Spectroscopic Signatures of a Liouvillian Exceptional Spectral Phase in a Collective Spin
Rafael A. Molina
Non-Hermitian degeneracies of Lindblad generators (Liouvillian exceptional points) can induce non-exponential relaxation and higher-order poles in dynamical response functions. A c…
Role of exceptional points in the dynamics of the Lindblad Sachdev-Ye-Kitaev model
Jie-ping Zheng, Jorge Dukelsky, Rafael A. Molina +1
The out of equilibrium dynamics of the Sachdev-Ye-Kitaev model (SYK), comprising Majoranas with random all-to-all four-body interactions, minimally coupled to a Markovian bath…
Controlled localization of interacting bosons in a disordered optical lattice
J. Santos, R. A. Molina, J. Ortigoso +1
We show that tunneling and localization properties of interacting ultracold atoms in an optical lattice can be controlled by adiabatically turning on a fast oscillatory force even…
Decoherence induced by an interacting spin environment in the transition from integrability to chaos
A. Relano, J. Dukelsky, R. A. Molina
We investigate the decoherence properties of a central system composed of two spins 1/2 in contact with a spin bath. The dynamical regime of the bath ranges from a fully integrable…
Localization properties of driven disordered one-dimensional systems
Dario F. Martinez, Rafael A. Molina
We generalize the definition of localization length to disordered systems driven by a time-periodic potential using a Floquet-Green function formalism. We study its dependence on t…
Theoretical derivation of 1/f noise in quantum chaos
E. Faleiro, J. M. G. Gómez, R. A. Molina +4
It was recently conjectured that 1/f noise is a fundamental characteristic of spectral fluctuations in chaotic quantum systems. This conjecture is based on the behavior of the powe…
