Smeared phase transition in the dissipative random quantum Ashkin-Teller model
Pedro S. Farinas, Rajesh Narayanan, José A. Hoyos
We study the effects of dissipation in the phase diagram of the random quantum Ashkin-Teller model by means of a generalization of the strong-disorder renormalization group combine…
Signatures of infinite randomness in transport properties of disordered spin chains
L. F. C. Faria, Victor L. Quito, João C. Getelina +2
We study the spin transport properties of some disordered spin chains with a special focus on the distribution of the frequency-dependent spin conductivity. In the cases of interes…
Random free-fermion quantum spin chain with multi-spin interactions
Francisco C. Alcaraz, José A. Hoyos, Rodrigo A. Pimenta
We study the effects of quenched disorder in a class of quantum chains with (p+1)-multispin interactions exhibiting a free fermionic spectrum, paying special attention to the case…
Effect of long-range hopping on dynamic quantum phase transitions of an exactly solvable free-fermion model: Nonanalyticities at almost all times
J. C. Xavier, José A. Hoyos
In this work, we investigate quenches in a free-fermion chain with long-range hopping which decay with the distance with an exponent and has range . By exploring the exact s…
Contact process with aperiodic temporal disorder
Ariel Y. O. Fernandes, José A. Hoyos, André P. Vieira
We investigate the nonequilibrium critical behavior of the contact process with deterministic aperiodic temporal disorder implemented by choosing healing or infection rates accordi…
Disorder-induced dynamical Griffiths singularities after certain quantum quenches
José A. Hoyos, R. F. P. Costa, J. C. Xavier
We demonstrate that in a class of disordered quantum systems the dynamical partition function is not an analytical function in a time window after certain quantum quenches. We rela…
