Collective excitations in 2D materials [PDF]
Nature Reviews Physics, 2020 Research on 2D materials has been one of the fastest-growing fields in condensed matter physics and materials science in the past 10 years. The low dimensionality and strong correlations of 2D systems give rise to electronic and structural properties, in the form of collective excitations, that do not have counterparts in ordinary 3D materials used in ...

Collective excitations in jammed states: ultrafast defect propagation and finite-size scaling
New Journal of Physics, 2022 In crowded systems, particle currents can be mediated by propagating collective excitations which are generated as rare events, are localized, and have a finite lifetime.

Excited states of quantum many-body interacting systems: A variational coupled-cluster description [PDF]
, 2007 We extend recently proposed variational coupled-cluster method to describe excitation states of quantum many-body interacting systems. We discuss, in general terms, both quasiparticle excitations and quasiparticle-density-wave excitations (collective ...

Beliaev damping of the Goldstone mode in atomic Fermi superfluids [PDF]
, 2015 Beliaev damping in a superfluid is the decay of a collective excitation into two lower frequency collective excitations; it represents the only decay mode for a bosonic collective excitation in a superfluid at T = 0. The standard treatment for this decay

Collective excitations of nuclear matter [PDF]
Annals of Physics, 1959 Abstract A study of the collective motions of nuclear matter has been made. We first give a purely classical macroscopic description of hydrodynamic waves in nuclear matter, and suggest some experimental consequences of their excitation. Next a quantum mechanical study of the collective eigenstates of nuclear matter is taken up. The starting point of

Quasiparticle theory of collective electron excitations in graphene [PDF]
APL Electronic DevicesIn this paper, we develop a new approach for analyzing collective quantum excitations in graphene, based on the quantum multistream model. We explore a range of phenomena, including the energy band structure of collective modes, linear and nonlinear ...

New Journal of Physics, 2012 Collective excitations in nano-plasmas are described by dynamical bi-local auto-correlation functions. These excitations, which are related to the plasmon excitations in bulk plasmas, arise in the classical as well as the quantum regime.

Collective Excitations of 14N and 10B Nuclei [PDF]
Kirkuk Journal of Science, 2016 The nuclear structure of 14N and 10B nuclei are studied in framework two collective excitation approximations. The first approximation is hole-hole Tamm-Dancoff Approximation (hh TDA) and the second is hole-hole Random Phase Approximation (hh RPA).
