Abstract
The transfer of excitations between different locations of a quantum many-body system is of primary importance in many research areas, from transport properties in spintronics and atomtronics to quantum state transfer in quantum information processing. We address the transfer of n > 1 bosonic and fermionic excitations between the edges of a one-dimensional chain modelled by a quadratic hopping Hamiltonian, where the block edges, embodying the sender and the receiver sites, are weakly coupled to the quantum wire. We find that perturbative high-quality transfer is attainable in the weak-coupling limit, for both bosons and fermions, only for certain modular arithmetic equivalence classes of the wire’s length. Finally we apply our findings to the transport of spins and the charging of a many-body quantum battery.
Highlights
Quantum many-body dynamics lies at the core of most of theoretical and experimental physics [1]
Applications of quantum many-body dynamics are found in countless technologies, ranging from electronics to spintronics where characterising transport properties is of paramount importance [2, 3]
We have investigated the many-body transfer of bosonic and fermionic excitations in a one-dimensional open chain modelled by a nearest-neighbour hopping Hamiltonian
