Topological phase transitions via attosecond x-ray absorption spectroscopy
Juan F. P. Mosquera, Giovanni Cistaro, Mikhail Malakhov +6
We present a numerical experiment that demonstrates the possibility to capture topological phase transitions via an x-ray absorption spectroscopy scheme. We consider a Chern insula…
Near-horizon aspects of acceleration radiation by free fall of an atom into a black hole
H. E. Camblong, A. Chakraborty, C. R. Ordonez
A two-level atom freely falling towards a Schwarzschild black hole was recently shown to detect radiation in the Boulware vacuum in an insightful paper [M. O. Scully et al., Proc.…
Virial Expansion for a Three-Component Fermi Gas in One Dimension: The Quantum Anomaly Correspondence
Jeff Maki, Carlos R. Ordóñez
In this paper we explore the transport properties of three-component Fermi gases confined to one spatial dimension, interacting via a three-body interaction, in the high temperatur…
Spectral density, Levinson's theorem, and the extra term in the second virial coefficient for 1D delta-function potential
H. E. Camblong, A. Chakraborty, W. S. Daza +3
In contrast with the 3D result, the Beth-Uhlenbeck (BU) formula in 1D contains an extra -1/2 term. The origin of this -1/2 term is explained using a spectral density approach. To b…
A Quantum Field-Theoretical Perspective on Scale Anomalies in 1D systems with Three-Body Interactions
Wilder S. Daza, Joaquín E. Drut, Chris L. Lin +1
We analyze, from a canonical quantum field theory perspective, the problem of one-dimensional particles with three-body attractive interactions, which was recently shown to exhibit…
On the gauge action of a Leavitt path algebra
María Guadalupe Corrales García, Dolores Martín Barquero, Cándido Martín González
We introduce a revised notion of gauge action in relation with Leavitt path algebras. This notion is based on group schemes and captures the full information of the grading on the…
