Conventional hydrodynamics describes systems with few long-lived excitations. In one
dimension, however, many experimentally relevant systems feature a large number of long …

We investigate a time-efficient and robust preparation of spin-squeezed states—a class of
states of interest for quantum enhanced metrology—in internal bosonic Josephson junctions …

The twist-and-turn dynamics of spin squeezing results from the interplay of the one-axis-
twisting (nonlinear in the collective-spin operators) and the transverse-field turning (linear) …

We implement two types of matter-wave interferometers using trapped Bose-condensed
Feshbach molecules, from weak to strong interactions. In each case, we focus on …

We study the Josephson junction made of a one-dimensional ultradilute quantum liquid in a
double-well potential. We analyze the dynamics as a function of the interaction strength and …

Fragmentation of an interacting Bose gas refers to the macroscopic occupation of a finite set
of single-particle eigenstates. This phenomenon is related to the notion of particle-number …

The efficient readout of the relevant information is pivotal for quantum simulation
experiments. Often only single observables are accessed by performing standard projective …

We study the dynamics and decay of quantum phase coherence for Bose-Einstein
condensates in tunnel-coupled quantum wires. The two elongated Bose-Einstein …

We study the ponderomotive potential of a bosonic Josephson junction periodically
modulated by a high-frequency electromagnetic field. Within the small population difference …

Bosonic Josephson junctions (BJJs) have been realised across various platforms and their
dynamics have been extensively studied since their first discovery in the 1990s. While prior …
