Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators
Advanced Materials, EarlyView.Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

Quantum Cosmology of Fab Four John Theory with Conformable Fractional Derivative
Universe, 2020 We study a quantization via fractional derivative of a nonminimal derivative coupling cosmological theory, namely, the Fab Four John theory. Its Hamiltonian version presents the issue of fractional powers in the momenta.

A general theory of the second quantization methods
, 1953 It is shown that the second quantization methods are a general mathematical technique applicable to formalisms involving linear equations of change, differential with respect to the time variable. The ordinary second quantization formalism for systems of

Advanced Materials, EarlyView.We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Exponentially more precise quantum simulation of fermions in second quantization
New Journal of Physics, 2016 We introduce novel algorithms for the quantum simulation of fermionic systems which are dramatically more efficient than those based on the Lie–Trotter–Suzuki decomposition.

BFV quantization and BRST symmetries of the gauge invariant fourth-order Pais-Uhlenbeck oscillator
Nuclear Physics B, 2022 We perform the BFV-BRST quantization of the fourth-order Pais-Uhlenbeck oscillator (PUO) for the first time. We show that although the PUO is not naturally constrained in the sense of Dirac-Bergmann, it is possible to profit from the introduction of ...

Stochastic integral representations of second quantization operators
, 2004 We give a necessary and sufficient condition for the second quantization operator Γ(h) of a bounded operator h on L2(R+), or for its differential second quantization operator λ(h), to have a representation as a quantum stochastic integral. This condition
