Searching for Axions on a Higher Note: Third-Harmonic Generation from Colliding High-Intensity Laser Beams
Ashis Paul, Leone di Mauro Villari, Davide Tedeschi +3
We propose a new laboratory strategy to generate and detect axion-like particles via third-harmonic generation induced by two non-collinear, polarised high-intensity laser beams of…
Scaling native entanglement generation in layered semiconductors with quasi-phase matching
Benjamin Braun, Andrea Alessandrini, Josip Bajo +10
Efficient generation of entangled photons typically relies on spontaneous parametric down-conversion (SPDC) in phase-matched macroscopic nonlinear media. However, generating entang…
Enhanced third harmonic response of the PtTe transition metal dichalcogenide
Leone Di Mauro Villari, Simone Grillo, Olivia Pulci +3
We investigate the third harmonic response of platinum ditelluride (PtTe), a Dirac semimetal belonging to the transition metal dichalcogenides class. Due to its topological pro…
The Fracton quantum gas
Leone Di Mauro Villari, Alesssandro Principi
Starting from a simple dipole-conserving Hamiltonian model, after introducing a proper quantisation framework, we construct the linear-response theory of a fracton quantum gas. We…
Grassmann phase space dynamics of strongly-correlated fermion
Hassan Al-Hamzawi, Alessandro Principi, Leone Di Mauro Villari
We discuss the numerical implementation of two related representations of fermionic density matrices which have been introduced in Annals of Physics 370, 12 (2016). In both of them…
2D Weyl Materials in the Presence of Constant Magnetic Fields
Yaraslau Tamashevich, Leone Di Mauro Villari, Marco Ornigotti
In this work we investigate the effect of a constant external, or artificial, magnetic field on the nonlinear response of 2D Weyl materials. We calculate the Landau Levels for tilt…
Optotwistronic of bilayer graphene
Leone Di Mauro Villari, Alessandro Principi
We present a study of the nonlinear optical response of twisted bilayer graphene. We discuss the contribution of the Berry phase to the non-linearity when inversion symmetry is bro…
Nonlinear optical response of Type-II Weyl fermions in two dimensions
Yaraslau Tamashevich, Leone Di Mauro Villari, Marco Ornigotti
We present a theoretical model to study the nonlinear optical response of materials with a low-energy spectrum characterised by strongly tilted, type-II, Weyl cones in two dimensio…
Sine-Gordon soliton as a model for Hawking radiation of moving black holes and quantum soliton evaporation
Leone Di Mauro Villari, Giulia Marcucci, Maria Chiara Braidotti +1
The intriguing connection between black holes' evaporation and physics of solitons is opening novel roads to finding observable phenomena. It is known from the inverse scattering t…
Quantum Soliton Evaporation
Leone Di Mauro Villari, Ewan M. Wright, Fabio Biancalana +1
We have very little experience of the quantum dynamics of the ubiquitous nonlinear waves. Observed phenomena in high energy physics are perturbations to linear waves, and classical…
Squeezing of X waves with orbital angular momentum
Marco Ornigotti, Leone di Mauro Villari, Alexander Szameit +1
Multi-level quantum protocols may potentially supersede standard quantum optical polarization-encoded protocols in terms of amount of information transmission and security. However…
