In the standard Landau-Zener-St\"uckelberg-Majorana (LZSM) problem, bias sweep rate and gap are both time independent fully characterize LZSM problem. We consider nonlinear in which at least one of two characteristic parameters varies as system traverses avoided-crossing region. This situation results what could be thought a more accurate description any realistic compared with idealized linear...

The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...

We investigate the influence of temperature and dissipation on the Landau–Zener transition probability in circuit QED. Dissipation is modelled by coupling the transmission line to a bath of harmonic oscillators, and the reduced density operator is treated within Bloch–Redfield theory. A phase-space representation allows an efficient numerical implementation of the resulting master equation. It ...

Internal friction (I.F.) and modulus measurements have been carried out as a function of temperature in order to study the Li mobility in an A1 8.1 at% Li 0.03 at% Zr alloy. The results show that the sequence of 6' and 6 precipitation can be followed through the evolution of the internal friction spectra. Two peaks appear in the internal friction spectrum. The low temperature peak Pz (450 K), h...

– We consider the inverse Landau-Zener problem which consists in finding the energy-sweep functions W (t) ≡ ε1(t) − ε2(t) resulting in the required time dependences of the level populations for a two-level system crossing the resonance one or more times during the sweep. We find sweep functions of particular forms that let manipulate the system in a required way, including complete switching fr...

We investigate the Landau-Zener tunneling (LZT) of a self-interacting two-level system in which coupling between levels is nonreciprocal. In such non-Hermitian system, when energy bias two adjusted very slowly, i.e., adiabatic limit, we find that quantum state can still closely follow eigenstate solution until it encounters exceptional points (EPs) at eigenvalues and their corresponding eigenve...
