Report

Photonic quantum metrology with variational quantum optical non-linearities

Autor: Heras, A. Muñoz de las, Tabares, C., Schneider, J. T., Tagliacozzo, L., Porras, D., González-Tudela, A.

Publikováno v: Phys. Rev. Research 6, 013299 (2024)

Photonic quantum metrology harnesses quantum states of light, such as NOON or Twin-Fock states, to measure unknown parameters beyond classical precision limits. Current protocols suffer from two severe limitations that preclude their scalability: the

Entanglement spectrum and quantum phase diagram of the long-range XXZ chain

Autor: Schneider, J. T., Thomson, S. J., Sanchez-Palencia, L.

Publikováno v: Physical Review B 106:1, 014306 (2022)

Entanglement is a central feature of many-body quantum systems and plays a unique role in quantum phase transitions. In many cases, the entanglement spectrum, which represents the spectrum of the density matrix of a bipartite system, contains valuabl

Spreading of Correlations and Entanglement in the Long-Range Transverse Ising Chain

Autor: Schneider, J. T., Despres, J., Thomson, S. J., Tagliacozzo, L., Sanchez-Palencia, L.

Publikováno v: Phys. Rev. Research 3, 012022 (2021)

Whether long-range interactions allow for a form of causality in non-relativistic quantum models remains an open question with far-reaching implications for the propagation of information and thermalization processes. Here, we study the out-of-equili

A Model for Hydrodynamics in Kinetic Field Theory

Autor: Viermann, C., Schneider, J. T., Lilow, R., Fabis, F., Littek, C., Kozlikin, E., Bartelmann, M.

In this work, we introduce an effective model for both ideal and viscous fluid dynamics within the framework of kinetic field theory (KFT). The main application we have in mind is cosmic structure formation where gaseous components need to be gravita

Report

Dynamical topological transitions in the massive Schwinger model with a {\theta}-term

Autor: Zache, T. V., Mueller, N., Schneider, J. T., Jendrzejewski, F., Berges, J., Hauke, P.

Publikováno v: Phys. Rev. Lett. 122, 050403 (2019)

Aiming at a better understanding of anomalous and topological effects in gauge theories out-of-equilibrium, we study the real-time dynamics of a prototype model for CP-violation, the massive Schwinger model with a $\theta$-term. We identify dynamical
