employ this fa... | 2001.08112v1 |
2020-05-29 | Bound states of spin-orbit coupled cold atoms in a Dirac delta-function potential | Dirac delta-function potential is widely studied in quantum mechanics because
it usually can be exactly solved and at the same time is useful in modeling

2022-03-17 | Traveling Wave Form Description for Dirac Field and Its Deduction To Pauli Equation Type Forms in Quantum Mechanics | We derive an equivalent traveling wave form description for Dirac field. In

free-ele... | 0201032v1 |
2004-09-22 | Interaction of magnetic-dipolar modes with microwave-cavity electromagnetic fields | We discuss the problem of magnetic-dipolar oscillations combined with
microwave resonators. The energy density of magnetic-dipolar or magnetostatic
(MS) oscillations in ferrite resonators is not the electromagnetic-wave density
of the energy and not the exchange energy density as well. This fact reveals
very special be... | 0409583v2 |

further simplifi... | 9911123v1 |
2003-07-09 | Time delayed K+ N reactions and exotic baryon resonances | Evidences and hints, both from the theoretical and experimental side, of
exotic baryon resonances with B=S, have been with us for the last thirty years.
The poor status of the general acceptance of these Z* resonances is partly due
to the prejudice against penta-quark baryons and partly due to the opinion that

1998-10-01 | Resonance broadening theory of Farley-Buneman turbulence in the auroral E-region | The conventional theory of resonance broadening for a two-species plasma in a
magnetic field is revised, and applied to an ionospheric turbulence case. The
assumptions made in the conventional theory of resonance broadening have, in
the past, led to replacing the frequency $\omega$ by
$\omega+ik_{\perp}^{2}D^{*}$ in th... | 9810061v1 |
2003-09-05 | Opto-mechanical probes of resonances in amplifying microresonators | We investigate whether the force and torque exerted by light pressure on an
irregularly shaped dielectric resonator allow to detect resonant frequencies,

times larger than i... | 0309035v2 |
2004-02-29 | Interferometric differentiation between resonant Coherent Anti-Stokes Raman Scattering and nonresonant four-wave-mixing processes | A major impediment of using Coherent Anti-Stokes Raman Scattering to identify
biological molecules is that the illumination levels required to produce a
measurable signal often also produce significant nonresonant background from
the medium, especially from water, that is not specific to the resonance being
investigate... | 0403007v1 |
2002-03-25 | Field quantization for open optical cavities | We study the quantum properties of the electromagnetic field in optical

2019-12-10 | Probabilistic motional averaging | In a continuous measurement scheme a spin-1/2 particle can be measured and
simultaneously driven by an external resonant signal. When the driving is weak,
