We study the dynamics of phase relaxation between a pair of one-dimensional condensates created by a supersonic unzipping of a single condensate. We use the Lorentz invariance of the low energy sector of such systems to show that dephasing results in an unusual prethermal state, in which right- and left-moving excitations have different, Doppler-shifted temperatures. The chirality of these modes can be probed experimentally by measuring the interference fringe contrasts with the release point…

Quantum simulation of expanding space-time with tunnel-coupled condensates
We consider two weakly interacting quasi-1D condensates of cold bosonic atoms. It turns out that a time-dependent variation of the tunnel-coupling between those condensates is equivalent with the
Prethermalization and thermalization of a quenched interacting Luttinger liquid
We study the relaxation dynamics of interacting one-dimensional fermions with band curvature after a weak quench in the interaction parameter at zero temperature. Our model lies within the class of
Quantum quenches to the attractive one-dimensional Bose gas: exact results
We study quantum quenches to the one-dimensional Bose gas with attractive interactions in the case when the initial state is an ideal one-dimensional Bose condensate. We focus on properties of the
Relaxation and Prethermalization in One-Dimensional Bose Gases
The study of relaxation processes remains a challenge despite considerable theoretical and experimental efforts. In this chapter, we study such processes using a 1D Bose gas. The system is quenched
Fast Preparation of Critical Ground States Using Superluminal Fronts.
A spatiotemporal quench protocol that allows for the fast preparation of ground states of gapless models with Lorentz invariance is proposed, and proof of concept by solving the proposed quench exactly for a system of free bosons in arbitrary dimensions, and for free fermions in d=1.
Ultracold Atoms Out of Equilibrium
The relaxation of isolated quantum many-body systems is a major unsolved problem connecting statistical and quantum physics. Studying such relaxation processes remains a challenge despite
Nonequilibrium Criticality in Quench Dynamics of Long-Range Spin Models.
A prototype of infinite-range interacting models known as the Lipkin-Meshkov-Glick model is considered describing the collective interaction of N spins and the dynamical properties of fluctuations and correlations after a sudden quench of the Hamiltonian are investigated.
Kinetic theory for interacting Luttinger liquids
We derive a closed set of equations for the kinetics and non-equilibrium dynamics of interacting Luttinger Liquids with cubic resonant interactions. In the presence of these interactions, the
Cooling arbitrary near-critical systems using hyperbolic quenches
We describe a quench protocol that allows the rapid preparation of ground states of arbitrary interacting conformal field theories in $1+1$ dimensions. We start from the ground state of a related


Quantum Fields in Curved Space
This book presents a comprehensive review of the subject of gravitational effects in quantum field theory. Although the treatment is general, special emphasis is given to the Hawking black hole
Atom chips.
The next big challenge is manipulating single atoms, allowing them to have controlled collisions and coupling them to single photons in optical microcavities, which will lead to new quantum devices and ultimately to quantum information processing on a chip.

Introduction to quantum field theory
Even the uninitiated will know that Quantum Field Theory cannot be introduced systematically in just four lectures. I try to give a reasonably connected outline of part of it, from second
It is shown that the full set of hydromagnetic equations admit five more integrals, besides the energy integral, if dissipative processes are absent, which made it possible to formulate a variational principle for the force-free magnetic fields.
