Advanced Science, EarlyView.High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Advanced Science, EarlyView.Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

Advanced Science, EarlyView.First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

Proceedings of the twenty-fifth annual ACM symposium on Theory of computing - STOC '93, 1993
In this paper we study quantum computation from a complexity theoretic viewpoint. Our first result is the existence of an efficient universal quantum Turing machine in Deutsch's model of a quantum Turing machine (QTM) [Proc. Roy. Soc. London Ser. A, 400 (1985), pp. 97--117].

Summary: We survey the field of quantum information theory. In particular, we discuss the fundamentals of the field, source coding, quantum error-correcting codes, capacities of quantum channels, measures of entanglement, and quantum cryptography.

Physical Review B, 1992
We present an exact solution of a one-dimensional (1D) model: a particle of incident energy E colliding with a target which is a 1D harmonic «solid slab» with N atoms in its ground state; the Hilbert space of the target is restricted to the (N+1) states with zero or one phonon present. For the case of a short-range interaction V(z) between the particle

The author defines a formal language AQT (axiomatic quantum theory) whose terms are built from three kinds of variables (scalars, vectors, operators), and among others Dirac's ``kets'' and ``bras''. The axioms are chosen such that elementary properties of operator variables for instance can be derived.

On the Completeness of Quantum Theory
Synthese, 1974This is an essay on the interpretation of quantum theory. I take the central interpretive problem to be the problem of completeness. Partial assignments of values to the quantities are forced out by the 0 and 1 probabilities of the theory. Can we complete the assignments so as to assign values in superposed states? What is at stake is the very capacity

IT is well known that the transformation theory of quantum mechanics corresponds to the property of the classical equations of motion of being invariant with respect to contact transformations. These are simultaneous transformations of co-ordinates xk (including time) and momenta pk (including energy), such that the difference of pkdxk in the old and ...
