Relativistic quantum oscillators in the global monopole spacetime [PDF]
The European Physical Journal C, 2019 We investigated the effects of the global monopole spacetime on the Dirac and Klein–Gordon relativistic quantum oscillators. In order to do this, we solve the Dirac and Klein–Gordon equations analytically and discuss the influence of this background ...

Anisotropic dyonic black brane and its effects on holographic conductivity
Journal of High Energy Physics, 2017 We investigate a massive gravity theory involving the SL(2, R) symmetry and anisotropy. Due to the SL(2, R) invariance of the equations of motion, the complex con-ductivity of this model transforms covariantly under the SL(2, R) transformation and the ...

Intertwining operator and integrable hierarchies from topological strings
Journal of High Energy Physics, 2021 In [1], Nakatsu and Takasaki have shown that the melting crystal model behind the topological strings vertex provides a tau-function of the KP hierarchy after an appropriate time deformation.

Causal orders, quantum circuits and spacetime: distinguishing between definite and superposed causal orders [PDF]
Quantum, 2019 We study the notion of causal orders for the cases of (classical and quantum) circuits and spacetime events. We show that every circuit can be immersed into a classical spacetime, preserving the compatibility between the two causal structures.

Rindler fluid with weak momentum relaxation
Journal of High Energy Physics, 2018 We realize the weak momentum relaxation in Rindler fluid, which lives on the time-like cutoff surface in an accelerating frame of flat spacetime. The translational invariance is broken by massless scalar fields with weak strength.

Crítica, 2021 Black holes are arguably the most extraordinary physical objects we know in the universe. Despite our thorough knowledge of black hole dynamics and our ability to solve Einstein’s equations in situations of ever increasing complexity, the deeper ...

Hyperboloidal framework for the Kerr spacetime [PDF]
Classical and quantum gravity, 2019 Motivated by the need of a robust geometrical framework for the calculation of long, and highly accurate waveforms for extreme-mass-ratio inspirals, this work presents an extensive study of the hyperboloidal formalism for the Kerr spacetime and the ...

Constraining spacetime nonmetricity with neutron spin rotation in liquid 4He
Physics Letters B, 2017 General spacetime nonmetricity coupled to neutrons is studied. In this context, it is shown that certain nonmetricity components can generate a rotation of the neutron's spin. Available data on this effect obtained from slow-neutron propagation in liquid

Spacetime fluctuations in AdS/CFT [PDF]
Journal of High Energy Physics, 2019 We compute fluctuations in the modular energy of the vacuum associated with a Rindler-wedge in AdS spacetime in the context of AdS/CFT. We discuss the possible effect of these energy fluctuations on the spacetime geometry, and on the traversal time of a ...

International Journal of Modern Physics D, 2018 We propose that the consistent field renormalization of gravity requires a specific Weyl transformation of the metric tensor. As a consequence, proper length and time, as well as energy and momentum, become functions of scale. We estimate the functional form of the field renormalization factor by imposing a minimum resolvable distance scale under an ...
