Understanding the L-shell ionization mechanism through osmium atoms bombarded by 4-6 MeV/u fluorine ions

Soumya Chatterjee, Sunil Kumar, Sarvesh Kumar +9

The L-subshell ionization mechanism is studied in an ultra-thin osmium target bombarded by 4-6 MeV/u fluorine ions. Multiple ionization effects in the collisions are considered thr…

Supersymmetric lattice fermions on the triangular lattice: superfrustration and criticality

L. Huijse, D. Mehta, N. Moran +2

We study a model for itinerant, strongly interacting fermions where a judicious tuning of the interactions leads to a supersymmetric Hamiltonian. On the triangular lattice this mod…

Small Quadrupole Deformation for the Dipole Bands in 112In

T. Trivedi, R. Palit, J. Sethi +24

High spin states in In were investigated using Mo(O, p3n) reaction at 80 MeV. The excited level have been observed up to 5.6 MeV excitation energy and spin $…

't Hooft-Polyakov monopoles in lattice SU(N)+adjoint Higgs theory

S. Edwards, D. Mehta, A. Rajantie +1

We investigate twisted C-periodic boundary conditions in SU(N) gauge field theory with an adjoint Higgs field. We show that with a suitable twist for even N one can impose a non-ze…

First results of evaporation residue cross-section measurements of S+Pb system

R. Sariyal, I. Mazumdar, D. Mehta +9

The dynamics of heavy ion-induced reactions play a critical role in forming super heavy elements (SHE), and one clear signature of the SHE formation is the evaporation residue (ER)…

Fast Ion Surface Energy Loss and Straggling in the Surface Wake Fields

T. Nandi, K. Haris, Hala +10

We have measured the stopping powers and straggling of fast, highly ionized atoms passing through thin bilayer targets made up of metals and insulators. We were surprised to find t…

Exact results for the star lattice chiral spin liquid

G. Kells, D. Mehta, J. K. Slingerland +1

We examine the star lattice Kitaev model whose ground state is a a chiral spin liquid. We fermionize the model such that the fermionic vacua are toric code states on an effective K…

Stability and symmetry breaking in a three Higgs-boson doublet model with lepton family symmetry O(2)xZ2

M. Maniatis, D. Mehta, Carlos M. Reyes

Motivated by the neutrino data, an extension of the Standard Model with three Higgs-boson doublets has been proposed. Imposing an O(2) x Z2 family symmetry, a neutrino mixing matri…

Measurements of evaporation residue cross-sections and evaporation residue-gated -ray fold distributions for S+Sm system

R. Sariyal, I. Mazumdar, D. Mehta +11

Evaporation Residue (ER) cross-sections and ER-gated -ray fold distributions are measured for the S + Sm nuclear reaction above the Coulomb barrier at six differ…

L shell x-ray production in high-Z elements using 4-6 MeV/u fluorine ions

Sunil Kumar, Udai Singh, M. Oswal +5

L shell line and total x-ray production cross sections in 78Pt, 79Au, 82Pb, 83Bi, 90Th, and 92U targets ionized by 4-6 MeV/u fluorine ions were measured. These cross sections are c…
