Bosonic quantum devices offer a novel approach to realize quantum computations, where
the quantum two-level system (qubit) is replaced with the quantum (an) harmonic oscillator …

The second edition of an established graduate text, this book complements the material for a
typical advanced graduate course in quantum mechanics by showing how the underlying …

We analyze shape phase transitions in two-dimensional algebraic models. We apply our
analysis to linear-to-bent transitions in molecules and point out what observables are …

Signatures of quantum phase transitions (QPTs) and excited state quantum phase
transitions (ESQPTs) in the bending motion of eight XYZ triatomic molecules (HCN, HNC …

The hydrogen atom perturbed by sufficiently small homogeneous static electric and
magnetic fields of arbitrary mutual alignment is a specific perturbation of the Kepler system …

Fulminic acid (HCNO) played a critical role in the early development of organic chemistry,
and chemists have sought to discern the structure and characteristics of this molecule and its …

The concepts of quantum phase transition (QPT) and excited state quantum phase transition
(ESQPT) are applied to the study of bending motion in non-rigid molecules. Two key …

We present an extension of the Hamiltonian of the two dimensional limit of the vibron model
to encompass all possible interactions up to four-body operators. We apply this Hamiltonian …

The rotational spectrum of cyanic acid, HOCN, has been detected in the centimeter-wave
band in a molecular beam by Fourier transform microwave spectroscopy and in the …

The efficiency and insight of global, polyad-based modeling in overtone spectroscopy and
dynamics is demonstrated. Both vibration and vibration–rotation polyads are considered …
