Shorter unentangled proofs for Ground State Connectivity
Libor Caha, Daniel Nagaj, Martin Schwarz
Can one considerably shorten a proof for a quantum problem by using a protocol with a constant number of unentangled provers? We consider a frustration-free variant of the QCMA-com…
Detection of a centrifugal magnetosphere in one of the most massive stars in the Oph star-forming cloud
S. Hubrig, M. Schöller, S. P. Järvinen +3
Recent XMM-Newton observations of the B2 type star rho Oph A indicated a periodicity of 1.205d, which was ascribed to rotational modulation. Since variability of X-ray emission in…
Molecule signatures in photoluminescence spectra of transition metal dichalcogenides
Maja Feierabend, Gunnar Berghaeuser, Malte Selig +4
Monolayer transition metal dichalcogenides (TMDs) show an optimal surface-to-volume ratio and are thus promising candidates for novel molecule sensor devices. It was recently predi…
An interacting adiabatic quantum motor
Anton Bruch, Silvia Viola Kusminskiy, Gil Refael +1
We present a field theoretic treatment of an adiabatic quantum motor. We explicitly discuss a motor termed Thouless motor which is based on a Thouless pump operating in reverse. Wh…
The European Quantum Technologies Roadmap
Antonio Acín, Immanuel Bloch, Harry Buhrman +15
Within the last two decades, Quantum Technologies (QT) have made tremendous progress, moving from Noble Prize award-winning experiments on quantum physics into a cross-disciplinary…
Counterion-release entropy governs the inhibition of serum proteins by polyelectrolyte drugs
Xiao Xu, Qidi Ran, Pradip Dey +4
Dendritic polyelectrolytes constitute high potential drugs and carrier systems for biomedical purposes, still their biomolecular interaction modes, in particular those determining…
Simulations of Coulomb systems confined by polarizable surfaces using periodic Green functions
Alexandre P. dos Santos, Matheus Girotto, Yan Levin
We present an efficient approach for simulating Coulomb systems confined by planar polarizable surfaces. The method is based on the solution of Poisson equation using periodic Gree…
Abelian Chern-Simons Theory for the Fractional Quantum Hall Effect in Graphene
Christian Fräßdorf
We develop a theory for the pseudorelativistic fractional quantum Hall effect in graphene, which is based on a multicomponent abelian Chern-Simons theory in the fermionic functiona…
Effects of two-loop contributions in the pseudofermion functional renormalization group method for quantum spin systems
Marlon Rueck, Johannes Reuther
We implement an extension of the pseudofermion functional renormalization group (PFFRG) method for quantum spin systems that takes into account two-loop diagrammatic contributions.…
The role of charge and proton transfer in fragmentation of hydrogen-bonded nanosystems: the breakup of ammonia clusters upon single photon multi-ionization
Bart Oostenrijk, Noelle Walsh, Joakim Laksman +4
The charge and proton dynamics in hydrogen-bonded networks are investigated using ammonia as a model system. The fragmentation dynamics of medium-sized clusters (1-2 nm) upon singl…
MSM/RD: Coupling Markov state models of molecular kinetics with reaction-diffusion simulations
Manuel Dibak, Mauricio J. del Razo, David De Sancho +2
Molecular dynamics (MD) simulations can model the interactions between macromolecules with high spatiotemporal resolution but at a high computational cost. By combining high-throug…
Evidence for a three-dimensional quantum spin liquid in PbCuTeO
S. Chillal, Y. Iqbal, H. O. Jeschke +9
The quantum spin liquid (QSL) is a highly entangled magnetic state characterized by the absence of static magnetism in its ground state. Instead, the spins fluctuate in a highly co…
Counting Periodic Trajectories of Finsler Billiards
Pavle V. M. Blagojević, Michael Harrison, Serge Tabachnikov +1
We provide lower bounds on the number of periodic Finsler billiard trajectories inside a quadratically convex smooth closed hypersurface in a -dimensional Finsler space with…
Combinatorics of Beacon-based Routing in Three Dimensions
Jonas Cleve, Wolfgang Mulzer
A beacon is a point-like object which can be enabled to exert a magnetic pull on other point-like objects in space. Those objects then move towards the beacon in a greedy fashion u…
Experimental Demonstration of Quantum Tunneling in IBM Quantum Computer
Narendra N. Hegade, Nachiket L. Kortikar, Bikramaditya Das +2
Quantum computers are the promising candidates for simulation of large quantum systems, which is a daunting task to perform in a classical computer. Here, we report the experimenta…
Chiral scatterers designed by Bayesian optimization
Philipp Gutsche, Philipp-Immanuel Schneider, Sven Burger +1
The helicity or chirality of scattered light is strongly linked to the dual symmetry of the scatterer. The latter depends on chiral materials or on scatterers which are not superim…
Data-driven Computation of Molecular Reaction Coordinates
Andreas Bittracher, Ralf Banisch, Christof Schütte
The identification of meaningful reaction coordinates plays a key role in the study of complex molecular systems whose essential dynamics is characterized by rare or slow transitio…
Determining the trisection genus of orientable and non-orientable PL 4-manifolds through triangulations
Jonathan Spreer, Stephan Tillmann
Gay and Kirby recently introduced the concept of a trisection for arbitrary smooth, oriented closed 4-manifolds, and with it a new topological invariant, called the trisection genu…
Bistability in Two Simple Symmetrically Coupled Oscillators with Symmetry-broken Amplitude- and Phase-Locking
André Röhm, Kathy Lüdge, Isabelle Schneider
In the model system of two instantaneously and symmetrically coupled identical Stuart-Landau oscillators we demonstrate that there exist stable solutions with symmetry-broken ampli…
Eigendecompositions of Transfer Operators in Reproducing Kernel Hilbert Spaces
Stefan Klus, Ingmar Schuster, Krikamol Muandet
Transfer operators such as the Perron--Frobenius or Koopman operator play an important role in the global analysis of complex dynamical systems. The eigenfunctions of these operato…
A search for the presence of magnetic fields in the two Supergiant Fast X-ray Transients IGR J08408-4503 and IGR J11215-5952
S. Hubrig, L. Sidoli, K. Postnov +4
A significant fraction of high-mass X-ray binaries are supergiant fast X-ray transients (SFXTs). The prime model for the physics governing their X-ray behaviour suggests that the w…
What it takes to shun equilibration
R. Gallego, H. Wilming, J. Eisert +1
Numerous works have shown that under mild assumptions unitary dynamics inevitably leads to equilibration of physical expectation values if many energy eigenstates contribute to the…
