Quantum tunneling and level crossings in the squeeze-driven Kerr oscillator
Miguel A. Prado Reynoso, D. J. Nader, Jorge Chávez-Carlos +6
The quasi-energy spectrum recently measured in experiments with a squeeze-driven superconducting Kerr oscillator showed good agreement with the energy spectrum of its corresponding…
Manifestation of instability in the quasiclassical limit of the spectrum of the quartic double well
D . J. Nader, J. R. Hernandez-Gonzalez, H. Vazquez-Sanchez +1
Within the Bohr's correspondence principle, the quantum theory should reproduce the classical world when . In practice, the discrete energies come close to each other b…
Two- and Three-Particle Complexes with Logarithmic Interaction: Compact Wave Functions for Two-Dimensional Excitons and Trions
J. C. del Valle, J. A. Segura Landa, D. J. Nader
Assuming a logarithmic interaction between constituent particles, compact and locally accurate wave functions that describe bound states of the two-particle neutral and three-parti…
Ultra-Compact accurate wave functions for He-like and Li-like iso-electronic sequences and variational calculus. III. Spin-quartet state of the Lithium sequence
D. J. Nader, J. C. del Valle, J. C. Lopez Vieyra +1

Ground state and polarization of an hydrogen-like atom near a Weyl semimetal
Jorge David Castaño-Yepes, D. J. Nader, A. Martín-Ruiz
In this paper we study the effects of a topological Weyl semimetal (WSM) upon the ground state and polarization of an hydrogen-like atom near its surface. The WSM is assumed to be…
Avoided crossings and dynamical tunneling close to excited-state quantum phase transitions
D. J. Nader, C. A. González-Rodríguez, S. Lerma-Hernández
Using the Wherl entropy, we study the delocalization in phase-space of energy eigenstates in the vicinity of avoided crossing in the Lipkin-Meshkov-Glick model. These avoided cross…

A. V. Turbiner, J. C. Lopez Vieyra, J. C. del Valle +1
As a continuation of Part I \cite{Part-1:2020} (Int. Journal of Quantum Chem. 2021; 121: qua.26586), dedicated to the ground state of He-like and Li-like isoelectronic sequences fo…
The molecule in a strong magnetic field revisited
D. J. Nader, A. V. Turbiner, J. C. López Vieyra
A compact, few-parametric, physically adequate, 3-term variational trial function is used to calculate with high accuracy the energy of the ground state of the hydrogen m…

D. J. Nader, J. C. López Vieyra, A. V. Turbiner
The existence and stability of the linear hydrogenic chain H and H in a strong magnetic field is established. Variational calculations for H and H are carri…
Towards the Theory of the Yukawa Potential
J. C. del Valle, D. J. Nader
Using three different approaches, Perturbation Theory (PT), the Lagrange Mesh Method (Lag-Mesh) and the Variational Method (VM), we study the low-lying states of the Yukawa potenti…
