Dipole symmetry breaking and fractonic Nambu-Goldstone mode
Evangelos Afxonidis, Alessio Caddeo, Carlos Hoyos +1
We introduce a family of quantum field theories for fields carrying monopole and dipole charges. In contrast to previous realizations, fields have quadratic two-derivative kinetic…
Emergent Dipole Gauge Fields and Fractons
Alessio Caddeo, Carlos Hoyos, Daniele Musso
We present a realization of fracton-elasticity duality purely formulated in terms of ordinary gauge fields, encompassing standard elasticity and incommensurate crystals as those de…
Real Quantum Amplitude Estimation
Alberto Manzano, Daniele Musso, Álvaro Leitao
We introduce the Real Quantum Amplitude Estimation (RQAE) algorithm, an extension of Quantum Amplitude Estimation (QAE) which is sensitive to the sign of the amplitude. RQAE is an…
Quantum Arithmetic for Directly Embedded Arrays
Alberto Manzano, Daniele Musso, Álvaro Leitao +4
We describe a general-purpose framework to design quantum algorithms relying upon an efficient handling of arrays. The corner-stone of the framework is the direct embedding of info…
Entropic alternatives to initialization
Daniele Musso
Local entropic loss functions provide a versatile framework to define architecture-aware regularization procedures. Besides the possibility of being anisotropic in the synaptic spa…
Fractons in effective field theories for spontaneously broken translations
Riccardo Argurio, Carlos Hoyos, Daniele Musso +1
We study the concomitant breaking of spatial translations and dilatations in Ginzburg-Landau-like models, where the dynamics responsible for the symmetry breaking is described by a…
Partial local entropy and anisotropy in deep weight spaces
Daniele Musso
We refine a recently-proposed class of local entropic loss functions by restricting the smoothening regularization to only a subset of weights. The new loss functions are referred…
Gapped dilatons in scale invariant superfluids
Riccardo Argurio, Carlos Hoyos, Daniele Musso +1
We study a paradigmatic model in field theory where a global and scale symmetries are jointly and spontaneously broken. At zero density the model has a non-compact flat dire…
Stochastic gradient descent with random learning rate
Daniele Musso
We propose to optimize neural networks with a uniformly-distributed random learning rate. The associated stochastic gradient descent algorithm can be approximated by continuous sto…
Gapless and gapped holographic phonons
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
We study a holographic model where translations are both spontaneously and explicitly broken, leading to the presence of (pseudo)-phonons in the spectrum. The weak explicit breakin…
Holographic fundamental matter in multilayered media
Ulf Gran, Niko Jokela, Daniele Musso +2
We describe a strongly coupled layered system in 3+1 dimensions by means of a top-down D-brane construction. Adjoint matter is encoded in a large- stack of D3-branes, while fu…
Phonon and Shifton from a Real Modulated Scalar
Daniele Musso, Daniel Naegels
We study a massive real scalar field that breaks translation symmetry dynamically. Higher-gradient terms favour modulated configurations and neither finite density nor temperature…
Diffusion and universal relaxation of holographic phonons
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
In phases where translations are spontaneously broken, new gapless degrees of freedom appear in the low energy spectrum (the phonons). At long wavelengths, they couple to small flu…
Universal relaxation in a holographic metallic density wave phase
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
In this work, we uncover a universal relaxation mechanism of pinned density waves, combining Gauge/Gravity duality and effective field theory techniques. Upon breaking translations…
Simplest phonons and pseudo-phonons in field theory
Daniele Musso
We study the emergence of Nambu-Goldstone modes due to broken translation symmetry in field theory. Purely spontaneous breaking yields a massless phonon which develops a mass upon…
DC resistivity of quantum critical, charge density wave states from gauge-gravity duality
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
In contrast to metals with weak disorder, the resistivity of weakly-pinned charge density waves (CDWs) is not controlled by irrelevant processes relaxing momentum. Instead, the lea…
Floquet Scalar Dynamics in Global AdS
Anxo Biasi, Pablo Carracedo, Javier Mas +2
We study periodically driven scalar fields and the resulting geometries with global AdS asymptotics. These solutions describe the strongly coupled dynamics of dual finite-size quan…
Effective holographic theory of charge density waves
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
We use Gauge/Gravity duality to write down an effective low energy holographic theory of charge density waves. We consider a simple gravity model which breaks translations spontane…
Adiabatic pumping solutions in global AdS
Pablo Carracedo, Javier Mas, Daniele Musso +1
We construct a family of very simple stationary solutions to gravity coupled to a massless scalar field in global AdS. They involve a constantly rising source for the scalar field…
A holographic perspective on phonons and pseudo-phonons
Andrea Amoretti, Daniel Arean, Riccardo Argurio +2
We analyze the concomitant spontaneous breaking of translation and conformal symmetries by introducing in a CFT a complex scalar operator that acquires a spatially dependent expect…
Chasing the cuprates with dilatonic dyons
Andrea Amoretti, Matteo Baggioli, Nicodemo Magnoli +1
Magnetic field and momentum dissipation are key ingredients in describing condensed matter systems. We include them in gauge/gravity and systematically explore the bottom-up panora…
Analytic pseudo-Goldstone bosons
Riccardo Argurio, Andrea Marzolla, Andrea Mezzalira +1
We consider the interplay between explicit and spontaneous symmetry breaking in strongly coupled field theories. Some well-known statements, such as the Gell-Mann-Oakes-Renner rela…
A goldstino at the bottom of the cascade
Matteo Bertolini, Daniele Musso, Ioannis Papadimitriou +1
Working within a five-dimensional consistent truncation of type IIB supergravity dimensionally reduced on , we consider supersymmetry breaking solutions with the asymptoti…
Magneto-transport from momentum dissipating holography
Andrea Amoretti, Daniele Musso
We obtain explicit expressions for the thermoelectric transport coefficients of a strongly coupled, planar medium in the presence of an orthogonal magnetic field and momentum-dissi…
