Quantum vs thermal fluctuations in phase transitions of two-dimensional superconductors
Andrea Ponticelli, Francesco Giuseppe Capone, Vittorio Cataudella +3
We investigate the impact of quantum and thermal phase fluctuations on the suppression of superconducting order in two-dimensional systems. Within the two-dimensional quantum XY mo…
Witnessing Environment Induced Topological Phase Transitions via Quantum Monte Carlo and Cluster Perturbation Theory Studies
F. Pavan, A. de Candia, G. Di Bello +4
Many-body interactions play a crucial role in quantum topological systems, being able to impact or alter the topological classifications of non-interacting fermion systems. In open…
Dissipation driven dynamical topological phase transitions in two-dimensional superconductors
Andrea Nava, Carmine Antonio Perroni, Reinhold Egger +2
We induce and study a topological dynamical phase transition between two planar superconducting phases. Using the Lindblad equation to account for the interactions of Bogoliubov qu…
Lindblad master equation approach to the dissipative quench dynamics of planar superconductors
Andrea Nava, Carmine Antonio Perroni, Reinhold Egger +2
We employ the Lindblad master equation method to study the nonequilibrium dynamics following a parametric quench in the Hamiltonian of an open, two-dimensional superconducting syst…
Interplay between singlet and triplet pairings in multi-band two-dimensional oxide superconductors
L. Lepori, D. Giuliano, A. Nava +1
We theoretically study the superconducting properties of multi-band two-dimensional transition metal oxide superconductors by analyzing not only the role played by conventional sin…
Ground state features and spectral properties of large polaron liquids from low to high charge densities
C. A. Perroni, G. De Filippis, V. Cataudella
A new variational approach is proposed at zero temperature for a finite density of charge carriers in order to study ground state features of the Frohlich model including electron-…
