A Low Temperature Expansion for Matrix Quantum Mechanics
"... We analyze solutions to looptruncated SchwingerDyson equations in massless N = 2 and N = 4 WessZumino matrix quantum mechanics at finite temperature, where conventional perturbation theory breaks down due to IR divergences. We find a rather intricate low temperature expansion that involves fracti ..."

Systematic low temperature expansion in Ginzburg Landau model.
, 1999
"... Consistent perturbation theory for thermodynamical quantities in strongly type II superconductors in magnetic field at low temperatures is developed. It is complementary to the existing expansion valid at high temperatures. Magnetization and specific heat are calculated to two loop order and compare ..."

LowTemperature Expansion of the Free Energy in ASOS Model
, 1994
"... We calculate the lowtemperature series of the free energy in absolutevalue solidonsolid (ASOS) model to order u 23 using finitelattice method. The property of the obtained series and the behavior of their Padé approximants confirms us that the roughening transition in ASOS model is of Kosterlitz ..."

LOW–TEMPERATURE EXPANSION FOR A FIRST ORDER SURFACE TRANSITION
, 1993
"... The question concerning the possibility of a first order surface transition in a semi–infinite Blume–Capel model is addressed by means of low temperature expansions. It is found that such a transition can exist, according to mean field and cluster variation approximations, and contrarily to renormal ..."

Low temperature expansion of the gonihedric Ising model” heplat/9712002. 5
, 1996
"... We investigate a model of closed (d − 1)dimensional softselfavoiding random surfaces on a ddimensional cubic lattice. The energy of a surface configuration is given by E = J(n2 + 4k n4), where n2 is the number of edges, where two plaquettes meet at a right angle and n4 is the number of edges, wh ..."

there is no term proportional to the surface area, the bare surface tension of the model vanishes, in contrast to the ordinary Ising model. By a suitable adaption of Peierls argument, we prove the existence of infinitely many ordered low temperature phases for the case k = 0. A low temperature expansion
Effective Analysis of the O(N)Antiferromagnet: Low Temperature Expansion of the Order Parameter
, 1997
"... We investigate the low energy properties of Lorentzinvariant theories with a spontaneously broken rotation symmetry O(N) → O(N–1). The leading coefficients of the low temperature expansion for the partition function are calculated up to and including three loops. Emphasis is put into the special c ..."
