Many-body theory of false vacuum decay in quantum spin chains
Christian Johansen, Alessio Recati, Iacopo Carusotto +1
In this work we theoretically investigate the false vacuum decay process in a ferromagnetic quantum spin-1/2 chain. We develop a many-body theory describing the nucleation and the…
Ballistic transport and boundary resistances in inhomogeneous quantum spin chains
Alberto Biella, Mario Collura, Davide Rossini +2
Transport phenomena are central to physics, and transport in the many-body and fully-quantum regime is attracting an increasing amount of attention. It has been recently revealed t…
Phase diagram of the dissipative quantum Ising model on a square lattice
Jiasen Jin, Alberto Biella, Oscar Viyuela +3
The competition between interactions and dissipative processes in a quantum many-body system can drive phase transitions of different order. Exploiting a combination of cluster met…
Linked cluster expansions for open quantum systems on a lattice
Alberto Biella, Jiasen Jin, Oscar Viyuela +3
We propose a generalization of the linked-cluster expansions to study driven-dissipative quantum lattice models, directly accessing the thermodynamic limit of the system. Our metho…
