Anomalous Hall viscosity of altermagnets
Iksu Jang, Rui Aquino, Jörg Schmalian +1
We show that the phonon Hall viscosity at zero magnetic field is a natural probe of altermagnetism. First, we demonstrate that the finite elements of the Hall viscosity tensor unam…
Effective-medium theory for elastic systems with correlated disorder
Jorge M. Escobar-Agudelo, Rui Aquino, Danilo B. Liarte
Correlated structures are intimately connected to intriguing phenomena exhibited by a variety of disordered systems such as soft colloidal gels, bio-polymer networks and colloidal…
Oscillators with imaginary coupling: spectral functions in quantum mechanics and quantum field theory
Bruno W. Mintz, Itai Y. Pinheiro, Rui Aquino
The axioms of Quantum Mechanics require that the hamiltonian of any closed system is self-adjoint, so that energy levels are real and time evolution preserves probability. On the o…
Effects of kinetic energy on heat fluctuations of passive and active overdamped driven particles
Pedro V. Paraguassú, Rui Aquino, Pablo de Castro
To describe the spatial trajectory of an overdamped Brownian particle, inertial effects can be neglected. Yet, at the energetic level of stochastic thermodynamics, changes in kinet…
Laser induced -symmetry breaking in the fluctuations of electronic fluids
Rui Aquino, Nathan O. Silvano, Daniel G. Barci
Electronic fluids can display exciting dynamical properties. In particular, due to Landau damping, the collective modes spectrum of an electronic system with multipolar interaction…
Critical and non critical non-Hermitian topological phase transitions in one dimensional chains
Rui Aquino, Nei Lopes, Daniel G. Barci
In this work we investigate non-Hermitian topological phase transitions using real-space edge states as a paradigmatic tool. We focus on the simplest non-Hermitian variant of the S…
Effects of the kinetic energy in heat for overdamped systems
Pedro V. Paraguassú, Rui Aquino, Lucianno Defaveri +1
In the derivation of the thermodynamics of overdamped systems, one ignores the kinetic energy contribution, since the velocity is a slow variable. In this paper, we show that the k…
Probing Fermi liquid exceptional points through AC conductivity
Rui Aquino, Daniel G. Barci
Exceptional points, which are topological non-Hermitian degeneracies, show up in the collective mode spectrum of Fermi Liquids with high angular momentum interactions. In this pape…
The Heat Distribution of the Underdamped Langevin Equation
Pedro V. Paraguassú, Rui Aquino, Welles A. M. Morgado
In Stochastic Thermodynamics, heat is a random variable with a probability distribution associated. Studies of the distribution of heat are mostly in the overdamped regime and in o…
Exceptional points in Fermi liquids with quadrupolar interactions
Rui Aquino, Daniel G. Barci
We show the existence of non-Hermitian degeneracies, known as exceptional points, in the collective mode spectrum of Fermi liquids with quadrupolar interactions. Through a careful…
Two-dimensional Fermi liquid dynamics with density and quadrupolar interactions
Rui Aquino, Daniel G. Barci
We consider a Fermi liquid model with density-density as well as quadrupolar forward scattering interactions parametrized by the Landau parameters and . Using bosonizati…
