Unraveling the Emergence of Slow Dynamics in U(1) Lattice Gauge Theories
Riccardo Andreoni, Zala Lenarčič, Zeno Bacciconi +3
The dynamics of gauge theories is of fundamental interest, with low-dimensional systems displaying a rich phenomenology beyond the rapid thermalization typical of QCD and non-Abeli…
Non-equilibrium dissipative stabilization of s- and d-wave superconductivity
Aleksey Lunkin, Yury Holubeu, Denis Golež +1
Stabilizing superconductivity beyond its equilibrium regime has been one of the quests of nonequilibrium state engineering. We report the presence of nonthermal pairing gap in BCS…
Nonlinear Fluctuating Hydrodynamics from Interacting Noisy Quantum Matter
Alexios Christopoulos, João Costa, Stefano Scopa +4
A universal characterization of non-equilibrium steady states in interacting quantum many-body systems remains one of the central challenges of statistical physics. Here, we addres…
Dissipative framework for subsystem dynamics of noninteracting quantum chains
Michele Coppola, Zala Lenarčič
When only local observables of a many-body quantum system are of interest, it is desirable to formulate a reduced description within the Hilbert space of the corresponding subsyste…
Learning the non-Markovian features of subsystem dynamics
Michele Coppola, Mari Carmen Bañuls, Zala Lenarčič
The dynamics of local observables in a quantum many-body system can be formally described in the language of open systems. The problem is that the bath representing the complement…
A Hubbard exciton fluid in a photo-doped antiferromagnetic Mott insulator
Omar Mehio, Xinwei Li, Honglie Ning +7
The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice site. When it is doped with additional carriers, they are unstable to spin fluctuation-med…
Generalized Gibbs ensembles in weakly interacting dissipative systems and digital quantum computers
Iris Ulčakar, Zala Lenarčič
Identifying use cases with superconducting circuits not critically affected by the inherent noise is a pertinent challenge. Here, we propose using a digital quantum computer to sho…
Floquet engineering of binding in doped and photo-doped Mott insulators
Madhumita Sarkar, Zala Lenarčič, Denis Golež
We investigate the emergence of bound states in chemically and photo-doped Mott insulators, mediated by spin and -pairing fluctuations within both 2-leg ladder and 2D systems. T…
Emergent dipole moment conservation and subdiffusion in tilted chains
S. Nandy, J. Herbrych, Z. Lenarčič +3
We study the transport dynamics of an interacting tilted (Stark) chain. We show that the crossover between diffusive and subdiffusive dynamics is governed by , where …
Iterative construction of conserved quantities in dissipative nearly integrable systems
Iris Ulčakar, Zala Lenarčič
Integrable systems offer rare examples of solvable many-body problems in the quantum world. Due to the fine-tuned structure, their realization in nature and experiment is never com…
Reconstructing effective Hamiltonians from nonequilibrium (pre-)thermal steady states
Sourav Nandy, Markus Schmitt, Marin Bukov +1
Reconstructing Hamiltonians from local measurements is key to enabling reliable quantum simulation: both validating the implemented model, and identifying any left-over terms with…
Spin-1/2 XXZ chain coupled to two Lindblad baths: Constructing nonequilibrium steady states from equilibrium correlation functions
Tjark Heitmann, Jonas Richter, Fengping Jin +7
State-of-the-art approaches to extract transport coefficients of many-body quantum systems broadly fall into two categories: (i) they target the linear-response regime in terms of…
Spin diffusion in perturbed isotropic Heisenberg spin chain
S. Nandy, Z. Lenarčič, E. Ilievski +3
The isotropic Heisenberg chain represents a particular case of an integrable many-body system exhibiting superdiffusive spin transport at finite temperatures. Here, we show that th…
From dissipationless to normal diffusion in easy-axis Heisenberg spin chain
P. Prelovšek, S. Nandy, Z. Lenarčič +2
The anomalous spin diffusion of the integrable easy-axis Heisenberg chain originates in the ballistic transport of symmetry sectors with nonzero magnetization. Ballistic transport…
From observations to complexity of quantum states via unsupervised learning
Markus Schmitt, Zala Lenarčič
The vast complexity is a daunting property of generic quantum states that poses a significant challenge for theoretical treatment, especially in non-equilibrium setups. Therefore,…
Engineering generalized Gibbs ensembles with trapped ions
Florentin Reiter, Florian Lange, Shreyans Jain +3
The concept of generalized Gibbs ensembles (GGEs) has been introduced to describe steady states of integrable models. Recent advances show that GGEs can also be stabilized in nearl…
Critical behavior near the many-body localization transition in driven open systems
Zala Lenarčič, Ori Alberton, Achim Rosch +1
Coupling a many-body localized system to a thermal bath breaks local conservation laws and washes out signatures of localization. When the bath is non-thermal or when the system is…
Activating many-body localization in solids by driving with light
Zala Lenarčič, Ehud Altman, Achim Rosch
Due to the presence of phonons, many body localization (MBL) does not occur in disordered solids, even if disorder is strong. Local conservation laws characterizing an underlying M…
Time-dependent generalized Gibbs ensembles in open quantum systems
Florian Lange, Zala Lenarčič, Achim Rosch
Generalized Gibbs ensembles have been used as powerful tools to describe the steady state of integrable many-particle quantum systems after a sudden change of the Hamiltonian. Here…
Pumping approximately integrable systems
Florian Lange, Zala Lenarčič, Achim Rosch
Weak perturbations can drive an interacting many-particle system far from its initial equilibrium state if one is able to pump into degrees of freedom approximately protected by co…
Exciton Recombination in One-Dimensional Organic Mott Insulators
Zala Lenarčič, Martin Eckstein, Peter Prelovšek
We present a theory for the recombination of (charged) holons and doublons in one-dimensional organic Mott insulators, which is responsible for the decay of a photoexcited metallic…
Holon-Doublon Binding as the Mechanism for the Mott transition
Peter Prelovšek, Jure Kokalj, Zala Lenarčič +1
We study the binding of a holon to a doublon in a half-filled Hubbard model as the mechanism of the zero-temperature metal-insulator transition. In a spin polarized system and a no…
