We propose an exact model of anyon ground states including higher Landau levels, and use it to obtain fractionally quantized Hall at filling fractions $\nu=p/(p(m-1)+1)$ with $m$ odd, from integer $\nu=p$ through adiabatic localization magnetic flux. For appropriately chosen two-body potential interactions, the energy gap remains intact during process. The construction hence establishes existen...

Abstract The paper presents a split-level sinusoidal power supply clock generator circuit for Two-Phase Adiabatic Static CMOS Logic circuit (2PASCL). The driving of adiabatic logic requires adiabatic controlled sources of voltage. We study the clock voltage generator circuit using SPICE simulation and investigate the most suitable scheme and highest energy efficiency for the energy recovery pow...

The integral relations formalism introduced in [P. Barletta et al., Phys. Rev. Lett. 103, 090402 (2009); C. Romero-Redondo et al., Phys. Rev. A 83, 022705 (2011)] and designed to describe 1 +N reactions is extended here to collision energies above the threshold for the target breakup. These two relations are completely general, and in this work they are used together with the adiabatic expansio...

The coupled transfer of electrons and protons is a central feature of biological and molecular catalysis, yet fundamental aspects of these reactions remain poorly understood. In this study, we extend the ring polymer molecular dynamics (RPMD) method to enable direct simulation of proton-coupled electron transfer (PCET) reactions across a wide range of physically relevant regimes. In a system-ba...

We review the effects of excited-state quantum phase transitions (ESQPTs) in interacting many-body systems with finite numbers collective degrees freedom. classify typical ESQPT signatures spectra energy eigenstates respect to underlying classical dynamics and outline a variety which they occur. describe thermodynamic dynamic consequences ESQPTs, like those microcanonical thermodynamics, quench...

We map the general relativistic two-body problem onto that of a test particle moving in an effective external metric. This effective-one-body approach defines, in a non-perturbative manner, the late dynamical evolution of a coalescing binary system of compact objects. The transition from the adiabatic inspiral, driven by gravitational radiation damping, to an unstable plunge, induced by strong ...

The root mean square matter radii of halo nuclei provide a basic measure in constructing, constraining, and assessing theoretical models of halo structures. We consider corrections to static density ~optical limit! Glauber model calculations of reaction cross sections of such nuclei at high energy giving careful consideration to their intrinsic few-body structure and the adiabatic nature of the...

Abstract Quantum many-body phases offer unique properties and emergent phenomena, making them an active area of research. A promising approach for their experimental realization in model systems is to adiabatically follow the ground state a quantum Hamiltonian from product isolated particles one that strongly-correlated. Such protocols are relevant also more broadly coherent annealing adiabatic...

Coupling the dark matter (DM) and baryonic components in galaxies via dynamical friction (by allowing the latter to be clumpy) leads to energy input into the DM. The resulting expanding tendency in the DM component overcomes the competing effect of adiabatic contraction, resulting from the shrinking gas component, and leads to a nearly constant density core. The baryonic mass inflow also leads ...
