Critical Energies and Wigner Functions of the Stationary States of the Bose Einstein Condensates in a Double‐Well Trap

open access: yesAdvanced Quantum Technologies, EarlyView.
The critical parameters and energies, at which the wave function of the Bose Einstein Condensate in a double well trap exhibit the symmetry breaking, are estimated. The phase space representation of the states is obtained trough the Wigner function and the trends of the negativities are analyzed.

Boson features in STM spectra of cuprate superconductors: Weak-coupling phenomenology

open access: yes, 2014
We derive the shape of the high-energy features due to a weakly coupled boson in cuprate superconductors, as seen experimentally in Bi_2 Sr_2 Ca_1 Cu_2 O_8+x (BSCCO) by Lee et al. [Nature (London) 442, 546 (2006)].

Multi‐Photon Fock State Generation via Selective Single Photon Subtraction in a Cascaded Waveguide QED System

open access: yesAdvanced Quantum Technologies, EarlyView.
This work proposes a photon subtraction scheme, termed ′photon culling′, that enables the selective extraction of a single photon based on its arrival time relative to other photons. This scheme enables the generation of multi‐photon Fock states with high fidelity and modal purity, demonstrating significant potential for quantum metrology applications ...

Electroweak and QCD corrections to Higgs production via vector-boson fusion at the LHC

open access: yes, 2007
The radiative corrections of the strong and electroweak interactions are calculated at next-to-leading order for Higgs-boson production in the weak-boson-fusion channel at hadron colliders. Specifically, the calculation includes all weak-boson fusion and

Measurement of the associated production of a Higgs boson decaying into b-quarks with a vector boson at high transverse momentum in pp collisions at s=13 TeV with the ATLAS detector

open access: yesPhysics Letters B, 2021
The associated production of a Higgs boson with a W or Z boson decaying into leptons and where the Higgs boson decays to a bb¯ pair is measured in the high vector-boson transverse momentum regime, above 250 GeV, with the ATLAS detector. The analysed data,

An Introduction to Bosonization [PDF]

open access: yes, 2006
This is an expanded version of a lecture given at the {\it Workshop on Theoretical Methods for Strongly Correlated Fermions}, held at the {\it Centre de Recherches Math matiques}, in Montr al, from May 26 to May 30, 1999. After general comments on the relevance of field theory to condensed matter systems, the continuum description of interacting ...

Search for heavy resonances in final states with four leptons and missing transverse momentum or jets in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search for a new heavy boson produced via gluon-fusion in the four-lepton channel with missing transverse momentum or jets is performed. The search uses proton-proton collision data equivalent to an integrated luminosity of 139 fb −1 at a centre-of ...

Boson Dominance in nuclei [PDF]

open access: yes, 2004
We present a new method of bosonization of fermion systems applicable when the partition function is dominated by composite bosons. Restricting the partition function to such states we get an euclidean bosonic action from which we derive the Hamiltonian.

What physicalism could be

open access: yesAnalytic Philosophy, EarlyView.
Abstract The physicalist credo is that the world is physical. But some phenomena, such as minds, morals, and mathematics, appear to be nonphysical. While an uncompromising physicalism would reject these, a conciliatory physicalism need not if it can account for them in terms of an underlying physical basis.
