Casimir Stabilization of Fluctuating Electronic Nematic Order
Vacuum cavity control of quantum materials is the engineering of quantum materials systems through electromagnetic zero-point fluctuations. In this work we articulate a generic mechanism for vacuum optical control of correlated electronic order: Casimir control, where the zero-point energy of the electromagnetic continuum, the Casimir energy, depends on the properties of the material system. To assess the experimental viability of this mechanism we focus on the Casimir stabilization of fluctuat…

Casimir-Lifshitz theory for cavity-modification of ground-state energy
A theory for ground-state modifications of matter embedded in a Fabry-Perot cavity and whose excitations are described as harmonic oscillators is presented. Based on Lifshitz's theory for vacuum energy and employing a Lorentz model for the material permittivity, a non-perturbative macroscopic QED model was built that accounts for the infinite number of cavity modes with a continuum of their wavevectors. Differences from the commonly used single-mode Hopfield Hamiltonian are revealed. The non-re…

Casimir Interaction between Polydisperse Colloids Trapped at a Fluid Interface
We investigate the effect of polydispersity on fluctuation-induced interactions between Janus colloidal particles trapped at a fluid interface. Using the scattering-matrix formalism, we calculate the thermal Casimir energy in both two- and three-body systems, considering three distinct fluctuation scenarios for the colloids: (a) fixed, (b) bobbing, and (c) bobbing and tilting. Our results reveal a pronounced sensitivity to polydispersity that strongly depends on the fluctuating boundary conditi…

New Junction Condition and Casimir effect for Network CFT
Recently, BCFT and ICFT have been generalized to the CFT on networks (NCFT). A key aspect of NCFT is how we connect the CFTs in different edges at the nodes of the network. For a free scalar field, one naturally requires that the scalar fields are continuous at the nodes. In this paper, we introduce a new junction condition that instead requires the normal derivative of the scalar field to be continuous at the node. We demonstrate that this new junction condition is consistent with the variatio…

Yukawa-Casimir wormholes within Einstein-Cartan gravity framework
The Einstein-Cartan (EC) theory of gravity provides a natural extension of general relativity by incorporating spacetime torsion to account for the intrinsic spin of matter. In this work, we investigate Yukawa-Casimir traversable wormholes supported by three distinct Yukawa-Casimir energy density profiles within the framework of EC gravity. The resulting shape functions are shown to satisfy all the fundamental requirements for traversable wormhole geometries. Our analysis reveals that the prese…

Combining the second data release of the European Pulsar Timing Array with low-frequency pulsar data
Low-frequency radio data improve the sensitivity of pulsar timing arrays (PTAs) to propagation effects such as dispersion measure (DM) variations, enabling better noise characterization essential for detecting the stochastic gravitational wave background (GWB). We combined LOFAR (100-200 MHz) and NenuFAR (30-90 MHz) observations with the recent European and Indian PTA release (DR2new+) into a new dataset, DR2low, spanning ~11 years for 12 pulsars. DR2low allows updated noise models, increasing …

The influence of the Casimir effect on the binding potential for 3D wetting
We provide comprehensive details of how a previously overlooked entropic, or low temperature Casimir contribution, $W_C$, to the total binding potential for 3D short-ranged wetting may be determined from a microscopic Landau-Ginzburg-Wilson Hamiltonian. The entropic contribution comes from the many microscopic configurations corresponding to a given interfacial one, which arise from bulk-like fluctuations about the mean-field (MF) constrained profile, and adds to the usual MF contribution $W_{M…
