Genuine many-body quantum scars along unstable modes in Bose-Hubbard systems
Quirin Hummel, Klaus Richter, Peter Schlagheck
The notion of many-body quantum scars is associated with special eigenstates, usually concentrated in certain parts of Hilbert space, that give rise to robust persistent oscillatio…
Symmetry-induced many-body quantum interference in chaotic bosonic systems: an augmented Truncated Wigner method
Quirin Hummel, Peter Schlagheck
Although highly successful, the Truncated Wigner Approximation (TWA) does not account for genuine many-body quantum interference between different solutions of the mean-field equat…
Partial Fermionization---Spectral Universality in 1D Repulsive Bose Gases
Quirin Hummel, Juan Diego Urbina, Klaus Richter
Due to the vast growth of the many-body level density with excitation energy, its smoothed form is of central relevance for spectral and thermodynamic properties of interacting qua…
Nonlocal pair correlations in Lieb-Liniger gases: A unified nonperturbative approach from weak degeneracy to high temperatures
Benjamin Geiger, Quirin Hummel, Juan Diego Urbina +1
We present analytical results for the nonlocal pair correlations in one-dimensional bosonic systems with repulsive contact interactions that are uniformly valid from the classical…
Semiclassics in a system without classical limit: The few-body spectrum of two interacting bosons in one dimension
Benjamin Geiger, Juan-Diego Urbina, Quirin Hummel +1
We present a semiclassical study of the spectrum of a few-body system consisting of two short-range interacting bosonic particles in one dimension, a particular case of a general c…
