One the effect of the Vertical Axis Alignment on Cybersickness and Game Experience in Supine Posture

Ronan Boulic, Nana Tian, Louis Philippe Simoes Lopes

Cybersickness is still an inevitable adverse effect when using VR systems, resulting in different levels of discomfort, and potentially breaking the immersive experience. To date, few studies have focused on exploring VR experience in the supine posture. R ...

From NANOGrav to LIGO with metastable cosmic strings

Valerie Fiona Domcke

We interpret the recent NANOGrav results in terms of a stochastic gravitational wave background from metastable cosmic strings. The observed amplitude of a stochastic signal can be translated into a range for the cosmic string tension and the mass of magne ...

Localized Photon Lasing in a Polaritonic Lattice Landscape

Daniel Oberli, Marcia Portella Oberli, Fauzia Jabeen, Morteza Navadeh Toupchi

Periodic photonic structures have attracted much interest due to their versatility for controlling light propagation. The dispersion of photon modes in photonic lattices exhibits an energy band structure analo-gous to the electronic one in crystals. An imp ...

Amphiphilic gold nanoparticles perturb phase separation in multidomain lipid membranes

Francesco Stellacci, Ester Canepa, Giulia Rossi

Amphiphilic gold nanoparticles with diameters in the 2-4 nm range are promising as theranostic agents thanks to their spontaneous translocation through cell membranes. This study addresses the effects that these nanoparticles may have on a distinct feature ...

Aurora A depletion reveals centrosome-independent polarization mechanism in Caenorhabditis elegans

Pierre Gönczy, Coralie Busso, Christian Gentili, Kerstin Klinkert Fabbri, Lukas von Tobel, Marie Juliette Ségolène Pierron, Sarah Herrman

How living systems break symmetry in an organized manner is a fundamental question in biology. In wild-type Caenorhabditis elegans zygotes, symmetry breaking during anterior-posterior axis specification is guided by centrosomes, resulting in anterior-direc ...

The S-matrix bootstrap IV: multiple amplitudes

Jonathan Campbell Toledo

We explore the space of consistent three-particle couplings in Z(2)-symmetric two-dimensional QFTs using two first-principles approaches. Our first approach relies solely on unitarity, analyticity and crossing symmetry of the two-to-two scattering amplitud ...

Representations and descriptors unifying the study of molecular and bulk systems

Kevin Rossi

Establishing a unified framework for describing the structures of molecular and periodic systems is a long-standing challenge in physics, chemistry, and material science. With the rise of machine learning methods in these fields, there is a growing need fo ...

Quantum phase transitions beyond Landau-Ginzburg theory in one-dimensional space revisited

The phase diagram of the quantum spin-1/2 antiferromagnetic J(1)-J(2) XXZ chain was obtained by Haldane using bosonization techniques [Haldane, Phys. Rev. B 25, 4925 (1982); 26, 5257 (1982)]. It supports three distinct phases for 0

Dilaton-assisted generation of the Fermi scale from the Planck scale

Andrey Shkerin

In scale-invariant theories of gravity the Planck mass M-p, which appears due to spontaneous symmetry breaking, can be the only scale at the classical level. It was argued that the second scale can be generated by a quantum nonperturbative gravitational ef ...

Natural seesaw and leptogenesis from hybrid of high-scale type I and TeV-scale inverse

Majid Ekhterachian, Luca Vecchi

We develop an extension of the basic inverse seesaw model which addresses simultaneously two of its drawbacks, namely, the lack of explanation of the tiny Majorana mass term for the TeV-scale singlet fermions and the difficulty in achieving successful lept ...
