FPO - Jingyu Luo - Search for long-lived particles decaying into displaced jets with the CMS detector at the Large Hadron Collider

Mon, Jul 22, 2019, 10:00 am

The existence of long-lived particles is very generic in many beyond standard model scenarios. A search for long-lived particles decaying into jets is presented in this dissertation. Data were collected with the CMS detector at the LHC from proton-proton collisions at a center-of-mass energy of 13 TeV in 2016, corresponding to an integrated...

FPO - Ksenia Bulycheva - SYK Model and its Generalizations

Fri, Jul 19, 2019, 11:00 am

We briefly review the Sachdev–Ye–Kitaev (SYK) model and study several generalizations of it. First, we consider an SYK model with global U(1) charge and find its four-point function in Euclidean and real time.

Biophysics Seminar Series: Jaume Casademunt, University of Barcelona: Hydrodynamics of epithelia: waves, wetting, and fingering| PCTS Seminar room, Jadwin 407

Fri, Jun 14, 2019, 12:30 am

Collective migration of cohesive groups of cells is a hallmark of the tissue remodeling events that underlie embryonic morphogenesis, wound repair and cancer invasion. In this collective migration, supra-cellular properties such as collective polarization or force generation emerge and eventually control large- scale...

HEP Seminar - Dr.Catalina Oana Curceanu-The Frascati National Laboratory of the INFN- "The Schroedinger Cat Meets the Neutron Stars: From Exotic Atoms Studies to Impossible Atoms Hunting"

Thu, Jun 13, 2019, 2:00 pm

I shall present a series of frontier experiments searching for X rays coming from exotic atoms produced at the DAFNE collider of LNF-INFN (Italy) and from processes violating Quantum Mechanics’ predictions at the Italian Gran Sasso underground laboratory.

Physics Group Meeting at IAS | Ahmed Almheiri, School of Natural Sciences, IAS | “The Entanglement Wedge of an Evaporating Black Hole”

Wed, Jun 12, 2019, 1:45 pm

I will discuss recent work that studies the evolution of the von Neumann entropy of a holographic boundary system dual to an evaporating black hole in AdS.


FPO - Alex Song - “Large-scale volumetric in-vivo two photon calcium imaging”

Tue, Jun 11, 2019, 4:00 pm

Neural activity is widely distributed and highly integrated, yet individual neurons are generally thought of as the computational unit of the brain. Decoding this activity and behavior is thought to require simultaneous recording from large populations of neurons at fast timescales.

Gordon & Betty Moore Foundation Seminar at IAS | Catalina Oana Curceanu, Frascati National Laboratory of the INFN | “Testing Collapse Models Underground by Searching the Spontaneous Radiation (How to go from “to be AND not to be” to “to be OR not to be”)”

Fri, Jun 7, 2019, 1:45 pm

We are experimentally investigating possible violations of standard quantum mechanics predictions in the Gran Sasso underground laboratory in Italy. In particular, we are testing the collapse models, proposed as a solution of the measurement problem (Schroedinger cat paradox), by chasing the spontaneous radiation predicted by these models in...


FPO - Zhenbin Yang - “Gravitational Dynamics of Near Extremal Black Holes”

Fri, Jun 7, 2019, 10:00 am

This thesis is devoted to trying to understand the quantum mechanics of gravity. We consider the low energy dynamics of near extremal black holes. We find that the gravitational dynamics of near extremal black holes are controlled by a one dimensional effective action and the quantum mechanics of the effective action is solvable...

Physics Group Meeting at IAS | Jerome Gauntlett, Imperial College London | "Geometric Extremization for Supersymmetric $AdS_3$ and $AdS_2$ Solutions"

Wed, Jun 5, 2019, 1:45 pm

We consider supersymmetric $AdS_3\times Y_7$ solutions of type IIB supergravity dual to N=(0,2) SCFTs in


Gordon & Betty Moore Foundation Seminar at IAS | Catalina Oana Curceanu, Frascati National Laboratory of the INFN | “Challenging the Pauli Exclusion Principle by Hunting “Impossible” Atoms in the Cosmic Silence”

Tue, Jun 4, 2019, 2:00 pm

We are experimentally investigating possible violations of the Pauli Exclusion Principle in the cosmic silence of the Gran Sasso underground laboratory in Italy, by hunting "impossible" atomic transitions.

HET Seminar | Natalia Pinzani-Fokeeva, KU Leuven | "Holographic Schwinger-Keldysh effective field theories"

Tue, May 28, 2019, 2:00 pm

Hydrodynamics has been recently reformulated as an effective field theory based on an underlying Schwinger-Keldysh partition function.


FPO - Mallika Randeria - Imaging Quantum Hall Wavefunctions With A Scanning Tunneling Microscope: From Spontaneous Symmetry Breaking To Interacting Domain Boundary Modes

Mon, May 20, 2019, 10:30 am

Quantum materials provide a rich platform for realizing emergent phenomena, where interactions between electrons lead to properties that are strikingly different from those of individual electrons.

FPO - Jie Wang - "Berry Phase in Composite Fermi Liquids"

Fri, May 17, 2019, 10:00 am

Two-dimensional electron gas in high magnetic field exhibits a wide variety of interesting physical properties. Perhaps most notable of these is the quantum Hall effect, which is a classic example of a topological phase. Another interesting phase occurs at even denominator filling fraction is the so-called ``composite Fermi liquid''.

Physics Group Meeting at IAS | Rashid Sunyaev | “Two Important Milestones in the History of the Universe: The Last Scattering Surface, the Black Body Photosphere of the Universe and Distortions of the CMB Spectrum”

Wed, May 15, 2019, 1:45 pm

: Our Universe is filled with Cosmic Microwave Background (CMB) radiation having an almost perfect black body spectrum with a temperature of To=2.7K.


Pheno & Vino Seminar | Laura Chang, Princeton University | "A search for dark matter annihilation in the Milky Way halo" | Jadwin 303

Tue, May 14, 2019, 4:00 pm

The Milky Way halo is the brightest source of dark matter (DM) annihilation on the sky. Indeed, the strength of the Galactic dark matter signal can be greater than that expected from dwarf galaxies even in regions away from the Inner Galaxy.

FPO - Thomas Hazard - "Improving Quantum Hardware: Building New Superconducting Qubits and Couplers"

Fri, May 10, 2019, 10:00 am

Over the past 10 years, improvements to the fundamental components in supercon- ducting qubits and the realization of novel circuit topologies have increased the life- times of qubits and catapulted this architecture to become one of the leading hardware platforms for universal quantum computation.

FPO - Stephane Cooperstein - "Observation of Higgs boson decay to bottom quarks"

Thu, May 9, 2019, 3:00 pm

The observation of the Standard Model Higgs boson decay to a bottom quark-antiquark pair is presented. The primary contribution to this result is from processes in which the Higgs boson is produced in association with a W or Z boson.
