Quantum and Classical Potts Criticality in Driven-Dissipative Bosonic Lattices
Jacopo Tosca, Zejian Li, Cristiano Ciuti
The emergence of equilibrium universality from intrinsically nonequilibrium dynamics is a fundamental open problem. Bose-Hubbard lattices realized in photonic and circuit-QED platf…
Composite-Fermion Study of Cavity-Modified Fractional Quantum Hall Excitation Gaps
Dalin Boriçi, Nicolas Regnault, Cristiano Ciuti
We investigate how cavity-mediated attractive electron-electron interactions modify the excitation gaps of fractional quantum Hall states within the composite-fermion framework. We…
Strange Luttinger liquids in a cavity-embedded one-dimensional electronic chain
Danh-Phuong Nguyen, Christophe Mora, Cristiano Ciuti
We study a one-dimensional electronic chain coupled to a homogeneous quantized vacuum field and electron-electron interactions. In the absence of the latter, we derive a low-energy…
Ising selector machine by Kerr parametric oscillators
Jacopo Tosca, Cristiano Ciuti, Claudio Conti +1
Ising machines are physical platforms designed to minimize the energy of classical Ising Hamiltonians, yet accessing specific excited states remains an open challenge of both funda…
Variational Dynamics of Open Quantum Spin Systems in Phase Space
Jacopo Tosca, Zejian Li, Francesco Carnazza +1
We introduce a variational method for simulating the dynamics of interacting open quantum spin systems. The method is based on the spin phase-space representation and variationally…

C. Ciuti, G. Scalari, J. Faist
We comment on the preprint arXiv:2511.04744 by Andolina et al.
Variational Multi-Gaussian Phase-Space Dynamics via Automatic Differentiation
Jacopo Tosca, Francesco Carnazza, Luca Giacomelli +1
We introduce a variational method for simulating the dynamics of interacting open quantum bosonic systems deep in the quantum regime. The method is based on a multi-dimensional Wig…
Observation of Cavity-Mediated Nonlinear Landau Fan and Modified Landau Level Degeneracy in Graphene Quantum Transport
Hongxia Xue, Hsun-Chi Chan, Zuzhang Lin +9
Recent studies on cavity-coupled two-dimensional electron gas demonstrate that vacuum-field engineering can tailor electronic transport properties of materials. By achieving ultra-…
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…
Emergent Equilibrium in All-Optical Single Quantum-Trajectory Ising Machines
Jacopo Tosca, Marcello Calvanese Strinati, Claudio Conti +1
We investigate the dynamics of multi-mode optical systems driven by two-photon processes and subject to non-local losses, incorporating quantum noise at the Gaussian level. Our fin…
Cavity-modified quantum electron transport in multi-terminal devices and interferometers
Dalin Boriçi, Geva Arwas, Cristiano Ciuti
We theoretically investigate transport affected by cavity-mediated electron hopping in multi-terminal quantum Hall bars, quantum point contacts, and Aharonov-Bohm interferometers.…
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…
Enhanced fractional quantum Hall gaps in a two-dimensional electron gas coupled to a hovering split-ring resonator
Josefine Enkner, Lorenzo Graziotto, Dalin Boriçi +7
The magnetotransport of a high-mobility two-dimensional electron gas coupled to a hovering split-ring resonator with controllable distance is studied in the quantum Hall regime. Th…
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…
