How small hydrodynamics can go
Matteo Baggioli
Numerous experimental and theoretical results in liquids and plasmas suggest the presence of a critical momentum at which the shear diffusion mode collides with a non-hydrodynamic…
Phase relaxation and pattern formation in holographic gapless charge density waves
Tomas Andrade, Matteo Baggioli, Alexander Krikun
We study the dynamics of spontaneous translation symmetry breaking in holographic models in presence of weak explicit sources. We show that, unlike conventional gapped quantum char…
Detecting Topological Quantum Phase Transitions via the c-Function
Matteo Baggioli, Dimitrios Giataganas
We propose the c-function as a new and accurate probe to detect the location of topological quantum critical points. As a direct application, we consider a holographic model which…
Magnetophonons & type-B Goldstones from Hydrodynamics to Holography
Matteo Baggioli, Sebastian Grieninger, Li Li
We perform a detailed analysis of a large class of effective holographic models with broken translations at finite charge density and magnetic field. We exhaustively discuss the di…
Physics of Phonon-Polaritons in Amorphous Materials
Luigi Casella, Matteo Baggioli, Tatsuya Mori +1
The nature of bosonic excitations in disordered materials has remained elusive due to the difficulties in defining key concepts such as quasi-particles in the presence of disorder.…
