2021/8/11
Researchers are proposing a new way to modulate both the absorptive and the refractive qualities of metamaterials in real time, and their findings open intriguing new opportunities to control, in time...
Asymptotic limits and the structure of the pion form factor
Dispersion technology solve meson chiral perturbation theory high energy low energy limit
font style='font-size:12px;'>
2014/12/22
We use dispersive techniques to address the behavior of the pion form factor as Q2 → ∞ and Q2 → 0. We perform the matching with the constraints of perturbative QCD and chiral perturbation theory in th...
Upper limits on the observational effects of nuclear pasta in neutron stars

2011/7/21
The effects of the existence of exotic nuclear shapes at the bottom of the neutron star inner crust - nuclear `pasta' - on observational phenomena are estimated by comparing the limiting cases that th...
Detection limits in plasmonic whispering gallery mode biosensors
plasmonic whispering gallery mode biosensors
font style='font-size:12px;'>
2011/9/5
We analyze a whispering gallery mode biosensor with a metallic nanorod bound to its surface. It is found that a localized surface plasmon resonance in the nanorod can reduce the optical mode volume of...
Large-N limits of 2d CFTs, Quivers and AdS_3 duals
Large-N limits 2d CFTs
font style='font-size:12px;'>
2010/12/24
We explore the large-N limits of 2d CFTs, focusing mostly on the WZW model and cosets. The $SU(N)_k$ theory is parametrized in this limit by a 't Hooft-like coupling. We show a duality between strong ...
Near Horizon Limits of Massless BTZ and Their CFT Duals
Near Horizon Limits Massless BTZ Their CFT Duals
font style='font-size:12px;'>
2010/12/23
We consider the massless BTZ black hole and show that it is possible to take its "near horizon" limit in two distinct ways. The first one leads to a null self-dual orbifold of AdS3 and the second to a...

2010/12/24
We revisit the study of the maximally singular point in the Coulomb branch of 4d N=2 SU(N) gauge theory with N_f=2n flavors for N_f<2N. When n >= 2, we find that the low-energy physics is described b...
Quantum singular operator limits of thin Dirichlet tubes via $\Gamma$-convergence
Quantum singular operator limits thin Dirichlet tubes $\Gamma$-convergence
font style='font-size:12px;'>
2010/11/11
The $\Gamma$-convergence of lower bounded quadratic forms is used to study the singular operator limit of thin tubes (i.e., the vanishing of the cross section diameter) of the Laplace operator with Di...
Limits on Preserving Quantum Coherence using Multi-Pulse Control

font style='font-size:12px;'>
2010/10/19
We explore the physical limits of pulsed dynamical decoupling methods for decoherence control
as determined by finite timing resources. By focusing on a decohering qubit controlled by arbitrary seque...

2010/10/19
Secure two-party cryptography is possible if the adversary’s quantum storage device suffers imperfections.For example, security can be achieved if the adversary can store strictly less then half of th...
Atomic Fock states by gradual trap reduction: from sudden to adiabatic limits
Atomic Fock states gradual trap reduction: sudden adiabatic limits

2010/10/18
We investigate the possibility to form high delity atomic Fock states by gradual reduction of
a quasi one dimensional trap containing spin polarized fermions or strongly interacting bosons in the To...
Classical limits of boost-rotation symmetric spacetimes
boost-rotation symmetry C-metric Newtonian limit
font style='font-size:12px;'>
2010/3/18
Boost-rotation symmetric spacetimes are exceptional as they are the only exact asymptotically flat solutions to the Einstein equations describing spatially bounded sources ("point-like" particles, bla...
Universal quantum limits on single channel information, entropy and heat flow

2010/10/13
We show that the recently discovered universal upper bound on the thermal conductance of a single channel comprising particles obeying arbitrary fractional statistics is in fact a consequence of a mor...
