Quark matter inside neutron stars

Abstract: I will describe recent advances in the theoretical description of the cold and dense deconfined matter possibly found inside the cores of neutron stars. Novel attempts to understand the bulk thermodynamic behavior of this exotic matter using on one hand perturbative QCD and on the other hand the gauge/gravity duality are introduced, and the implications of the new results on the observable properties of neutron stars are discussed.

Precise perturbative flavor symmetry breaking in D decays

Abstract: Flavor SU(3) has been known to describe adequately hadronic charmed meson decay amplitudes with SU(3) breaking corrections of 20-30%. I will describe a new approach treating perturbatively high order SU(3) breaking. I will focus on predicted amplitude relations affected by tiny fourth order SU(3) breaking terms varying between 10^{-3} and 10^{-4}. SU(3) relations failing at such high precision could provide evidence for new physics in the flavor sector.

The proton charge radius puzzle

Abstract: There is a proton charge radius puzzle because the proton charge radius appears different when measured with electrons than when measured with muons. Explanations broadly fit into two categories. “Ordinary” explanations include problems with the extrapolations or theoretical corrections involved in the measurements, and “exotic” explanations include such beyond the standard model ideas as a breakdown of electron-muon universality. We will discuss something of how the measurements are done, and discuss possible explanations in both the “ordinary” and “exotic” categories.

Decoherence in Inflation

Abstract: During inflation, cosmological scalar perturbations can be described by the Sasaki-Mukhanov variable. Quantizing this variable, we get a highly quantum mechanical, `squeezed’ vacuum state. However, it is common in cosmology to use classical perturbation theory to describe the perturbations after their birth. In this talk I will discuss some properties of the squeezed vacuum state, and show how decoherence can be used to understand the transition from the quantum mechanical initial conditions to the classical treatment. In decoherence, the system gets entangled with its environment, so that its reduced density matrix becomes an ensemble of classically observable states.

Spread of entanglement in holographic theories

Abstract: In this talk I will present recent results of the propagation of entanglement entropy after a global quench in the context of AdS/CFT. I will start by reviewing the heuristic picture for entanglement propagation dubbed as ‘entanglement tsunami’, and explain why this interpretation fails for general theories and entangling regions. In the second part of the talk I will present an analytic perturbative calculation for small subregions and show that in this regime the spread of entanglement exhibit some distinct features: i) the instantaneous rate of growth is not constrained by causality, but rather its time average, and ii) the saturation is always continuous, regardless the shape of the entangling region. I will also comment on the generalization of these results for non-relativistic scale invariant theories in some generic examples (1602.05934).

Cholesterol, tiny but tough! How membranes sense changes in cholesterol structure.

Abstract: Cholesterol is one of the vital components in regulating the physical properties of animal cell membranes. Further, there are membrane proteins whose function is dependent on cholesterol, however the mechanisms and physical principles used by cholesterol to modulate protein function remain unknown. What makes cholesterol exceptionally intriguing is the fact that other sterols are not able to replace cholesterol, thus its structure is unique in a manner that is not yet understood. In this talk, we discuss how cell membranes sense cholesterol and changes in its structure. We consider synthetic sterols non-existent in nature to elucidate the roles of cholesterol’s individual structural elements. This brings out the critical components in cholesterol structure that are critical to its function. To clarify how reactive oxygen species affect cholesterol and its role in cell function, we also discuss how oxysterols based on oxidation of cholesterol affect membrane properties that turn out to be distinct from those induced by cholesterol. We further discuss how cholesterol is able to govern cellular signaling by modulating the structure and dynamics of membrane receptors that manage the signaling between the outside and the inside of cells. The data emerged from molecular simulations as well as experiments provide a basis to better understand why cholesterol is indeed unique in modulating membrane properties and membrane protein function, and the insight found by simulations can possibly be used to predict new synthetic sterols with applications in biotechnology.

The case for dark matter self interactions – evidence in Abell 3827?

Abstract: I will review motivations for the existence of self interacting dark matter and discuss possible astrophysical observables. Self-interactions of dark matter particles can potentially lead to an observable separation between the dark matter halo and the stars of a galaxy moving through a region of large dark matter density. Such a separation has recently been observed in a galaxy falling into the core of the galaxy cluster Abell 3827. I discuss the DM self-interaction cross section needed to reproduce the observed effects.

Revisiting compressed SUSY at LHC

Abstract: Recently a compressed mass spectrum has been thought as an explanation for the elusiveness of low-energy supersymmetry (SUSY). Some characteristic signals at the Large Hadron Collider, such as mono-jet + missing transverse energy (MET), had been propounded as its trademark signals. However, later investigations suggested that lower limits on the supersym- metric particle masses would be quite stringent in spite of compression. Also, most compressed SUSY scenarios studied so far are only partially compressed. By keeping the level of compression in the entire spectrum as high as possible we study a broad class of benchmark spectra, ensuring consistency with the observed Higgs mass as well as the dark matter constraints. We show that of both the multi-jet +MET and mono-jet + MET final states, the former is still more efficient to reveal a compressed SUSY spectrum first, while the latter can serve as a useful confirmatory channel.

Relativistic effects on LSS spectrum and bispectrum

Abstract: I will discuss the Large Scale Structure spectrum and bispectrum in a relativistic framework. To first order, a relativistic description includes terms beyond the Kaiser approximation (doppler effects and galaxy evolution), gravitational potentials and integrated terms (cosmic magnification, integrated Sachs-Wolfe and Shapiro time-delay). These terms are currently neglected, but they might play a role in future surveys which probe larger scales. I will show how they can be isolated by correlating different probes, or by using the so-called multi-tracer technique. Moreover, some relativistic effects could give a non-negligible contribution to the LSS observables, hence, by neglecting them, the analysis may lead to biased cosmological parameters.
