Prospects for Bc+ and B+ → τ+ντ at FCC-ee

The prospects are presented for precise measurements of the branching ratios of the purely leptonic Bc+ → τ+ντ and B+ → τ+ντ decays at the Future Circular Collider (FCC). This work is focused on the hadronic τ(+) → π(+)π(+)π(-) nu(tau) decay in both Bc+ → ...

Emergence of Classical Magnetic Order from Anderson Towers: Quantum Darwinism in Action

Frédéric Mila

Environment is assumed to play a negative role in quantum mechanics, destroying the coherence in a quantum system and, thus, randomly changing its state. However, for a quantum system that is initially in a degenerate ground state, the situation could be d ...

Towards a Continuous Variable Quantum Compiler

Zoë Holmes

We present initial work towards an experimental implementation of a nonuniversal continuous variable quantum compiler capable of learning a linear phase operation with increased precision when quantum resources are used. ...

Momentum-resolved spin-conserving two-triplon bound state and continuum in a cuprate ladder

Henrik Moodysson Rønnow, Thorsten Schmitt, Yi Tseng

Studying multi-particle elementary excitations has provided unique access to understand collective many-body phenomena in correlated electronic materials, paving the way towards constructing microscopic models. In this work, we perform O K-edge resonant in ...

The Forward Physics Facility at the High-Luminosity LHC

Yiming Li, Yi Zhang, Lesya Shchutska, Raffaele Tito D'Agnolo, Enrico Bertuzzo, Alexey Boyarsky, Wei Liu, Francesco Cerutti

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located s ...

Vlasov description of the beam response to noise in the presence of wakefields in high-energy synchrotrons: beam transfer function, diffusion, and loss of Landau damping

Xavier Buffat, Sondre Vik Furuseth

Noise can have severe impacts on particle beams in high-energy synchrotrons. In particular, it has recently been discovered that noise combined with wakefields can cause a diffusion that leads to a loss of Landau damping after a latency. Such instabilities ...

Comparison of JET-C DD neutron rates independently predicted by the ASCOT and TRANSP Monte Carlo heating codes

Henri Weisen

Simulations of the DD neutron rates predicted by the ASCOT and TRANSP Monte Carlo heating codes for a diverse set of JET-C (JET with carbon plasma facing components) plasmas are compared. A previous study (Weisen et al 2017 Nucl. Fusion 57 076029) of this ...

A data-science approach to predict the heat capacity of nanoporous materials

Berend Smit, Mehrdad Asgari, Seyedmohamad Moosavi, Daniele Ongari, Andres Adolfo Ortega Guerrero, Elias Moubarak, Balázs Álmos Novotny, Özge Kadioglu

The heat capacity of a material is a fundamental property of great practical importance. For example, in a carbon capture process, the heat required to regenerate a solid sorbent is directly related to the heat capacity of the material. However, for most m ...

Measurement of the W gamma Production Cross Section in Proton-Proton Collisions at root s=13 TeV and Constraints on Effective Field Theory Coefficients

Jian Wang, Matthias Finger, Qian Wang, Chao Wang, Yiming Li, João Miguel das Neves Duarte, Matthias Wolf, Varun Sharma, Yi Zhang, Tian Cheng, Yixing Chen, Alexis Kalogeropoulos, Ioannis Papadopoulos, Yi Wang, Ekaterina Kuznetsova, Hua Zhang, Siyuan Wang, Jessica Prisciandaro, Peter Hansen, Xin Chen, Michele Bianco, Sebastiana Gianì, Davide Di Croce, Arvind Shah, Wei Sun, Jian Zhao, Rakesh Chawla, Jan Steggemann, Konstantin Androsov, Federica Legger, Doohyun Kim, Bertrand François, Bandeep Singh

A fiducial cross section for W gamma production in proton-proton collisions is measured at a center-of-mass energy of 13 TeV in 137 fb(-1) of data collected using the CMS detector at the LHC. The W -> e nu and mu nu decay modes are used in a maximum-likeli ...

Ultrafast photoelectron spectroscopy of photoexcited aqueous ferrioxalate

Majed Chergui, Frank van Mourik, Michele Puppin, Christopher Alexander Arrell, José Javier Pancracio Ojeda Andara, Luca Longetti, Thomas Roland Barillot

The photochemistry of metal-organic compounds in solution is determined by both intra- and inter-molecular relaxation processes after photoexcitation. Understanding its prime mechanisms is crucial to optimise the reactive paths and control their outcome. H ...

Integrated Magnetic-free Nitride Optical Isolator

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Jijun He, Anat Siddharth, Terence Albert Emile Blésin

We demonstrated an integrated magnetic-free optical isolator for Si3N4 photonics using AlN piezoelectric actuators via spatio-temporal modulation. By entering into the strong mode coupling regime, maximum of 9dB isolation and
