Hamiltonian transformability, fast adiabatic dynamics and hidden adiabaticity
(Springer Nature, 2021-02-25)We prove the existence of a unitary transformation that enables two arbitrarily given Hamiltonians in the same Hilbert space to be transformed into one another. The result is straightforward yet, for example, it lays the ... -
Hartle's model within the general theory of perturbatiye matchings: the change in mass
; Vera Jiménez, Raül
(IOP Publishing, 2015)
Hartle's model provides the most widely used analytic framework to describe isolated compact bodies rotating slowly in equilibrium up to second order in perturbations in the context of General Relativity. Apart from some ... -
High- fi delity non-adiabatic cutting and stitching of a spin chain via local control
(IOP Publishing, 2018-10-18)We propose and analyze, focusing on non-adiabatic effects, a technique of manipulating quantum spin systems based on local 'cutting' and 'stitching' of the Heisenberg exchange coupling between the spins. This first operation ... -

Measurement-induced, spatially-extended entanglement in a hot, strongly-interacting atomic system
