Null energy constraints on two-dimensional RG flows
We study applications of spectral positivity and the averaged null energy condition (ANEC) to renormalization group (RG) flows in two-dimensional quantum field theory. We find a succinct new proof of the Zamolodchikov c-theorem, and derive further independ ...
New York2024A proof of the instability of AdS for the Einstein-massless Vlasov system
In recent years, the conjecture on the instability of Anti-de Sitter spacetime, put forward by Dafermos-Holzegel (Dynamic instability of solitons in 4 + 1 dimesnional gravity with negative cosmological constant, 2006. https://www.dpmms.cam.ac.uk/similar to ...
SPRINGER HEIDELBERG2022Coupling metric-affine gravity to a Higgs-like scalar field
General relativity (GR) exists in different formulations. They are equivalent in pure gravity but generically lead to distinct predictions once matter is included. After a brief overview of various versions of GR, we focus on metric-affine gravity, which a ...
AMER PHYSICAL SOC2022Comment on “Straight lightning as a signature of macroscopic dark matter”
In the discussed paper [N. Starkman, H. Winch, J. S. Sidhu, and G. Starkman, Straight lightning as a signature of macroscopic dark matter, Phys. Rev. D 103, 063024 (2021)], the authors have made several assumptions and statements concerning the initiation ...
2022Hole-induced anomaly in the thermodynamic behavior of a one-dimensional Bose gas
We reveal an intriguing anomaly in the temperature dependence of the specific heat of a one-dimensional Bose gas. The observed peak holds for arbitrary interaction and remembers a superfluid-to-normal phase transition in higher dimensions, but phase transi ...
SCIPOST FOUNDATION2022Modeling, estimation, and control in large-scale urban road networks with remaining travel distance dynamics
Nikolaos Geroliminis, Dimitrios Tsitsokas, Anastasios Kouvelas, Isik Ilber Sirmatel
City-scale control of urban road traffic poses a challenging problem. Dynamical models based on the macroscopic fundamental diagram (MFD) enable development of model predictive perimeter control methods for large-scale urban networks, representing an advan ...
2021Einstein-Cartan Portal to Dark Matter
Andrey Shkerin, Inar Timiryasov, Sebastian Zell
It is well known since the works of Utiyama and Kibble that the gravitational force can be obtained by gauging the Poincare group, which puts gravity on the same footing as the standard model fields. The resulting theory-Einstein-Cartan gravity-inevitably ...
AMER PHYSICAL SOC2021Observation of a singular Weyl point surrounded by charged nodal walls in PtGa
Oleg Yazyev, Jan Hugo Dil, Quansheng Wu, Shengnan Zhang
Constrained by the Nielsen-Ninomiya no-go theorem, in all so-far experimentally determined Weyl semimetals (WSMs) the Weyl points (WPs) always appear in pairs in the momentum space with no exception. As a consequence, Fermi arcs occur on surfaces which con ...
NATURE RESEARCH2021Wearable and Continuous Prediction of Passage of Time Perception for Monitoring Mental Health
David Atienza Alonso, Lara Orlandic, Adriana Arza Valdes
A person’s passage of time perception (POTP) is strongly linked to their mental state and stress response, and can therefore provide an easily quantifiable means of continuous mental health monitoring. In this work, we develop a custom experiment and Machi ...
2021Bootstrapping superconformal field theories in four dimensions
The conformal bootstrap is a non-perturbative technique designed to study conformal field theories using only first principles, such as unitarity, crossing symmetry and the existence of an Operator Product Expansion. In this thesis we discuss an applicatio ...
