
Optimal steering of matrix product states and quantum many-body scars
Marko Ljubotina, Barbara Roos, Dmitry A. Abanin +1
Ongoing development of quantum simulators allows for a progressively finer degree of control of quantum many-body systems. This motivates the development of efficient approaches to…
