Title: Multiphoton coherent states for bilayer graphene
Authors: David J. Fern\'andez C. and Dennis I. Mart\'inez-Moreno
Abstract summary: The multiphoton coherent states are derived for electrons in bilayer graphene placed in a constant homogeneous magnetic field. Some physical quantities are calculated for these states, as the Heisenberg uncertainty relation, probability density and mean energy value. In order to study the dynamics of the system the time evolution is explored and the time-correlation function is computed.

Abstract: The multiphoton coherent states, a generalization to coherent sates, are derived for electrons in bilayer graphene placed in a constant homogeneous magnetic field which is orthogonal to the bilayer surface. For that purpose a generalized annihilation operator is constructed in order to determine the multiphoton coherent states as eigenstates of such operator with complex eigenvalue. In addition, some physical quantities are calculated for these states, as the Heisenberg uncertainty relation, probability density and mean energy value. Finally, in order to study the dynamics of the system the time evolution is explored and the time-correlation function is computed.

Polar coherent states in bilayer graphene under a constant uniform magnetic field [0.0]
Hamiltonian describing bilayer graphene subjected to a constant magnetic field to the plane of the bilayer are calculated using polar coordinates. The probability and current densities of the bilayer Hamiltonian have also been calculated in polar coordinates. We also define appropriate coherent states of this system as eigenfunctions, with complex eigenvalues, of a suitable chose operator.

Spreading of a local excitation in a Quantum Hierarchical Model [62.997667081978825]
We study the dynamics of the quantum Dyson hierarchical model in its paramagnetic phase. An initial state made by a local excitation of the paramagnetic ground state is considered. A localization mechanism is found and the excitation remains close to its initial position at arbitrary times.

Formation of robust bound states of interacting microwave photons [148.37607455646454]
One of the hallmarks of interacting systems is the formation of multi-particle bound states. We develop a high fidelity parameterizable fSim gate that implements the periodic quantum circuit of the spin-1/2 XXZ model. By placing microwave photons in adjacent qubit sites, we study the propagation of these excitations and observe their bound nature for up to 5 photons.

Correlated steady states and Raman lasing in continuously pumped and probed atomic ensembles [68.8204255655161]
We consider an ensemble of Alkali atoms that are continuously optically pumped and probed. Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state. We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.

Graphene generalized coherent states [0.0]
We construct the generalized coherent states for an electron in monolayer or bilayer graphene placed in an external magnetic field. At first we define an appropriate set of ladder operators acting on the eigenfunctions for each Hamiltonian. We derive the generalized coherent states through several definitions and analyze the commutation relationship between the ladder operators.

Weyl photons appear when two three-dimensional photonic bands with linear dispersion are degenerated at a single momentum point, labeled as Weyl point. We analyze the dynamics of a single quantum emitter coupled to a Weyl photonic bath as a function of its detuning with respect to the Weyl point.

We revisit the uniaxially strained graphene immersed in a uniform homogeneous magnetic field to describe the time evolution of coherent states build from a semi-classical model. Our results show clearly that the quasi-period of electron coherent states is affected by the uniaxial strain.
