Minimal formulation of the linear spatial analysis of capillary jets: Validity of the two-mode approach
(American Physical Society, 2018)
A rigorous and complete formulation of the linear evolution of harmonically stimulated capillary jets should include infinitely many spatial modes to account for arbitrary exit conditions [J. Guerrero et al., J. Fluid ...

Phase diagram of the two-fluid Lipkin model: A "butterfly" catastrophe
(American Physical Society, 2016-03-31)
Background: In the past few decades quantum phase transitions have been of great interest in nuclear physics. In this context, two-fluid algebraic models are ideal systems to study how the concept of quantum phase transition ...

Spatial modes in one-dimensional models for capillary jets
(American Physical Society, 2016)
One-dimensional (1D) models are widely employed to simplify the analysis of axisymmetric capillary jets. These models postulate that, for slender deformations of the free surface, the radial profile of the axial velocity can ...

From thermal to excited-state quantum phase transition: The Dicke model
(American Physical Society, 2017-07)
We study the thermodynamics of the full version of the Dicke model, including all the possible values of the total angular momentum j, with both microcanonical and canonical ensembles. We focus on both the excited-state ...

Excited-state quantum phase transitions in a two-fluid Lipkin model
(American Physical Society, 2017-05-30)
Background: Composed systems have become of great interest in the framework of ground-state quantum phase transitions (QPTs) and many of their properties have been studied in detail. However, in these systems, the study ...

A digital quantum simulation of the Agassi model
(Elsevier, 2022)
A digital quantum simulation of the Agassi model from nuclear physics is proposed and analyzed. The proposal is worked out for the case with four different sites. Numerical simulations and analytical estimations are presented ...

Excited-state Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model: Static Aspects
(American Physical Society, 2022)
The basic Lipkin-Meshkov-Glick model displays a second-order ground-state quantum phase transition and an excited-state quantum phase transition (ESQPT). The inclusion of an anharmonic term in the Hamiltonian implies a ...

Excited-state Quantum Phase Transitions in the Anharmonic Lipkin-Meshkov-Glick Model: Dynamical Aspects
(American Physical Society, 2023)
The standard Lipkin-Meshkov-Glick (LMG) model undergoes a second-order ground-state quantum phase transition (QPT) and an excited-state quantum phase transition (ESQPT). The inclusion of an anharmonic term in the LMG ...

Phase diagram of an extended Agassi model
(American Physical Society, 2018)
Background: The Agassi model [D. Agassi, Nucl. Phys. A 116, 49 (1968)NUPABL0375-947410.1016/0375-9474(68)90482-X] is an extension of the Lipkin-Meshkov-Glick (LMG) model [H. J. Lipkin, N. Meshkov, and A. J. Glick, Nucl. ...
