Energy partitioning of wave packets in one-dimensional systems
Flavia B. Ramos, Imke Schneider, Sebastian Eggert +1
We investigate the non-equilibrium dynamics of wave packets in a one-dimensional critical fermionic system and analyze the resulting partitioning of energy between emergent excitat…
Resonant excitations via low frequency pumping in driven magnon systems
Jan Mathis Giesen, Alexandre Abbass Hamadeh, Imke Schneider +2
We analyse resonant excitations of ferromagnetic magnons via microwave pumping using Floquet theory. Special focus is put on driving frequencies that are below the corresponding ma…
Tailored dissipation for directional transport in plasmonic ratchets
Anna Sidorenko, Jan Mathis Giesen, Sebastian Eggert +1
We present a joint experimental and theoretical study of a ratchet implemented in arra ys of evanescently coupled plasmonic waveguides with tailored losses. In this setup the time-…
Topological Defects from Quantum Reset Dynamics
R. Jafari, Henrik Johannesson, Sebastian Eggert
We analyze mechanisms for universal out-of-equilibrium dynamics near criticality by exploring the effect of randomized quantum resetting (QR) under a finite-time quench across a qu…
Competition between dimerization and vector chirality in the spin- - Heisenberg chain with uniaxial single-ion anisotropy
Ji-Lu He, Sebastian Eggert, Haiqing Lin +2
The spin- chain is a versatile prototypical platform for the study of competition between different kinds of magnetic orders, with the objective of obtaining a deeper understa…
Nonlinear effects on charge fractionalization in critical chains
Flávia B. Ramos, Rodrigo G. Pereira, Sebastian Eggert +1
We investigate the generic transport in a one-dimensional strongly correlated fermionic chain beyond linear response. Starting from a Gaussian wave packet with positive momentum on…
Dynamical quantum phase transitions following a noisy quench
R. Jafari, A. Langari, S. Eggert +1
We study how time-dependent energy fluctuations impact the dynamical quantum phase transitions (DQPTs) following a noisy ramped quench of the transverse magnetic field in a quantum…
Speeding Up Squeezing with a Periodically Driven Dicke Model
Jarrod T. Reilly, Simon B. Jäger, John Drew Wilson +3
We present a simple and effective method to create highly entangled spin states on a faster timescale than that of the commonly employed one-axis twisting (OAT) model. We demonstra…
Dissipative Dicke time crystals: an atoms' point of view
Simon B. Jäger, Jan Mathis Giesen, Imke Schneider +1
We develop and study an atom-only description of the Dicke model with time-periodic couplings between atoms and a dissipative cavity mode. The cavity mode is eliminated giving rise…
