Nonequilibrium quantum phase transitions in the XY model: comparison of unitary time evolution and reduced density operator approaches
(IOP Publishing, 2014)
We study nonequilibrium quantum phase transitions in the XY spin 1/2 chain
using the C* algebra. We show that the well-known quantum phase transition at
a magnetic field of h = 1 also persists in the nonequilibrium setting ...
Dynamical phase transitions and Loschmidt echo in the infinite-range XY model
(Royal Soc, 2016)
We compare two different notions of dynamical phase transitions in closed quantum systems. The first is identified through the time-averaged value of the equilibrium-order parameter, whereas the second corresponds to ...

Collective and optical phenomena in equilibrium and nonequilibrium interacting quantum systems
(Universidade Federal de Minas GeraisUFMG, 2014-11-13)
In this thesis we study collective, emergent and optical properties of interacting quantum systems both in equilibrium and nonequilibrium situations from a microscopic modelling. This orientation steams from both the fact ...
Feasibility of the ion-trap simulation of a class of non-equilibrium phase transitions
(Springer, 2019-11)
Our work analyzes the potential of ion traps for the experimental simulation of non-equilibrium phase transitions observed in certain spin-chain models which can be mapped to free-fermion systems. In order to make the ...
Nonequilibrium Dynamics of the Chiral Quark Condensate under a Strong Magnetic Field
(Mdpi, 2021-04-01)
Strong magnetic fields impact quantum-chromodynamics (QCD) properties in several situations; examples include the early universe, magnetars, and heavy-ion collisions. These examples share a common trait-time evolution. A ...
