Emergent hydrodynamic response and dynamical backreaction: Magnon bound-state propagation in a Bose-Hubbard fluid
Andrés N. Cáliz, Arnau Riera, Enrique Rico +2
We study the nonequilibrium response of a one-dimensional Bose-Hubbard medium to a two-magnon bound state propagating along an attractive XXZ chain. A Holstein-type displacement co…
Dressed magnon dynamics in a Bose-Hubbard bath: retardation, pairing, entanglement and two-magnon scattering
Andrés N. Cáliz, Arnau Riera, Enrique Rico +2
We study one- and two-magnon dynamics in a spin- XX chain coupled to a tunable Bose-Hubbard bath. The XX Hamiltonian transports the magnons, while the bath dresses their motio…
Quantum Operations in an Information Theory for Fermions
Nicetu Tibau Vidal, Mohit Lal Bera, Arnau Riera +2
A reasonable quantum information theory for fermions must respect the parity super-selection rule to comply with the special theory of relativity and the no-signaling principle. Th…
Resource theory of heat and work with non-commuting charges
Zahra Baghali Khanian, Manabendra Nath Bera, Arnau Riera +2
We consider a theory of quantum thermodynamics with multiple conserved quantities (or charges). To this end, we generalize the seminal results of Sparaciari et al. [PRA 96:052112,…
Quantum equilibration of a model system Porphine
Guillermo Albareda, Arnau Riera, Miguel Gonzalez +4
There is a renewed interest in the derivation of statistical mechanics from the dynamics of closed quantum systems. A central part of this program is to understand how far-from-equ…
Bounds on the capacity and power of quantum batteries
Sergi Julia-Farre, Tymoteusz Salamon, Arnau Riera +2
Quantum batteries, composed of quantum cells, are expected to outperform their classical analogs. The origin of such advantages lies in the role of quantum correlations, which may…
