Abstract Measurement and estimation of parameters are essential for science engineering, where one the main quests is to find systematic schemes that can achieve high precision. While conventional quantum parameter focus on optimization probe states measurements, it has been recently realized control during evolution significantly improve The identification optimal controls, however, often computationally demanding, as typically controls depend value which then needs be re-calculated after...

Quantum control can be employed in quantum metrology to improve the precision limit for estimation of unknown parameters. The optimal control, however, typically depends on actual values parameters and thus needs designed adaptively with updated estimations those Traditional methods, such as gradient ascent pulse engineering (GRAPE), need rerun each new set encountered, making optimization costly, especially when many are involved. Here we study generalizability namely, controls that...

We perform the projector quantum Monte Carlo (QMC) simulation to study trion formation and phase transition in half filled attractive SU(3) Hubbard model on a honeycomb lattice. With increasing interaction, our simulations demonstrate continuous from semimetal charge-density wave (CDW) at critical coupling ${U}_{c}/t=\ensuremath{-}1.52(2)$. The exponents $\ensuremath{\nu}=0.82(3)$ $\ensuremath{\eta}=0.58(4)$ determined by QMC remarkably disagree with those of $N=3$ chiral Ising universality...

We employ the large-scale quantum Monte Carlo simulations to investigate Mott-insulating states of half-filled SU(4) Hubbard model on square lattice with a staggered-flux pattern. The noninteracting band structure that evolves from nested Fermi surface at zero flux isotropic Dirac cones $\ensuremath{\pi}$ flux, exhibits anisotropic as varies in between. Our show transitions between three phases semimetal, antiferromagnet, and valence-bond solid. A direct continuous transition...

Orthodontic tooth movement is a complex biological process of altered soft and hard tissue remodeling as result external forces. In order to understand these processes, it critical study the periodontal tissues within their 3D context therefore minimize any sectioning artefacts. Mouse models are often utilized in developmental structural biology, well biomechanics due small size, high metabolic rate, genetics ease handling. principle this also makes them excellent for dental related studies....

The title compound, C(10)H(9)NO(2)Se, crystallizes as flat molecules linked by selenium-oxygen interactions [Se.O = 3.189 (4) A] into a linear chain along the axis of triclinic cell. bond dimensions that are derived from ab initio geometry optimization calculations similar to those determined diffraction measurements.

We employ the determinant quantum Monte Carlo method to study finite-temperature properties of half-filled attractive $\mathrm{SU}(3)$ Hubbard model on a honeycomb lattice. calculate phase diagram in which boundary separates disordered and charge density wave (CDW) transition temperature ${T}_{\text{tr}}(|U|)$ varies nonmonotonically with interaction $|U|$. As $|U|$ increases at constant $T<\text{max}({T}_{\text{tr}}(|U|))$, system first undergoes from thermal Dirac semimetal CDW phase,...
