Floquet Topological Frequency-Converting Amplifier
Adrian Parra-Rodriguez, Miguel Clavero-Rubio, Philippe Gigon +3
We introduce a driven-dissipative Floquet model in which a single harmonic oscillator, with both frequency and decay rate modulated, realizes a non-Hermitian synthetic lattice with…
Decoherence-free subspaces in the noisy dynamics of discrete-step quantum walks in a photonic lattice
Rajesh Asapanna, Clément Hainaut, Alberto Amo +1
We study the noisy dynamics of periodically driven, discrete-step quantum walks in a one-dimensional photonic lattice. We find that in the bulk, temporal noise that is constant wit…
Observation of extrinsic topological phases in Floquet photonic lattices
Rajesh Asapanna, Rabih El Sokhen, Albert F. Adiyatullin +4
Discrete-step walks describe the dynamics of particles in a lattice subject to hopping or splitting events at discrete times. Despite being of primordial interest to the physics of…
Topological Josephson parametric amplifier array: A proposal for directional, broadband, and low-noise amplification
Tomás Ramos, Álvaro Gómez-León, Juan José García-Ripoll +2
Low-noise microwave amplifiers are crucial for detecting weak signals in fields such as quantum technology and radio astronomy. However, designing an ideal amplifier is challenging…
A perspective on scaling up quantum computation with molecular spins
S. Carretta, D. Zueco, A. Chiesa +2
Artificial magnetic molecules can contribute to progressing towards large scale quantum computation by: a) integrating multiple quantum resources and b) reducing the computational…
Correlation effects in spin models in the presence of a spin bath
Álvaro Gómez-León, Tim Cox, Philip Stamp
We analyze the effect of a bath of spins interacting with a spin system in terms of the equation of motion technique. We show that this formalism can be used with general spin syst…
Interplay between long range hopping and disorder in topological systems
Beatriz Pérez-González, Miguel Bello, Álvaro Gómez-León +1
We extend the standard SSH model to include long range hopping and disorder, and study how the electronic and topological properties are affected. We show that long range hopping c…
SSH model with long-range hoppings: topology, driving and disorder
Beatriz Pérez-González, Miguel Bello, Álvaro Gómez-León +1
The Su-Schrieffer-Heeger (SSH) model describes a finite one-dimensional dimer lattice with first-neighbour hoppings populated by non-interacting electrons. In this work we study a…
Hierarchy of correlations for the Ising model in the Majorana representation
Álvaro Gómez-León
We study the quantum Ising model in D dimensions with the equation of motion technique, in combination with the Majorana representation for spins. The decoupling scheme used for th…
Hierarchy of correlations: Application to Green's functions and interacting topological phases
Álvaro Gómez-León
We study the many-body physics of different quantum systems using a hierarchy of correlations, which corresponds to a generalization of the hierarchy. The decouplin…
Floquet engineering of long-range p-wave superconductivity
Mónica Benito, Álvaro Gómez-León, Victor Bastidas +2
Floquet Majorana Fermions appear as steady states at the boundary of time-periodic topological phases of matter. In this work, we theoretically study the main features of these exo…
Floquet Fractional Chern Insulator in Doped Graphene
Adolfo G. Grushin, Álvaro Gómez-León, Titus Neupert
Fractional Chern insulators are theoretically predicted states of electronic matter with emergent topological order. They exhibit the same universal properties as the fractional qu…

Álvaro Gómez-León, Gloria Platero
We analyze electron dynamics and topological properties of open double quantum dots (DQDs) driven by circularly polarized ac-magnetic fields. In particular we focus on the system s…
Topological phases in adiabatic and nonadiabatic driven systems
Álvaro Gómez-León, Gloria Platero
In this work we study the geometrical and topological properties of non-equilibrium quantum systems driven by ac fields. We consider two tunnel coupled spin qubits driven by either…
