Phase-Space Contractions of Carrollian Black-Hole Thermodynamics

Yingnan Xu, Shuangshuang Chu · 2026

We study Carrollian limits of Schwarzschild-AdS black-hole thermodynamics using covariant phase space. Allowing the cosmological constant to vary, we derive the extended Iyer-Wald identity and identif…

Absence of Quasi-Majorana False Positives in Full-Shell Hybrid Nanowires

Carlos Paya, Cesar Robles, Pablo San-Jose, Elsa Prada · 2026

Tunneling spectroscopy cannot be used as an unambiguous detection tool for Majorana zero modes (MZMs) in conventional partial-shell nanowires. The presence of smooth confinement at the end of the hybr…

Stationary solutions in the small-$c$ expansion of GR

Enes Bal, Ertugrul Ekiz, Emre Onur Kahya, Utku Zorba · 2026

We study the small-$c$ expansion of general relativity in ADM variables up to next-to-next-to-leading order (NNLO). We show that, in the stationary sector, this formulation renders the field equations…

Carrollian quantum states and flat space holography

Stefan Fredenhagen, Stefan Prohazka, Robert Tiefenbacher · 2026

We study free Carrollian quantum field theories from an algebraic perspective and explore their implications for flat space holography. As explicit examples, we construct the electric and magnetic Car…

Coulomb Potential in Podolsky-Carroll-Field-Jackiw Electrodynamics

D. S. Cabral, L. A. S. Evangelista, A. F. Santos · 2026

Podolsky electrodynamics, a higher-derivative extension of Maxwell's theory characterized by the Podolsky parameter $\lambda=1/m$, which modifies the photon dispersion relation and regularizes short-d…

Carroll fermions, expansions and the lightcone

Arjun Bagchi, Saikat Mondal · 2026

We investigate fermions on Carrollian manifolds. We complement previous intrinsic analysis by deriving Carrollian fermion actions from a relativistic Dirac theory via a systematic expansion in the spe…

Statistical Signatures of Majorana Zero Modes in Disordered Topological Superconductor Antidot Vortices

Zhibo Ren, Jukka I. Vayrynen · 2026

An antidot-pinned vortex in a three-dimensional topological insulator-superconductor platform hosts a Majorana zero mode (MZM). However, numerous Caroli-de Gennes-Matricon (CdGM) states coexist with i…

On Carrollian Loop Amplitudes for Gauge Theory and Gravity

Vijay Nenmeli, Bin Zhu · 2026

Carrollian amplitudes are scattering amplitudes of massless particles written in position space at null infinity. We study various aspects of Carrollian amplitudes for gauge theory and gravity at loop…

A Twisted Origin for Magnetic Carroll Supersymmetry

Ilayda Bulunur, Osman Ergec, Oguzhan Kasikci, Mehmet Ozkan, Mustafa Salih Zog · 2026

Magnetic Carrollian theories provide a natural setting for field theories with nontrivial spatial structure in the Carroll limit and are therefore natural candidates for flat-space holographic duals. …

High energy scattering and null strings

Arjun Bagchi, Sachin Grover, Sharang Rajesh Iyer, Amartya Saha · 2026

We propose an instrinsic worldsheet description of the ultra-high energy regime of string scattering based on worldsheet symmetries. At very high energies, the fundamental string becomes tensionless a…

The Carrollian Superplane and Supersymmetry

Andrew James Bruce · 2026

This note provides an intrinsic construction of the Carrollian superplane $\Pi \mathbb{S}\simeq \mathbb{R}^{2|4}$ as a supermanifold generalisation of the Carrollian plane. Moving away from the $c\rig…

How did the Urban Network Flow Adapt to the Collapse of the Carola Bridge?

Jyotirmaya Ijaradar, Ning Xie, Lei Wei, Sebastian Pape, Matthias Korner, Meng Wang · 2026

The unexpected collapse of the Carola Bridge in Dresden, Germany, provides a rare opportunity to characterise how urban network traffic adapts to an unexpected infrastructure disruption. This study de…

Two-time physics, Carroll symmetry and Jordan algebras

Alexander Kamenshchik, Alessio Marrani, Federica Muscolino · 2026

We describe Carroll particles with nonzero energy (i.e., particles that remain at rest) within the framework of two-time (2T) physics developed by Bars and collaborators. In a spacetime with one addit…

Approximate Models for Gravitational Memory

Q-L Zhao, P.-M. Zhang, M. Elbistan, P. A. Horvathy · 2026

The large-distance development of a sandwich gravitational wave, consistent with Carroll symmetry, provides us with a surprisingly good analytic approximation of the motion of particles in a wave with…

Two Times for Freudenthal

Alexander Kamenshchik, Alessio Marrani, Federica Muscolino · 2026

We investigate the algebraic structure of the two-time physics introduced some time ago by I. Bars and his co-authors, clarifying its relations with quadratic and cubic Jordan algebras, as well as wit…

Black hole Near Horizons through the Looking Glass

Arjun Bagchi, Arkachur Bhattacharya, Sharang Rajesh Iyer, K. Narayan · 2026

We show that the near horizon of a generic non-extremal black hole (BH) can be understood in terms of a Carrollian geometry with two null directions, also called a String-Carroll (SC) geometry. The ba…

Limits on the Carroll-Field-Jackiw electrodynamics from geomagnetic data

G. F. de Carvalho, M. Fillion, P. C. Malta, C. A. D. Zarro · 2026

Lorentz-symmetry violation may be described via the CPT-odd, dimension-3, Carroll-Field-Jackiw term, which couples the electromagnetic fields to a constant 4-vector $k_{\rm AF}$ selecting a preferred …
