Plasmons in twisted bilayer graphene across dispersive and flat bands
Antonio Palamara, Michele Pisarra, Antonello Sindona
The dynamical dielectric response of twisted bilayer graphene is explored in large-angle dispersive-band and small-angle quasi-flat-band regimes using time-dependent density-functi…
The Hidden Cost of Alloying: Disorder-Driven Transport Collapse in TMDs
Michele Pisarra, Clara Rebanal, Enrique Arévalo Rodríguez +19
Alloying in two dimensional semiconductors is widely used to tune bandgaps, yet its implications for charge and energy transport remain poorly understood. Here, we investigate MoS2…
Revealing Many-Body Phases at finite temperatures through Quantum Coherence Distribution
Antonio Palamara, Nicola Lo Gullo, Antonello Sindona +1
We introduce a diagnostic framework based on the full probability distribution of quantum coherence to probe single-particle and many-body phases at finite temperature. We first ap…
Full Quantum Work Statistics for Non-Homogeneous Many-Body Systems
Antonio Palamara, Francesco Plastina, Antonello Sindona +1
The nonequilibrium thermodynamics of interacting quantum many-body systems is investigated within the framework of thermal time-dependent density functional theory using a generali…
Thermal density functional theory approach to quantum thermodynamics
Antonio Palamara, Francesco Plastina, Antonello Sindona +1
Understanding the thermodynamic properties of many-body quantum systems and their emergence from microscopic laws is a topic of great significance due to its profound fundamental i…
Magic distances in twisted bilayer graphene
Antonio Palamara, Michele Pisarra, Antonello Sindona
Twisted bilayer graphene exhibits isolated, relatively flat electronic bands near charge neutrality when the interlayer rotation is tuned to specific magic angles. These small misa…
Engineering a Spin-Orbit Bandgap in Graphene-Tellurium Heterostructures
B. Muñiz Cano, D. Pacilè, M. G. Cuxart +13
Intensive research has focused on harnessing the potential of graphene for electronic, optoelectronic, and spintronic devices by generating a bandgap at the Dirac point and enhanci…
Interband -like plasmon in silicene grown on silver
A. Sindona, A. Cupolillo, F. Alessandro +4
Silicene, the two-dimensional allotrope of silicon, is predicted to exist in a low-buckled honeycomb lattice, characterized by semimetallic electronic bands with graphenelike energ…
Plasmon properties and hybridization effects in Silicene
C. Vacacela Gomez, M. Pisarra, M. Gravina +2
The plasmonic character of monolayer silicene is investigated by time-dependent density functional theory in the random phase approximation. The energy-loss function of the system…
Plasmon modes of graphene nanoribbons with periodic planar arrangements
Cristian Vacacela Gomes, Michele Pisarra, Mario Gravina +2
Among their amazing properties, graphene and related low-dimensional materials show quantized charge-density fluctuations--known as plasmons--when exposed to photons or electrons o…
Spatial dispersion effects upon local excitation of extrinsic plasmons in a graphene micro-disk
Davide Mencarelli, Stefano Bellucci, Antonello Sindona +1
Excitation of surface plasmon waves in extrinsic graphene is studied using a full-wave electromagnetic field solver as analysis engine. Particular emphasis is placed on the role pl…
Decoherence in a fermion environment: Non-Markovianity and Orthogonality Catastrophe
F. Plastina, A. Sindona, J. Goold +2
We analyze the non-Markovian character of the dynamics of an open two-level atom interacting with a gas of ultra-cold fermions. In particular, we discuss the connection between the…
Acoustic plasmons in extrinsic free-standing graphene
M. Pisarra, A. Sindona, P. Riccardi +2
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers co…
