Quantum Electrodynamics in 2+1 Dimensions With Quenched Disorder: Quantum Critical States With Interactions and Disorder
(American Physical Society (APS), 20170626)Quantum electrodynamics in 2+1 dimensions (QED3) is a strongly coupled conformal field theory (CFT) of a U(1) gauge field coupled to 2N twocomponent massless fermions. The N=2 CFT has been proposed as a ground state of ... 
Quantum electrodynamics of accelerated atoms in free space and in cavities
(American Physical Society, 2006)We consider a gedanken experiment with a beam of atoms in their ground state that are accelerated through a singlemode cavity. We show that taking into account of the "counterrotating" terms in the interaction Hamiltonian ... 
Quantum Electronic Transport in Mesoscopic Graphene Devices
(20160514)Graphene provides a rich platform for the study of interactioninduced broken symmetry states due to the presence of spin and sublattice symmetries that can be controllably broken with external electric and magnetic fields. ... 
Quantum Engineering with Mechanical Strain
(20210712)Qubits (quantum bits) have many different physical realizations, each with their own strengths and weaknesses. Futuristic quantum networks will require carefully designed interactions between different types of qubits, ... 
Quantum enhanced metrology in the optical lattice clock
(20230314)Highbandwidth, highstability clocks offer unique chances to study fundamental physics beyond simple metrology. Today, the most stable clocks are optical lattice clocks and they can reach a fractional stability of 3.1 × ... 
Quantum entanglement and dynamics of lowdimensional quantum manybody systems
(20230512)Entanglement as a fundamental aspect of quantum mechanics plays a crucial role in manybody systems. Quantum dynamics, due to the intricate interplay between the locality of the interaction and the nonlocal nature of ... 
Quantum entanglement between an optical photon and a solidstate spin qubit
(Nature Publishing Group, 2010)Quantum entanglement is among the most fascinating aspects of quantum theory1. Entangled optical photons are now widely used for fundamental tests of quantum mechanics2 and applications such as quantum cryptography1. Several ... 
Quantum Error Correction for Metrology
(American Physical Society (APS), 2014)We propose and analyze a new approach based on quantum error correction (QEC) to improve quantum metrology in the presence of noise. We identify the conditions under which QEC allows one to improve the signaltonoise ratio ... 
Quantum fluctuations in the presence of thin metallic films and anisotropic materials
(IOP Publishing, 2006) 
Quantum Fluids of SelfAssembled Chains of Polar Molecules
(American Physical Society (APS), 2006)We study polar molecules in a stack of strongly confined pancake traps. When dipole moments point perpendicular to the planes of the traps and are sufficiently strong, the system is stable against collapse but attractive ... 
Quantum Flutter: Signatures and Robustness
(American Physical Society (APS), 2014)We investigate the motion of an impurity particle injected with finite velocity into an interacting onedimensional quantum gas. Using largescale numerical simulations based on matrix product states, we observe and ...

A Quantum Gas Microscope for Detecting Single Atoms in a HubbardRegime Optical Lattice
(Nature Publishing Group, 2009)Recent years have seen tremendous progress in creating complex atomic manybody quantum systems. One approach is to use macroscopic, effectively thermodynamic ensembles of ultracold atoms to create quantum gases and strongly ... 
Quantum Gas Microscopy of Strongly Correlated Bosons
(20230509)A system of ultracold atoms in an optical lattice provides a powerful platform for quantum simulation. In our laboratory, we use a quantum gas microscope to tune lattice parameters not only in a global scale but also at ... 
Quantum geometry of refined topological strings
(Springer Verlag, 2012)We consider branes in refined topological strings. We argue that their wavefunctions satisfy a Schrodinger equation depending on multiple times and prow this in the case where the topological string has a dual matrix model ... 
Quantum Hall Conductance of TwoTerminal Graphene Devices
(American Physical Society, 2009)Measurement and theory of the twoterminal conductance of monolayer and bilayer graphene in the quantum Hall regime are compared. We examine features of conductance as a function of gate voltage that allow monolayer, ... 
Quantum Hall drag of exciton condensate in graphene
(Springer Nature, 2017)Exciton condensate is a BoseEinstein condensate (BEC) of electron and hole pairs bound by the Coulomb interaction1,2. In an electronic double layer (EDL) under strong magnetic fields, filled Landau states in one layer ... 
Quantum Hall Effect, Screening, and LayerPolarized Insulating States in Twisted Bilayer Graphene
(American Physical Society (APS), 2012)We investigate electronic transport in dualgated twistedbilayer graphene. Despite the subnanometer proximity between the layers, we identify independent contributions to the magnetoresistance from the graphene Landau ... 
Quantum Hall to Insulator Transition in the Bilayer Quantum Hall Ferromagnet
(American Physical Society, 2008)We describe a phase transition of the bilayer quantum Hall ferromagnet at \(\nu=1\). In the presence of static disorder (modeled by a periodic potential), bosonic \(S=\frac{1}{2}\) spinons undergo a superfluidinsulator ... 
Quantum heat waves in a onedimensional condensate
(American Physical Society, 2017)We study the dynamics of phase relaxation between a pair of onedimensional condensates created by a bidirectional, supersonic 'unzipping' of a finite single condensate. We find that the system fractures into different ...
