In superconductors with multiple pairing channels, collective excitations known as "clapping modes" can arise in channels whose angular momenta differ from that of the pair condensate. Crystal symmetries often impose selection rules which keep these modes optically dark. We show that if pairing occurs around a single Fermi surface, trigonal warping renders clapping modes visible in the...

There are more particles than antiparticles in our universe. A simple solution to this unexpected asymmetry, known as the baryon asymmetry of our universe (BAU), is leptogenesis, where a heavy right-handed neutrino (RHN) is introduced. Interestingly, the mass of the RHN coincides with the energy scales during inflation. In addition to this outstanding problem, dark matter continues to be...

We ask how quantum correlations can be distributed among many subsystems. To address this, we define entanglement sharing schemes (ESS) where certain pairs of subsystems allow entanglement to be recovered via local operations, while other pairs must not. ESS schemes come in two variants, one where the partner system with which entanglement should be prepared is known, and one where it is not....

Specifically, we calculate the intrinsic spin current in a nonmagnetic noncentrosymmetric crystal in the presence of electron-lattice spin-orbit coupling. We show that the standard definition of the spin current operator in terms of an effective band Hamiltonian cannot be justified using a microscopic theory....

Motivated by the need for a more comprehensive algebraic structure to calculate coincidence probabilities of a general decay scheme for gamma ray spectroscopy, we model the decay scheme, rather naturally, as a quiver through which we define a decay quiver. The path algebra of quivers is the underlying, more general, algebra for transition matrices that is typically used in modelling decay...

Monolayer transition metal dichalcogenides have emerged as key materials for investigating the interplay between spin and valley degrees of freedom. The strong spin-orbit interaction and the lack of inversion symmetry in these materials result in a spin-valley locking, in which carriers in the K and K’ valleys possess opposite spin polarization. This effect is particularly pronounced for holes...

Atom interferometers are a form of quantum sensor in which matter waves are used for high-precision inertial sensing, such as gravimetry and gradiometry. Optimizing these sensors involves a careful design of the interferometer geometry, as well as improving the detection scheme that monitors internal and center-of-mass states of an atomic cloud.

We demonstrate that chains of bilayer graphene quantum dots (BLGQDs) can realize topological quantum matter by effectively simulating spin-1 chains that host the Haldane phase. Using an atomistic tight-binding model combined with exact diagonalization, we show that two electrons per quantum dot form a robust spin-1 ground state across interaction regimes. For coupled quantum dots, the...

Entanglement generation by beam splitters lies at the heart of quantum optics. Yet, the conjecture that maximal entanglement is generated by beam splitters with equal probabilities of reflection and transmission has remained unproved for two decades. I will show how we proved this conjecture by studying photon loss and found corollaries throughout quantum optics.

The nature of dark matter, and the origin of the matter-antimatter imbalance of the universe, are intriguing open questions in high-energy physics and cosmology. The breakdown of time-reversal symmetry (T) at ultra-high energy scales is believed to underlie one or both of these puzzles. However, these energy scales lie far above the reach of particle colliders. Fortunately, we can probe the...

The null results in direct detection motivate the exploration of a broader mass range for thermal relic dark matter (DM) candidates. An intuitive new place to extend these models is to consider masses in the MeV to GeV range. One way to do this and avoid bounds from the Cosmic Microwave Background is to introduce a dark sector consisting of a dark mediator and stable DM candidate.

Supernova (SN) localization from water-Cherenkov neutrino detectors is critical for capturing early optical observations of the next galactic SN, as neutrinos are the earliest observables arriving well before shock breakout. SN neutrino bursts detected by Super-Kamiokande (SK) produce thousands of PMT time-charge (TQ) signals which contain directional information. Our current direction...

Neuromorphic systems are circuit interconnects designed to emulate the neural processing of a biological brain. Artificial synapses can be reproduced by controlling emergent complex phenomena observed in a distinctive class of self-assembly (network) materials exhibiting memristive behaviour in their contact points. Such memristive interfaces work as smart resistive switches whose resistance...

We investigate how environmental noise and atomic state purity jointly shape entanglement dynamics in a two-atom cavity QED system described by the single-mode Tavis–Cummings model. The atoms are initially prepared either in maximally entangled Bell states or in mixed Werner states, while the cavity field is modeled by generalized single-mode squeezed coherent thermal states, allowing thermal...

The resonant state expansion (RSE), a rigorous perturbation theory recently developed in electrodynamics, is here applied to non-relativistic wave equation in one dimension. The resonant state (RSs) of a symmetric double quantum well structure superimposed by a combination of delta functions was first calculated. These RSs are then taken as an unperturbed basis for the RSE. The resonant state...

Radon and its decay products constitute significant sources of background in rare-event experiments, including dark matter and neutrino searches, due to their unavoidable origin from naturally occurring uranium. Both 222Rn and its long-lived progeny, 210Pb, can diffuse from detector material surfaces, resulting in persistent background contributions in low-background experiments. To study this...

The Global Argon Dark Matter Collaboration (GADMC) is designing a direct detection dark matter experiment using liquid argon, named ARGO. ARGO will utilize 400 tonnes of underground argon, with a fiducial volume of 300 tonnes. The activity of long-lived beta-emitter $^{39}$Ar will be reduced by at least a factor of 1000 in underground argon compared to atmospheric argon. This reduction...

Traditionally, phase transitions are considered in equilibrium. However, over the past decade there has been considerable interest in non-equilibrium or dynamical phase transitions (DPTs) where time plays the role of the control parameter and the transition happens at a critical time. DPTs have been primarily studied in the context of quantum many-body systems, including in experiments on cold...

The non-equilibrium dynamics of closed non-disordered quantum systems can be significantly affected by the presence of constraints. While equilibration generally takes place in these systems, it is often severely slowed down by a separation of timescales leading to pronounced metastability. Considering the triangular lattice quantum dimer model, we report on the existence of several relaxing...
