Effective strings and particles interacting in 3D: the Ising model
J. M. Viana Parente Lopes, José Matos, Joao Penedones
We study how a fluctuating domain wall in three dimensions modifies bulk observables in a gapped phase. We introduce an effective interaction between the wall and the lightest bulk…
Effective string theory on a torus: the 3d Ising domain wall
David Lima, J. M. Viana Parente Lopes, Jose Matos +1
We use effective string theory (EST) to describe a toroidal 2d domain wall embedded in a 3d torus. In particular, we compute the free energy of the domain wall in an expansion in i…
Exact nonlinear dynamics of single band metallic systems with dissipation: From optical to dc currents
J. M. Alendouro Pinho, B. Amorim, Yuliy V. Bludov +1
The theory of open quantum systems is one of the most essential tools for the development of quantum technologies. A particular area of interest is in the optical response of solid…
Tunable Magnetic Order in Chiral Coupled Spin Chains
Rafael D. Soares, J. M. Viana Parente Lopes, Hugo Terças
We obtain the ground-state phase diagram of two spin chains consisting in a set two-level systems asymmetrically coupled to an XX chain through a chiral interaction. The interactio…
Environmental Sensitivity of Fabry-Perot Microcavities Induced By Layered Graphene-Dielectric Hybrid Coatings
Rui Peixoto, J. P. Santos Pires, Catarina S. Monteiro +5
We propose a fiber-based environmental sensor that exploits the reflection phase shift tunability provided by the use of layered coatings composed of dielectric slabs spaced by con…
Second order divergence in the third order DC response of a cold semiconductor
G. B. Ventura, D. J. Passos, J. M. Viana Parente Lopes +1
In this work, we present the analytical expression for the second order divergence in the third order DC response of a cold semiconductor, which can be probed by different electric…
