Ancilla quantum measurements on interacting chains: Sensitivity of entanglement dynamics to the type and concentration of detectors
Elmer V. H. Doggen, Igor V. Gornyi, Alexander D. Mirlin
We consider a quantum many-body lattice system that is coupled to ancillary degrees of freedom (``detectors''), which are periodically measured by means of strong projective measur…
Evolution of many-body systems under ancilla quantum measurements
Elmer V. H. Doggen, Yuval Gefen, Igor V. Gornyi +2
Measurement-induced phase transitions are the subject of intense current research, both from an experimental and a theoretical perspective. We explore the concept of implementing q…
Coexistence of localization and transport in many-body two-dimensional Aubry-André models
Antonio Štrkalj, Elmer V. H. Doggen, Claudio Castelnovo
Whether disordered and quasiperiodic many-body quantum systems host a long-lived localized phase in the thermodynamic limit has been the subject of intense recent debate. While in…
Many-body localization in a tilted potential in two dimensions
Elmer V. H. Doggen, Igor V. Gornyi, Dmitry G. Polyakov
Thermalization in many-body systems can be inhibited by the application of a linearly increasing potential, which is known as Stark many-body localization. Here we investigate the…
Many-body localization in the interpolating Aubry-André-Fibonacci model
Antonio Štrkalj, Elmer V. H. Doggen, Igor V. Gornyi +1
We investigate the localization properties of a spin chain with an antiferromagnetic nearest-neighbour coupling, subject to an external quasiperiodic on-site magnetic field. The qu…
Generalized quantum measurements with matrix product states: Entanglement phase transition and clusterization
Elmer V. H. Doggen, Yuval Gefen, Igor V. Gornyi +2
We propose a method, based on matrix product states, for studying the time evolution of many-body quantum lattice systems under continuous and site-resolved measurement. Both the f…
Many-body localization in large systems: Matrix-product-state approach
Elmer V. H. Doggen, Igor V. Gornyi, Alexander D. Mirlin +1
Recent developments in matrix-product-state (MPS) investigations of many-body localization (MBL) are reviewed, with a discussion of benefits and limitations of the method. This app…
Dynamics of Many-Body Delocalization in the Time-dependent Hartree-Fock Approximation
Paul Pöpperl, Elmer V. H. Doggen, Jonas F. Karcher +2
We explore dynamics of disordered and quasi-periodic interacting lattice models using a self-consistent time-dependent Hartree-Fock (TDHF) approximation, accessing both large syste…
Stark many-body localization: Evidence for Hilbert-space shattering
Elmer V. H. Doggen, Igor V. Gornyi, Dmitry G. Polyakov
We study the dynamics of an interacting quantum spin chain under the application of a linearly increasing field. This model exhibits a type of localization known as Stark many-body…
Slow many-body delocalization beyond one dimension
Elmer V. H. Doggen, Igor V. Gornyi, Alexander D. Mirlin +1
We study the delocalization dynamics of interacting disordered hard-core bosons for quasi-1D and 2D geometries, with system sizes and time scales comparable to state-of-the-art exp…
Many-body delocalization dynamics in long Aubry-André quasiperiodic chains
Elmer V. H. Doggen, Alexander D. Mirlin
We study quench dynamics in an interacting spin chain with a quasi-periodic on-site field, known as the interacting Aubry-André model of many-body localization. Using the time-depe…
Many-body localization and delocalization in large quantum chains
Elmer V. H. Doggen, Frank Schindler, Konstantin S. Tikhonov +4
We theoretically study the quench dynamics for an isolated Heisenberg spin chain with a random on-site magnetic field, which is one of the paradigmatic models of a many-body locali…
Weak Versus Strong Disorder Superfluid-Bose Glass Transition in One Dimension

Using large-scale simulations based on matrix product state and quantum Monte Carlo techniques, we study the superfluid to Bose glass-transition for one-dimensional attractive hard…
Chaos-assisted tunneling in the presence of Anderson localization
Elmer V. H. Doggen, Bertrand Georgeot, Gabriel Lemarié
Tunneling between two classically disconnected regular regions can be strongly affected by the presence of a chaotic sea in between. This phenomenon, known as chaos-assisted tunnel…

Quench-induced delocalization
Elmer V. H. Doggen, Jami J. Kinnunen
We consider the evolution of an initially localized wave packet after a sudden change in the Hamiltonian, i.e.\ a quench. When both bound and scattering eigenstates exist in the po…
One-dimensional Fermi polaron in a combined harmonic and periodic potential
