Accuracy of second order perturbation theory in the polaron and variational polaron frames by Lee, Chee Kong, Moix, Jeremy, Cao, Jianshu

“…In the study of open quantum systems, the polaron transformation has recently attracted a renewed interest as it offers the possibility to explore the strong system-bath coupling regime. Despite this interest, a clear and unambiguous analysis of the regimes of validity of the polaron transformation is still lacking. …”

Delocalized Davydov D1 Ansatz for the Holstein polaron by Sun, Jin, Duan, Liwei, Zhao, Yang

“…The delocalized D1 Ansatz lowers the ground-state energies at the Brillouin zone boundary significantly compared with the Toyozawa and Global-Local Ansätze in the weak coupling regime, while considerable improvement is demonstrated to have been achieved over the entire Brillouin zone in the strong coupling regime. …”

Fluid-fluid displacement in porous-media microfluidics by Qiu, Yu

“…We first develop a phase-field model to simulate two-phase flow with moving contact lines in the partial wetting regime. We construct a self-consistent formulation of fluid-solid surface energy which allows prescribing arbitrary static contact angles. …”

Modal phase-matched bound states in the continuum for enhancing third harmonic generation of deep ultraviolet emission by Abdelraouf, Omar A. M., Anthur, Aravind P., Wang, Renshaw Xiao, Wang, Qi Jie, Liu, Hong

“…However, NLOs are limited by their bulky size, inadequate transparency at the DUV regime, and stringent phase-matching requirements for harmonic generation. …”

Hawking radiation of extended objects by Johnson, G, March-Russell, J

“…We find that in the low-momentum regime, the power emitted is exponentially suppressed for sufficiently large radiated objects, or sufficiently small black holes, though the temperature of emission is unchanged. …”

Dynamics of localized waves in one-dimensional random potentials : statistical theory of the coherent forward scattering peak by Lee, Kean Loon, Miniatura, Christian, Grémaud, Benoît

“…Going beyond the perturbative regime, we address here the long-time dynamics of the CFS peak in a one-dimensional random system and we relate this novel interference effect to the statistical properties of the eigenfunctions and eigenspectrum of the corresponding random Hamiltonian. …”

Coherently tunable triangular trefoil phaseonium metamaterial by Soci, Cesare, Nguyen, Duc Minh, Ooi, Raymond C. H.

“…We find that, in the metallic regime, the phaseonium metamaterial structure supports extremely large transmission, with optical amplification at large enough intensity of the microwave thanks to strong surface plasmon coupling; while, in the dielectric regime without microwave excitation, the transmission bandwidth can be tuned by varying the control beam intensity. …”

1-in-3 vs. not-all-equal: dichotomy of a broken promise by Ciardo, L, Kozik, M, Krokhin, A, Nakajima, T-V, Živný, S

“…In the present work, we investigate this constraint satisfaction problem in a regime where the promise is weakened from either side by a rainbow-free structure, and establish a complexity dichotomy for the resulting class of computational problems.…”

Natural resources and income inequality in Africa. by Charasz, Pawel.

“…However, the overall effect is dependent upon the political regime and level of population heterogeneity. Whereas natural resources themselves were on average contributing positively to income inequality, greater degree of democracy reduces this effect and greater level of population heterogeneity increases this effect.…”

Effects of resonant tunneling on intrinsic linewidth of quantum cascade lasers by Liu, T., Wang, Q. J.

“…The quantum Langevin analysis for QCLs show that coupling strength and dephasing rate strongly affect the linewidth of THz QCLs in incoherent resonant-tunneling transport regime, but induce insignificant influence for mid-infrared QCLs due to strong coupling.…”
