Dirac equation in exotic spacetimes

2020-01-16T12:54:28+01:00Tags: , |

Authors: Faba Garcia, Javier; Sabin, Carlos Contribution: Article Journal: PHYSICAL REVIEW D Publication date: 2019/01/14 DOI: 10.1103/PhysRevD.99.025008 Abstract: We find solutions of the Dirac equation in curved spacetime. In particular, we consider 1 + 1 dimensional sections of several exotic metrics: the Alcubierre metric, which describes a scenario that allows faster-than-light velocity; the Godel metric, which [...]

Authors: Casanova, J.; Torrontegui, E.; Plenio, M. B.; Garcia-Ripoll, J. J.; Solano, E. Contribution: Article Journal: PHYSICAL REVIEW LETTERS Publication date: 2019/01/10 DOI: 10.1103/PhysRevLett.122.010407 Abstract: We develop energy efficient, continuous microwave schemes to couple electron and nuclear spins, using phase or amplitude modulation to bridge their frequency difference. These controls have promising applications in biological systems, [...]

Uncertainty relations for time-averaged weak values

Authors: Pollak, Eli; Miret-Artes, Salvador Contribution: Article Journal: PHYSICAL REVIEW A Publication date: 2019/01/08 DOI: 10.1103/PhysRevA.99.012108 Abstract: Time averaging of weak values using the quantum transition path time probability distribution enables us to establish a general uncertainty relation for the weak values of two not necessarily Hermitian operators. This new relation is a weak value analog [...]

Quantum dissipation of planar harmonic systems: Maxwell-Chern-Simons theory

2020-01-16T12:54:29+01:00Tags: , |

Authors: Valido, Antonio A. Contribution: Article Journal: PHYSICAL REVIEW D Publication date: 2019/01/03 DOI: 10.1103/PhysRevD.99.016003 Abstract: Conventional Brownian motion in harmonic systems has provided a deep understanding of a great diversity of dissipative phenomena. We address a rather fundamental microscopic description for the (linear) dissipative dynamics of two-dimensional harmonic oscillators that contains the conventional Brownian motion [...]

Ultrastrongly dissipative quantum Rabi model

Authors: Zueco, David; Garcia-Ripoll, Juanjo Contribution: Article Journal: PHYSICAL REVIEW A Publication date: 2019/01/03 DOI: 10.1103/PhysRevA.99.013807 Abstract: We discuss both the spectrum and the dynamics of cavity QED in the presence of dissipation beyond the standard perturbative treatment of losses. Using the dynamical polaron ansatz and matrix-product state simulations, we discuss the case where both light-matter [...]

Biosensors and chemical biology in the understanding and treatment of neurodegenerative diseases

2019-09-12T17:09:50+02:00

Valle Palomo (CIB, CSIC) Date & location: Thu 24 Jan 2019 12:00:00 GMT+0200 (CEST), Conference Room, Serrano 121 (CFMAC) Neurodegenerative diseases are complex pathologies with unknown etiology that lead to neural death. Their unknown etiology and complex molecular mechanisms has prevented the finding of effective therapies in the clinic. Biosensors allow for a detailed study of biological processes. [...]
