The sine-Gordon model captures the low-energy effective dynamics of a wealth of one-
dimensional quantum systems, stimulating the experimental efforts in building a versatile …

We present the first exact theory and analytical formulas for the large-scale phase
fluctuations in the sine-Gordon model, valid in all regimes of the field theory, for arbitrary …

Analog quantum simulation has the potential to be an indispensable technique in the
investigation of complex quantum systems. In this work, we numerically investigate a one …

Abstract Truncated Conformal Space Approach (TCSA) is a highly efficient method to
compute spectra, operator matrix elements and time evolution in quantum field theories …

We set up a hydrodynamic description of the non-equilibrium dynamics of sine-Gordon
quantum field theory for generic coupling. It is built upon an explicit form of the Bethe Ansatz …

The false vacuum is a metastable state that can occur in quantum field theory, and its decay
was first studied semiclassically by Coleman. In this work, we consider the 1+ 1 dimensional …

The sine-Gordon field theory emerges as the low-energy description in a wealth of quantum
many-body systems. Recent efforts have been directed towards realizing quantum …

We study the nonequilibrium dynamics of the quantum sine-Gordon model describing a pair
of Josephson-coupled one-dimensional bosonic quasicondensates. Motivated by …

We study inhomogeneous quantum quenches in the attractive regime of the sine-Gordon
model. In our protocol, the system is prepared in an inhomogeneous initial state in finite …

Integrable models provide emblematic examples of non-ergodic phenomena. One of their
most distinguished properties are divergent zero-frequency conductivities signalled by finite …
