Simulating quantum circuits with tree tensor networks using density-matrix renormalization group algorithm Open
Quantum computing offers the potential for computational abilities that can go beyond classical machines. However, they are still limited by several challenges such as noise, decoherence, and gate errors. As a result, efficient classical s…

<i>Ab initio</i> approach to many-body quantum spin dynamics Open
A fundamental longstanding problem in studying spin models is the efficient and accurate numerical simulation of the long-time behavior of larger systems. The exponential growth of the Hilbert space and the entanglement accumulation at lon…

We report an improved measurement of the valence u and d quark distributions from the forward-backward asymmetry in the Drell-Yan process using 8.6 fb−1 of data collected with the D0 detector in pp¯ collisions at s=1.96. This analysis pro…

Combination of D0 measurements of the top quark mass Open
We present a combination of measurements of the top quark mass by the D0 experiment in the lepton+jets and dilepton channels. We use all the data collected in Run I (1992–1996) at √s=1.8 TeV and Run II (2001–2011) at √s = 1.96 TeV of the T…

Measurement of the top quark mass using the matrix element technique in dilepton final states Open
We present a measurement of the top quark mass in p (p) over bar collisions at a center-of-mass energy of 1.96 TeV at the Fermilab Tevatron collider. The data were collected by the D0 experiment corresponding to an integrated luminosity of…

Precise measurement of the top quark mass in dilepton decays using optimized neutrino weighting Open
We measure the top quark mass in dilepton final states of t (t) over bar events in p (p) over bar collisions at root s = 1.96 TeV, using data corresponding to an integrated luminosity of 9.7 fb(-1) at the Fermilab Tevatron Collider. The an…

Simultaneous measurement of forward-backward asymmetry and top polarization in dilepton final states fromproduction at the Tevatron Open
We present a simultaneous measurement of the forward-backward asymmetry and the top-quark polarization in tt¯ production in dilepton final states using 9.7 fb−1 of proton-antiproton collisions at s√=1.96 TeV with the D0 detector. To recons…
