Collective modes of the superconducting condensate [PDF]

open access: yes, 2023
When a continuous symmetry is spontaneously broken, collective modes emerge. Usually, their spectrum is dominated by the low-energy physics of massless Goldstone modes. Superconductors, that break U(1) symmetry, are different.

Collection collective: collection of contemporary art

open access: yes, 2018
Collection Collective was initiated as a speculative curatorial proposal wherein a group of artists, designers, architects, lawyers, economists, and cultural producers were invited to reflect on the possibility of constructing a contemporary art ...

On the stability of Yang-Mills vacuum

open access: yesPhysics Letters B, 2023
The (anti)self-dual covariantly constant vacuum fields have positive/stable and infinitely many zero modes, so called Leutwyller chromons. A regularisation method is suggested that allows to sum the contribution of the zero modes and to obtain the ...

Plasmonic Physics of 2D Crystalline Materials

open access: yesApplied Sciences, 2018
Collective modes of doped two-dimensional crystalline materials, namely graphene, MoS 2 and phosphorene, both monolayer and bilayer structures, are explored using the density functional theory simulations together with the random phase ...

Agent Based Modelling and Simulation of Pedestrian Crowds in Panic Situations [PDF]

open access: yes, 2020
The increasing occurrence of panic stampedes during mass events has motivated studying the impact of panic on crowd dynamics. Understanding the collective behaviors of panic stampedes is essential to reducing the risk of deadly crowd disasters.

Modes of information flow in collective cohesion [PDF]

open access: yes, 2022
Pairwise interactions are fundamental drivers of collective behavior-responsible for group cohesion. The abiding question is how each individual influences the collective.

Wavevector- and frequency-dependent shear viscosity of water: the modified collective mode approach and molecular dynamics calculations

open access: yesCondensed Matter Physics, 2005
The transverse momentum time autocorrelation functions and wavevector- and frequency-dependent shear viscosity are calculated for an interaction site model of water using a modified collective mode approach and molecular dynamics simulations.

On the mechanical interplay between intra- and inter-synchronization during collective cell migration : a numerical investigation [PDF]

open access: yes, 2013
Collective cell migration is a fundamental process that takes place during several biological phenomena such as embryogenesis, immunity response, and tumorogenesis, but the mechanisms that regulate it are still unclear.
