Variational Multi-Gaussian Phase-Space Dynamics via Automatic Differentiation
Jacopo Tosca, Francesco Carnazza, Luca Giacomelli +1
The paper presents a variational multi-Gaussian approach for simulating the dynamics of interacting open quantum bosonic systems, using a Wigner phase-space representation and auto…
Analogue gravity with Bose-Einstein condensates
Adrià Delhom, Luca Giacomelli
Analogue gravity explores how collective excitations in condensed matter systems can reproduce the behavior of fields in curved spacetimes. An important example is the acoustic bla…
Tunable lower critical fractal dimension for a non-equilibrium phase transition
Mattheus Burkhard, Luca Giacomelli, Cristiano Ciuti
We theoretically investigate the role of spatial dimension and driving frequency in a non-equilibrium phase transition of a driven-dissipative interacting bosonic system. In this s…
Exact Duality at Low Energy in a Josephson Tunnel Junction Coupled to a Transmission Line
Luca Giacomelli, Michel H. Devoret, Cristiano Ciuti
We theoretically explore the low-energy behavior of a Josephson tunnel junction coupled to a finite-length, charge-biased transmission line and compare it to its flux-biased counte…
Resilience of the quantum critical line in the Schmid transition
Nicolas Paris, Luca Giacomelli, Romain Daviet +3
Schmid predicted that a single Josephson junction coupled to a resistive environment undergoes a quantum phase transition to an insulating phase when the shunt resistance excee…
Circuit QED theory of direct and dual Shapiro steps with finite-size transmission line resonators
Federico Borletto, Luca Giacomelli, Cristiano Ciuti
We investigate the occurrence of direct and dual Shapiro steps for a Josephson junction coupled to a finite-size transmission line resonator. We treat both problems through a circu…
