In recent years, controlled dissipation has proven to be a useful tool for the probing of a quantum system in an ultracold setup. In this paper we consider the dynamics of bosons induced by a dissipative local defect. We address superfluid and supersolid phases close to half filling that are ground states of an extended Bose-Hubbard Hamiltonian. To this end, we solve the master equation using the Gutzwiller approximation and find that in the superfluid phase repulsive nearest-neighbor… 
Interacting bosons in two-dimensional lattices with localized dissipation
Motivated by the recent experiment [Takafumi Tomita \emph{et al.}, Sci. Adv. {\bf 3}, (2017)], we study the dynamics of interacting bosons in a two-dimensional optical lattice with local dissipation.
Fluctuation-Induced Quantum Zeno Effect.
TLDR
This work investigates the effect of a local dissipative impurity on a one-dimensional gas of interacting fermions and shows that the escape probability for modes close to the Fermi energy vanishes for an arbitrary strength of the dissipation.
The dissipative Bose-Hubbard model
Open many-body quantum systems have attracted renewed interest in the context of quantum information science and quantum transport with biological clusters and ultracold atomic gases. The physical
Density-wave steady-state phase of dissipative ultracold fermions with nearest-neighbor interactions
In this work we investigate the effect of local dissipation on the presence of density-wave ordering in spinful fermions with both local and nearest-neighbor interactions as described by the extended
Observation of the Mott insulator to superfluid crossover of a driven-dissipative Bose-Hubbard system
TLDR
The controllability of the dissipation is highlighted by quenching the Dissipation, providing a novel method for investigating a quantum many-body state and its nonequilibrium dynamics.
Ultracold quantum wires with localized losses: Many-body quantum Zeno effect
We study a one-dimensional system of interacting spinless fermions subject to a localized loss, where the interplay of gapless quantum fluctuations and particle interactions leads to an incarnation
Dissipative two-mode Bose–Einstein condensate coupled to the environment
We study the dynamics of an atomic condensate loaded in two symmetric traps where one of the trap is coupled to a reservoir. Analytical solution of the population dynamics is given for the
Quasiparticle spectra of supersolid lattice gases at near-resonant Rydberg dressing
One of the major challenges in realizing a strongly interacting lattice gas using Rydberg states is the occurrence of avalanche loss processes. As these are directly proportional to the total Rydberg
Particle statistics and lossy dynamics of ultracold atoms in optical lattices
Experimental control over ultracold quantum gases has made it possible to investigate low-dimensional systems of both bosonic and fermionic atoms. In closed one-dimensional systems there are many
Dynamics of the double-well Bose–Einstein condensate coupled to a dual Markovian reservoirs system
The dynamics of atomic condensate loaded in a double-well symmetric traps coupled to distinct dual reservoirs is studied. The effect of damping on the population evolution through the exposure of
