Non-Hermitian Hamiltonians and Quantum Transport in Multi-Terminal Conductors
Entropy, 2020 We study the transport properties of multi-terminal Hermitian structures within the non-equilibrium Green’s function formalism in a tight-binding approximation.

Nuclear Physics B, 2004 We study the scenario of thermal leptogenesis in which the leptonic asymmetries are resonantly enhanced through the mixing of nearly degenerate heavy Majorana neutrinos that have mass differences comparable to their decay widths. Field-theoretic issues arising from the proper subtraction of real intermediate states from the lepton-number-violating ...

Parity Violation in Neutron Resonances in 107,109Ag [PDF]
, 1999 Parity nonconservation (PNC) was studied in p-wave resonances in Ag by measuring the helicity dependence of the neutron total cross section. Transmission measurements on natural Ag were performed in the energy range 32 to 422 eV with the time-of-flight ...

Resonances in Bianisotropic Layers
IEEE Photonics Journal, 2018 This paper rigorously studies the resonant transmission of electromagnetic waves around embedded trapped modes in bianisotropic films and derives the dispersion relations, the embedded mode condition, and the coupling and tunneling of the evanescent wave

Resonances of rectangular resonators [PDF]
The Journal of the Acoustical Society of America, 1981 We have used variational methods based on the work of Holland and Eernisse to predict the resonant frequencies of rectangular resonators for use in acoustic transducer arrays. We have predicted both the open and short circuited resonances and have compared the theoretical results obtained with a large number of experiments carried out on such ...

A High-Resolution Terahertz Electric Field Sensor Using a Corrugated Liquid Crystal Waveguide
Crystals, 2019 Liquid crystals (LCs) can always reflect variable optical properties in a broad terahertz (THz) band under external electric or magnetic fields. Based on the measurements of these varying properties, we can realize electric and magnetic field sensing ...

Eccentricity Evolution for Planets in Gaseous Disks [PDF]
, 2002 We investigate the hypothesis that interactions between a giant planet and the disk from which it forms promote eccentricity growth. These interactions are concentrated at discrete Lindblad and corotation resonances.

Variational Solutions for Resonances by a Finite-Difference Grid Method
Molecules, 2021 We demonstrate that the finite difference grid method (FDM) can be simply modified to satisfy the variational principle and enable calculations of both real and complex poles of the scattering matrix.

Adiabatic theorems for quantum resonances [PDF]
, 2006 We study the adiabatic time evolution of quantum resonances over time scales which are small compared to the lifetime of the resonances. We consider three typical examples of resonances: The first one is that of shape resonances corresponding, for ...
