The pion quasiparticle in the low-temperature phase of QCD
Bastian B. Brandt, Anthony Francis, Harvey B. Meyer +2
We extend our previous studies [PhysRevD.90.054509, PhysRevD.92.094510] of the pion quasiparticle in the low-temperature phase of two-flavor QCD with support from chiral effective…
Nucleon-to-Delta transition form factors in chiral effective field theory using the complex-mass scheme
M. Hilt, T. Bauer, S. Scherer +1
We calculate the form factors of the electromagnetic nucleon-to--resonance transition to third chiral order in manifestly Lorentz-invariant chiral effective field theory. For th…
Quantum Nondemolition Gate Operations and Measurements in Real Time on Fluctuating Signals
Yu Shiozawa, Jun-ichi Yoshikawa, Shota Yokoyama +10
We demonstrate an optical quantum nondemolition (QND) interaction gate with a bandwidth of about 100 MHz. Employing this gate, we are able to perform QND measurements in real time…
Band structure of CuMnAs probed by optical and photoemission spectroscopy
M. Veis, J. Minar, G. Steciuk +19
Tetragonal phase of CuMnAs progressively appears as one of the key materials for antiferromagnetic spintronics due to efficient current-induced spin-orbit torques whose existence c…
Positivity bound on the imaginary part of the right-chiral tensor coupling in polarized top quark decay
S. Groote, J. G. Körner
We derive a positivity bound on the right-chiral tensor coupling Im in polarized top quark decay by analyzing the angular decay distribution of the three-body polarized top q…
Cristal and Azurite: new tools for integration-by-parts reductions
Alessandro Georgoudis, Kasper J. Larsen, Yang Zhang
Scattering amplitudes computed at a fixed loop order, along with any other object computed in perturbative quantum field theory, can be expressed as a linear combination of a finit…
