Work statistics and Entanglement across the fermionic superfluid-insulator transition
Krissia Zawadzki, Guilherme A. Canella, Vivian V. França +1
Entanglement in many-body systems may display interesting signatures of quantum phase transitions and similar properties are starting to be encountered in the analysis of work fluc…
Many Body Density of States of a system of non interacting spinless fermions
Rémi Lefèvre, Krissia Zawadzki, Grégoire Ithier
The modeling of out-of-equilibrium many-body systems requires to go beyond the low-energy physics and local densities of states. Many-body localization, presence or lack of thermal…
Non-Gaussian work statistics at finite-time driving
Krissia Zawadzki, Anthony Kiely, Gabriel T. Landi +1
We study properties of the work distribution of a many-body system driven through a quantum phase transition in finite time. We focus on the non-Gaussianity of the distribution, wh…
Effects of Temperature and Magnetization on the Mott-Anderson Physics in one-dimensional Disordered Systems
G. A. Canella, K. Zawadzki, V. V. França
We investigate the Mott-Anderson physics in interacting disordered one-dimensional chains through the average single-site entanglement quantified by the linear entropy, which is ob…
Beyond perturbation theory: A time-dependent approach to inelastic scattering spectroscopies in- and away from equilibrium
Krissia Zawadzki, Luhang Yang, Adrian E. Feiguin
We propose a non-perturbative numerical approach to calculate the spectrum of a many-body Hamiltonian with time and momentum resolution by exactly recreating a scattering event usi…
A time-dependent scattering approach to core-level spectroscopies
Krissia Zawadzki, Alberto Nocera, Adrian E. Feiguin
While new light sources allow for unprecedented resolution in experiments with X-rays, a theoretical understanding of the scattering cross-section is lacking. In the particular cas…
Work-distribution quantumness and irreversibility when crossing a quantum phase transition in finite time
Krissia Zawadzki, Roberto M. Serra, Irene D'Amico
The thermodynamic behavior of out-of-equilibrium quantum systems in finite-time dynamics encompasses the description of energy fluctuations, which dictates a series of system's phy…
Time and momentum-resolved tunneling spectroscopy of pump-driven non-thermal excitations in Mott insulators
Krissia Zawadzki, Adrian E. Feiguin
We present a computational technique to calculate time and momentum resolved non-equilibrium spectral density of correlated systems using a tunneling approach akin scanning tunneli…
Many-body effects on the thermodynamics of closed quantum systems
A. H. Skelt, K. Zawadzki, I. D'Amico
Thermodynamics of quantum systems out-of-equilibrium is very important for the progress of quantum technologies, however, the effects of many body interactions and their interplay…
How sharply does the Anderson model depict a single-electron transistor?
Krissia Zawadzki, Luiz N. Oliveira
The single-impurity Anderson model has been the focus of theoretical studies of molecular junctions and the single-electron transistor, a nanostructured device comprising a quantum…
Melting a Hubbard dimer: benchmarks of `ALDA' for quantum thermodynamics
Marcela Herrera, Krissia Zawadzki, Irene D'Amico
The competition between evolution time, interaction strength, and temperature challenges our understanding of many-body quantum systems out-of-equilibrium. Here we consider a bench…
Entanglement in finite quantum systems under twisted boundary conditions
Krissia Zawadzki, Irene D'Amico, Luiz N. Oliveira
In a recent publication, we have discussed the effects of boundary conditions in finite quantum systems and their connection with symmetries. Focusing on the one-dimensional Hubbar…
Symmetries and boundary conditions with a twist
Krissia Zawadzki, Luiz Nunes de Oliveira, Irene D'Amico
Interest in finite-size systems has risen in the last decades, due to the focus on nanotechnological applications and because they are convenient for numerical treatment that can s…
Investigating the Morphological Categories in the NeuroMorpho Database by Using Superparamagnetic Clustering
Krissia Zawadzki, Mauro Miazaki, Luciano da F. Costa
The continuing neuroscience advances, catalysed by multidisciplinary collaborations between the biological, computational, physical and chemical areas, have implied in increasingly…
