recommendations! Published in 2019 at "Journal of High Energy Physics"

DOI: 10.1007/jhep02(2019)015

Abstract: A bstractWe present a comprehensive study of the three-active plus N sterile neutrino model as a framework for constraining leptonic unitarity violation induced at energy scales much lower than the electroweak scale. We formulate a… read more here.

DOI: 10.1007/s10455-017-9571-3

Abstract: In this paper we study the dynamical zeta functions of Ruelle and Selberg associated with the geodesic flow of a compact hyperbolic odd-dimensional manifold. These are functions of a complex variable s in some right… read more here.

DOI: 10.1038/s41534-025-01145-3

Abstract: This paper presents a novel approach for implementing non-unitary basis transformations on quantum computational platforms, extending beyond conventional unitary methods. By integrating Singular Value Decomposition (SVD), the method achieves operational depth O(n) with about n… read more here.

DOI: 10.1080/10420150.2023.2186871

Abstract: A qubit lattice algorithm (QLA), which consists of a set of interleaved unitary collision-streaming operators, is developed for electromagnetic wave propagation in tensor dielectric media. External potential operators are required to handle gradients in the… read more here.

DOI: 10.1088/1367-2630/ade46f

Abstract: We elucidate the requirements for quantum operations that achieve environment-assisted invariance (envariance), a symmetry of entanglement. While envariance has traditionally been studied within the framework of local unitary operations, we extend the analysis to consider… read more here.

DOI: 10.1103/lwrz-jxrr

Abstract: We investigate the interplay between unitary and non-unitary driven many-body dynamics in (1+1)-dimensional quantum critical systems described by conformal field theory (CFT). By formulating a coherent state approach, we demonstrate that the growth of entanglement… read more here.

DOI: 10.1103/physrevb.104.214307

Abstract: We explore the multifractality of the steady state wave function in non-unitary random quantum dynamics in one dimension. We focus on two classes of random systems: the hybrid Clifford circuit model and the non-unitary free… read more here.

recommendations! Published in 2022 at "PLoS ONE"

DOI: 10.1371/journal.pone.0268838

Abstract: Research has usually considered cyberbullying as a unitary phenomenon. Thus, it has been neglected to explore whether the specific online aggressive behaviours relate differentially to demographic features of the perpetrators of online aggressive actions, their… read more here.
