Understanding of the Switching Mechanism of a Pt/Ni-Doped SrTiO3 Junction via Current–Voltage and Capacitance–Voltage Measurements

“…Once again the deviations are larger for low Z and tends to diminish with an increase in Z. As pointed out in several recent works for the hollow Rydberg series of Li including the present formalism [24][25][26]51], these resonances are also expected to be highly entangled to each other, making their precise theoretical calculation as well as experimental observation significantly complicated. However, as expected, the separation between the successive members within a resonance series increases as Z goes up.…”

“…In a later work, Safronova and Senashenko [16] performed a detailed and systematic study on the n = 2 intrashell states of the Li-isoelectronic series employing a 1/Z expansion approach for a wide range of Z. Thereafter, a multitude of theoretical methodologies have been proposed which provide results in fairly good agreement with the experimental works, namely, the joint saddle point (SP) and complex coordinate rotation (CCR) method [17][18][19][20], the state-specific theory [21,22], the space partition and stabilization approach [23], the R-matrix theory along with many of its variants [24,25], the truncated diagonalization method (TDM) [26][27][28], the hyperspherical coordinate formalism [29,30], etc.…”

Floquet control of quantum dissipation in spin chains

“…First, our decoherence inhibition mechanism is more robust to the imperfect fluctuation of the driving parameters than the decoupling mechanism revealed in Ref. [30,31], where the decoupling is achieved only in certain single values of the driving parameters. To see this, we resort to the same approximate method as in Refs.…”

“…There are several methods in the literature to explore the effects of periodic driving on quantum systems. For example, via neglecting the coupling between different temporal subspaces of the Floquet eigenequation (7) in the high-frequency driving condition, it was shown that the periodic driving can induce the suppressed tunneling of a quantum particle, a phenomenon called coherent destruction of tunneling [25][26][27], and the decoupling between open system and its environment [30,31]. It was also revealed that, via introducing the first-Markovian approximation to Eq.…”

“…Many efforts have been devoted to explore non-trivial effects induced by periodic driving on physical systems. It has been proven to play profound role not only in controlling single-quantum-state of microscopic systems [25][26][27][28][29][30][31][32] and implementing geometric phase gates in quantum computation [33,34], but also in generating novel states of matter absent in the original static system [35][36][37][38][39][40][41][42]. Different from static systems, periodically driven systems have no stationary states because the energy is not conserved.…”
