Heavy fermions get nuclear boost on way to superconductivity
Heavy fermions nuclear boost superconductivity
2016/2/22
In a surprising find, physicists from the United States, Germany and China have discovered that nuclear effects help bring about superconductivity in ytterbium dirhodium disilicide (YRS), one of the m...
Universal contact of strongly interacting fermions at finite temperatures
Universal contact strongly interacting fermions finite temperatures
2010/11/23
The recently discovered universal thermodynamic behaviour of dilute, strongly interacting Fermi
gases also implies a universal structure in the many-body pair-correlation function at short distances,...
We use two fundamental theoretical frameworks to study the finite-size (shell) properties of the unitary gas in a periodic box: 1) an ab initio QuantumMonte Carlo (qmc) calculation for boxes containin...

Tunneling conductance in strained graphene-based superconductor: Effect of asymmetric Weyl-Dirac fermions
tunneling conductance strained graphene Specular Andreev reflection
2010/11/18
Based on the BTK theory, we investigate the tunneling conductance in a uniaxially strained graphene-based normal metal (NG)/ barrier (I)/superconductor(SG) junctions. In the present model, we assume t...
Nucleon to Delta transition form factors with $N_F=2+1$ domain wall fermions
Analysis of the $N_f=2+1$ lattice QCD results lowest-lying baryon masses covariant ChPT
2011/1/7
We calculate the electromagnetic, axial and pseudo-scalar form factors of the Nucleon to
(1232) transition using two dynamical light degenerate quarks and a dynamical strange
quark simulated with t...
We present a lattice study of up to N = 20 unitary fermions confined to a harmonic trap. Our
preliminary results show better than 1% agreement with high precision solutions to the many-body Schroding...
Exploration of the phase structure of $SU(N_c)$ lattice gauge theory with many Wilson fermions at strong coupling

2011/1/13
We explore aspects of the phase structure of SU(2) and SU(3) lattice gauge theories at strong
coupling with many flavours Nf of Wilson fermions in the fundamental representation, including
the relev...
Finite temperature QCD at fixed Q with overlap fermions
Finite temperature QCD fixed Q overlap fermions
2011/1/13
We present some preliminary results of the project on finite temperature QCD with overlap fermions at KEK.We performed a series of simulations to assess the effects of fixing the topological sector at...
Lattice calculation for unitary fermions in a finite box
Lattice calculation unitary fermions finite box
2011/1/14
A fundamental constant in systems of unitary fermions is the so-called Bertsch parameter, the
ratio of the ground state energy for spin paired unitary fermions to that for free fermions at the same d...
We present a lattice study of up to N = 20 unitary fermions confined to a harmonic trap. Our
preliminary results show better than 1% agreement with high precision solutions to the many-body Schroding...
Exotic magnetic orders for high spin ultracold fermions
Exotic magnetic orders high spin ultracold fermions
2010/10/27
We study Hubbard models for ultracold bosonic or fermionic atoms loaded into an optical lattice. The atoms carry a high-spin F > 1=2, and interact on site via strong repulsive Van
der Waals forces.
