PT-symmetry with a system of three-level atoms
Chao Hang, Guoxiang Huang, Vladimir V. Konotop
We show that a vapor of multilevel atoms driven by far-off resonant laser beams, with possibility of interference of two Raman resonances, is highly efficient for creating parity-t…
Parity-time symmetric optical coupler with birefringent arms
K. Li, D. A. Zezyulin, V. V. Konotop +1
In this work, we propose a PT-symmetric coupler whose arms are birefringent waveguides as a realistic physical model which leads to a so-called quadrimer i.e., a four complex field…
Three-dimensional patchy lattice model for empty fluids
N. G. Almarza, J. M. Tavares, E. G. Noya +1
The phase diagram of a simple model with two patches of type A and ten patches of type B (2A10B) on the face centred cubic lattice has been calculated by simulations and theory. As…
Evading death by vacuum
A. Barroso, P. M. Ferreira, I. P. Ivanov +2
In the Standard Model, the Higgs potential allows only one minimum at tree-level. But the open possibility that there might be two scalar doublets enriches the vacuum structure, al…
Interfacial motion in flexo- and order-electric switching between nematic filled states
Matthew L. Blow, Margarida M. Telo da Gama
We consider a nematic liquid crystal, in coexistence with its isotropic phase, in contact with a substrate patterned with rectangular grooves. In such a system, the nematic phase m…
The nature of the ordered phase of the confined self-assembled rigid rod model
N. G. Almarza, J. M. Tavares, M. M. Telo da Gama
We investigate the nature of the ordered phase and the orientational correlations between adjacent layers of the confined three-dimensional self-assembled rigid rod model, on the c…
MEtop - a generator for single top production via FCNC interactions
Rita Coimbra, António Onofre, Rui Santos +1
We present a generator for single top quark production via flavour-changing neutral currents. The MEtop event generator allows for Next-to-Leading-Order direct top production $pp \…
Charged Higgs bosons in single top production at the LHC
Renato Guedes, Stefano Moretti, Rui Santos
We show that a light charged Higgs boson signal via decay can be established at the Large Hadron Collider (LHC) also in the case of single top production. This process com…
Probing the scalar-pseudoscalar mixing in the 125 GeV Higgs particle with current data
A. Barroso, P. M. Ferreira, Rui Santos +1
LHC has found hints for a Higgs particle of 125 GeV. We investigate the possibility that such a particle is a mixture of scalar and pseudoscalar states. For definiteness, we concen…
Liquid crystals boojum-colloids
M. Tasinkevych, N. M. Silvestre, M. M. Telo da Gama
Colloidal particles dispersed in a liquid crystal lead to distortions of the director field. The distortions are responsible for long-range effective colloidal interactions whose a…
Discrete solitons in coupled active lasing cavities
Jaroslaw E. Prilepsky, Alexey V. Yulin, Magnus Johansson +1
We examine the existence and stability of discrete spatial solitons in coupled nonlinear lasing cavities (waveguide resonators), addressing the case of active defocusing media, whe…
Nonlinear modes in finite-dimensional PT-symmetric systems
D. A. Zezyulin, V. V. Konotop
By rearrangements of waveguide arrays with gain and losses one can simulate transformations among parity-time (PT-) symmetric systems not affecting their pure real linear spectra.…
Nonlinear modes in the harmonic PT-symmetric potential
Dmitry A. Zezyulin, Vladimir V. Konotop
We study the families of nonlinear modes described by the nonlinear Schrödinger equation with the PT-symmetric harmonic potential . The found nonlinear modes display a nu…
New physics contributions to the forward-backward asymmetry at the Tevatron
Sudhansu S. Biswal, Subhadip Mitra, Rui Santos +3
The Tevatron has measured a discrepancy relative to the Standard Model prediction in the forward-backward asymmetry in top quark pair production. This asymmetry grows with the rapi…
Superfluidity of Bose-Einstein condensates in toroidal traps with nonlinear lattices
A. V. Yulin, Yu. V. Bludov, V. V. Konotop +2
Superfluid properties of Bose-Einstein condensates (BEC) in toroidal quasi-one-dimensional traps are investigated in the presence of periodic scattering length modulations along th…
