Dynamical evolution of spinodal decomposition in holographic superfluids
Xin Zhao, Zi-Qiang Zhao, Zhang-Yu Nie +3
We study the nonlinear dynamical evolution of spinodal decomposition in a first-order superfluid phase transition using a simple holographic model in the probe limit. We first conf…
Stringlet Excitation Model of the Boson Peak
Cunyuan Jiang, Matteo Baggioli, Jack F. Douglas
The boson peak (BP), a low-energy excess in the vibrational density of states over the Debye contribution, is often identified as a characteristic of amorphous solid materials. Des…
Correlation between optical phonon softening and superconducting in YBaCuO within -wave Eliashberg theory
Cunyuan Jiang, Giovanni A. Ummarino, Matteo Baggioli +2
We provide a mathematical description, based on d-wave Eliashberg theory, of the strong correlation between the experimentally observed softening of Raman modes associated with in-…
Engineering flat bands in twisted-bilayer graphene away from the magic angle with chiral optical cavities
Cunyuan Jiang, Matteo Baggioli, Qing-Dong Jiang
Twisted bilayer graphene (TBG) is a recently discovered two-dimensional superlattice structure which exhibits strongly-correlated quantum many-body physics, including strange metal…
Topological defects reveal the plasticity of glasses
Matteo Baggioli
Mixing theoretical topological structures with cutting-edge simulation methods, a recent study in Nature Communications has finally confirmed the existence of topological defects i…
A fresh look at the vibrational and thermodynamic properties of liquids within the soft potential model
Haichen Xu, Matteo Baggioli, Tom Keyes
Contrary to the case of solids and gases, where Debye theory and kinetic theory offer a good description for most of the physical properties, a complete theoretical understanding o…
Constrains on s and d components of electron boson coupling constants in one band d wave Eliashberg theory for high Tc superconductors
Giovanni Alberto Ummarino
The phenomenology of overdoped high Tc superconductors can be described by a one band d wave Eliashberg theory where the mechanism of superconducting coupling is mediated by antife…
U(1) quasi-hydrodynamics: Schwinger-Keldysh effective field theory and holography
Matteo Baggioli, Yanyan Bu, Vaios Ziogas
We study the quasi-hydrodynamics of a system with a softly broken global symmetry using effective field theory (EFT) and holographic methods. In the gravity side, we conside…
Holographic dissipative space-time supersolids
Peng Yang, Matteo Baggioli, Zi Cai +2
Driving a system out of equilibrium enriches the paradigm of spontaneous symmetry breaking, which could then take place not only in space but also in time. The interplay between te…
Collective dynamics and the Anderson-Higgs mechanism in a bona fide holographic superconductor
Hyun-Sik Jeong, Matteo Baggioli, Keun-Young Kim +1
The holographic superconductor is one of the most popular models in the context of applied holography. Despite what its name suggests, it does not describe a superconductor. On the…
Anharmonic theory of superconductivity and its applications to emerging quantum materials
Chandan Setty, Matteo Baggioli, Alessio Zaccone
The role of anharmonicity on superconductivity has often been disregarded in the past. Recently, it has been recognized that anharmonic decoherence could play a fundamental role in…
