The physics of one-dimensional interacting bosonic systems is reviewed. Beginning with
results from exactly solvable models and computational approaches, the concept of bosonic …

The ability to generate particles from the quantum vacuum is one of the most profound
consequences of Heisenberg's uncertainty principle. Although the significance of vacuum …

For a system at a temperature of absolute zero, all thermal fluctuations are frozen out, while
quantum fluctuations prevail. These microscopic quantum fluctuations can induce a …

This book presents a complete encyclopedia of superconducting fluctuations, summarising
the last thirty-five years of work in the field. The first part of the book is devoted to an …

Josephson-junction arrays are ideal model systems to study a variety of phenomena such as
phase transitions, frustration effects, vortex dynamics and chaos. In this review, we focus on …

We study the one-dimensional Bose-Hubbard model using the density-matrix
renormalization group. For the cases of on-site interactions and additional nearest-neighbor …

The current understanding of the superconductor–insulator transition is discussed level by
level in a cyclic spiral-like manner. At the first level, physical phenomena and processes are …

We have measured the plasma resonances of an array of Josephson junctions in the regime
EJ≫ EC, up to the ninth harmonic by incorporating it as part of a resonator capacitively …

We investigate critical quantum metrology, that is, the estimation of parameters in many-
body systems close to a quantum critical point, through the lens of Bayesian inference …

The polarization field of the ferroelectric oxide lead zirconate titanate [Pb (ZrxTi1–x) O3] was
used to tune the critical temperature of the hightemperature superconducting cuprate …
